Traditionally, the Nezavisimost group of companies helped us to understand the potential malfunctions of the Evoque, and it is worth noting that some of the complaints were not confirmed in the official statistics. However, we still found a few "sores", and all of them - as a selection: in theory, any of them will make you think about whether it is worth messing with the "Ewok". is it so bad? Let's find out now!
Burning pistons on a 2.0 Si4 engine
Let's start right away with heavy artillery. Burning pistons sounds ominous, and this alone can scare many people away from buying a car. Unfortunately, this problem is all too familiar to some owners of two-liter Si4 Ewoks. In the Land Rover family of compact crossovers, this engine replaced the 3.2-liter six-cylinder unit that was installed on the Freelander model as the flagship. An economical, compact, powerful and high-torque motor that provides excellent dynamics - it would seem, what else is needed?
But reliability is also needed, and it was with this point that the Si4 motor did not immediately go smoothly. A burning Jackie Chan, erratic engine performance, and tailpipe smoke were classic potential engine companions, and any of these signs could mean either burnt pistons or broken partitions between the rings. This happened, as a rule, during dynamic driving, that is, the piston group simply could not withstand the increased loads.
In "Independence", however, they reassure: the problem is solved, but it consisted in incorrect software. Alla Martynova, technical director of the Jaguar Land Rover and Volvo business unit, said that the manufacturer solved the problem by replacing the engine control unit software as part of a service campaign, so at present such a malfunction should not occur with a gasoline Evoque.
intercooler pipe burst
"... 2 days ago we encountered such a problem as power limitation. This is when you drive, you drive, and the speed drops sharply to 40 km / h and no longer allows you to accelerate. And the most interesting thing is that it happened on two cars at once on the same day Before that, it simply didn’t let it accelerate, but on the second car the icon was on, and it let it go, and then it completely disappeared ... ", - says user Natalia on the www.range-rover-evoque.ru forum.
If owners of gasoline Evoques could be scared by burning pistons, then diesel Evoque TD4s have another horror story - a bursting intercooler pipe. He turned out to be too thermophilic, and in severe frosts he became tanned, cracked and lost tightness.
As the user VALIUM writes on the same range-rover-evoque.ru forum, this pipe "if it hasn't burst now, it will definitely burst", and advises replacing the original part with an analogue from ... KamAZ. It is made of silicone and is much less susceptible to temperatures and loads.
In Nezavisimost, however, they are much more optimistic: they can do without KamAZ trucks, since the problem has already been solved. "This complaint was encountered on diesel engines in a very narrow range of VIN numbers. The problem was in the quality of components - it was solved by the manufacturer as part of a service campaign. For gasoline engines - the problem is not relevant," says Alla Martynova.
Knocking when maneuvering at low speeds
"Bucket with English bolts!" - the owners sometimes grumble after meeting with the "speed bump" or during maneuvers in a bumpy parking lot. At times, the Evoque can "jump" off its dignified British gait and starts to noticeably squeak and rumble on bumps with all its suspension - both front and rear.
“When speed bumps are passing at a very low speed, a dull single knock appears (as if there is play in the movement of shock absorbers or levers), and, interestingly, both in the front and rear suspension. The sound is heard at the moment the wheel rolls onto the speed bump ... ", - says user Mikhail77777 on the range-rover-evoque.ru forum.
Official dealers were familiar with this problem: the noisy suspension turned out to be an unpleasant design feature, which the manufacturer has already got rid of.
"The problem was solved by the manufacturer by replacing the suspension mounting elements with improved ones. Within the framework of a service bulletin from the manufacturer," says Alla Martynova.
Gearbox not coming out
However, not all malfunctions, the mention of which can be found among the owners of the Evoque, have been confirmed by the officials. This happened, for example, with such a fashionable “trick” of Jaguar Land Rover as a gear selector washer. The selector gracefully hides in the same plane with the console, and when the engine starts, it smoothly moves back. Gears are switched by turning the puck. Very stylish and beautiful process! However, the problem is that sometimes this puck won't come out and the driver can't even move. Or - even more interesting - it crawls out, and then immediately coquettishly hides back, as if flirting.
Such electronics failures could be explained by low temperatures, however, judging by the reviews, the selector frills do not depend on the weather and season. Restart helped someone, but someone went straight to the dealer in every possible way.
According to representatives of "Independence", they have not met with such complaints. However, it is worth noting that a technical bulletin on this subject has been issued by the manufacturer - too many owners have complained that the switch does not rise or switch between modes. According to the bulletin, official dealers carried out diagnostics and reset errors in the "brains", and if this did not help, then everything ended with a warranty replacement of this very washer - the so-called TRS unit (transmission rotary switch).
Of course, the owners of classmates-competitors can gloat and be in full confidence that they definitely made the right choice and bought the most reliable and trouble-free car. But there are no perfect cars - and the fact that your favorite model has not yet appeared in this section means only one thing: we just haven't got to it yet.
First of all, I would like to note that below is an overview of the most common malfunctions. This in no way means that all this will certainly happen to your car. Also, over time, perhaps some sores will be added to the list.
The main malfunctions of the Range Rover Sport (2005-2013):
Engine 5.0L, petrol, supercharged:
Deterioration of the tensioner and damper of the timing chain. In the event of this malfunction, more recently there was a need to replace, including the timing chain. But in accordance with the recently released tech. bulletin, the need to replace the chain has disappeared.
Symptoms - extraneous noise from dv-la.
--- Faulty blower.
Symptoms - extraneous noise from the supercharger. The method of repair is the installation of a special repair kit (at first it was necessary to change the supercharger assembly, later the manufacturer released a repair kit).
--- Malfunction of the water pump.
Symptoms - extraneous noise, pump leak.
Engine 4.2L, petrol, supercharged (Supercharged):
Additional pump of the cooling system. As a result, an error is fixed by the control unit and forced power limitation.
--- Thermostat failure.
Symptoms - the engine does not warm up to operating temperature or cools down quickly.
--- Malfunction of the heater radiator in the cabin.
Engine 4.4L, gasoline:
Valve of the crankcase ventilation system. Symptoms - smoke from the muffler, high oil consumption in the engine.
--- Malfunction of lambda probes, a problem with the toxicity reduction system - only when using low-quality fuel.
Engine 3.6l, turbodiesel:
Crack in the pipe / pipes from the intercooler to the intake manifold.
Symptoms - loss of power.
--- Faulty EGR valves.
Symptoms - failures during acceleration, loss of power.
--- Malfunction of fuel injectors (nozzles) appears when using low-quality fuel. Cleaning / restoration of injectors is impossible, if they fail, only replacement with new ones.
--- During long-term parking, the turbine drive may become soured. Sometimes it is possible to restore their performance without replacing the turbine.
--- Fuel pump in the tank.
Engine 3.0 diesel:
EGR shut-off valve located between the first and second turbine.
Symptoms of its malfunction are loss of power, an error in boost pressure.
--- EGR cooler leak. The leak can be both outside (which is much more often) and inside the cooler, while there are no smudges, but the level of antifreeze drops. When leaking inside, antifreeze enters the turbocharger, which negatively affects its durability.
--- Wear of the blades of the second turbine. It appears extremely rarely. The reasons for the occurrence are still not clear, most likely a factory defect. Repair is not possible, only the replacement of the turbine.
--- Malfunction of fuel injectors (nozzles) appears when using low-quality fuel. Cleaning / restoration of injectors is impossible, if they fail, only replacement with new ones.
AKP malfunction. In 90% of cases, it is necessary to repair the automatic transmission itself and the torque converter. In 10% of cases, both automatic transmission and torque converter and valve body (valve block).
--- IMPORTANT! The need to change the oil is every 48,000 km (against 240,000 km as prescribed before).
Transfer case (RK):
Stretching the chain (mainly with very active driving).
--- Oil leakage from the sump and / or electrical connector of the automatic transmission.
Suspension and air suspension:
Suspension compressor
--- Body height sensors, sensor wiring.
--- Pneumatic bridging valves (front/rear).
Symptoms - the front or rear of the car drops.
--- Suspension shock absorbers (from 100,000 km). It makes sense to change the rack assembly with PN pillows, since the difference in price is not great.
--- Lower front suspension arms
--- Steering tips, rods
--- Rear suspension sliding joints
--- Rear axle toe rods
--- Rear silent blocks of the upper arms of the rear suspension.
Transmission, brakes:
Front wheel bearings (hub assembly).
Symptoms - hum when moving.

Symptoms - hum when moving.
--- Differential lock motor.
Symptoms - failure of several systems at once.
--- Handbrake unit. Regular maintenance of this unit is recommended - 1 time in 2 replacement of the rear brake pads.
--- The right bracket of the handbrake cable is frayed. In this case, the handbrake cable gets on the rim and can be frayed.
--- Breakage of the outboard bearing of the rear driveshaft (rarely).
Heater in salon:
Malfunction of the heater radiator (only relevant for 4.4l and 4.2l petrol engines).
Symptoms - warm air on the passenger side, cold air on the driver's side.
Additional heater (Webasto):
Software failure of the electronic control unit.
--- Burnout or cracked burner.
Symptoms - increased smoke during operation or inoperability of the heater.

Emergency indication in carsRange Rover
A car of such a class as the Range Rover has a reliable light indication, which is displayed on the scoreboard, which allows you to judge the malfunction of a particular node and take the necessary actions or make the right decision.
Possible malfunctions in the engine management system
The main indicator among the entire group of display elements is the Check-Engine - check the engine. This indicator lights up for a short time when the ignition is turned on, when all indicators are being tested. After which it should turn off. If it lights up while driving or works in a flickering mode, this means there is a malfunction in the engine. The panel may also display the inscription - "ENGINE MALFUNCTION" and this means that some kind of malfunction has occurred and it is necessary to contact a car service without delay.
The most likely causes of the "Check Engine" light on diesel engines
- In Range Rover diesel models, versions 3.0 TD, 3.6 TD, 4.4 TD, the ignition of this indicator may be caused by a malfunction of the exhaust gas recirculation valves - USR. The high pressure fuel pump (TNVD) or the booster pump, which is located in the fuel tank, may also be faulty. Maybe one of the fuel injectors is faulty.
- On the Range Rover 3.0 TD, the bypass flow system through the bypass valve often fails. This system includes vacuum lines, the valve itself and the control solenoid valve. During diagnostics, all lines, electrical wiring are checked, and only then should they be replaced bypass- valve.
- The weak point of all models, and especially the Range Rover 3.6 TD, are rubber air boost hoses. They are not very reliable and often break, so the sensors “see” an inappropriate amount of air in the line and the system switches the engine to a limited mode, while the display lights up - “Power Limit”. In order not to be in an unpleasant situation, it is necessary every 20-30 thousand km. mileage, replace these hoses.
Oil stains can be observed at the air hose connections, but this is not a problem, since the intake system sucks in excess oil that is burned in the combustion chamber, preventing it from being released into the atmosphere. Why is the destruction of the hoses. During the operation of diesel turbines of a Range Rover car, the hoses are constantly inflated, and when regassing, the hoses pulsate - they are either filled with air or compressed. From this, their tightness is broken, and they become covered with cracks and tear.
If the air hoses are leaking, oil droplets flying out of the air pipe fall onto the cooling system hoses, and since the antifreeze system hoses are not oil resistant, they swell under the action of oil and can jump off their seats.
In the practical operation of cars, this happens quite often, therefore, as soon as strong oil stains appear on the air hoses, the pipes must be changed immediately. The diesel engine of the Range Rover 3.0 TD car has a hose running from the intercooler (heat exchanger) to the throttle assembly. This hose often breaks, which leads to a limitation in the power of the diesel engine.
The most serious trouble that the "Check Engine" can indicate is a malfunction of any of the turbines. The Range Rover diesel turbines themselves are quite reliable, but they are equipped with an electronic-mechanical actuator that controls the flow of boost. The vacuum actuator is designed to protect the turbine from overloads at high speeds. Over time, the actuator rod may become jammed or the rod hole coked, after which the control electromagnetic mechanism is not able to move the rod and the control system puts the engine in a limited mode. The first thing to do is to try to design the actuator stem by hand. If this does not work out, then the turbine needs to be replaced, since the actuator and control solenoid valve are not sold separately, which excludes its replacement. Sometimes it can help to contact a service center, but they also will not give a 100% guarantee.
The most probable causes of the "Check engine» on gasoline engines
Range Rover vehicles are also equipped with gasoline engines.
These are the models:
- 4.2SC (Supercharger)
- 4.4NA (Atmospheric)
- 5.0 SC (Supercharger) since 2010
- 5.0 NA (Atmospheric) since 2010
The most common reason for the check engine light to come on is a cylinder misfire. This malfunction is eliminated by cleaning the injectors or replacing the spark plugs. The next, very common cause of a Range Rover gasoline engine malfunction is the supply of an over-enriched or over-lean mixture. This may be caused by the presence of leaks when air is sucked from the air line or a decrease in the performance of the fuel pump located directly in the fuel tank.
On engines 4.2 SC and 5.0 SC, according to the error code, when conducting diagnostics, it is possible to clearly fix precisely the decrease in the performance of the fuel supply pump. On the 4.4 NA engine, there is no pressure sensor, and it will not be possible to obtain data using the diagnostic system, but if the service department has adapters and pressure gauges, then this defect can be detected.
A fairly common cause of a malfunction in Range Rover gasoline engines is a failure of oxygen sensors in the catalytic exhaust gas aftertreatment system or a malfunction directly related to the catalysts. The cost of one branded catalyst is 90,000 rubles, and there are two of them on a Range Rover car, in addition, the cost of oxygen sensors must be taken into account.
The result is a rather impressive amount, so many car owners prefer to put the so-called "tricks" or even remove the catalysts. This leads to the fact that the operation of the entire logic of the gasoline engine management system is disrupted, since it is based on the readings of the oxygen sensors of the exhaust gas cleaning system. And when instead of regular catalysts "blendes" are put or catalysts are completely removed - this leads to inadequate operation of the control system. A reasonable way out of this situation is to contact such service departments that not only change the catalysts to cheaper ones, but can also reprogram the control system.
On the 4.2 SC (Superchardger) engine, such a malfunction as a failure of the additional electric pump of the supercharger system is quite common. As a result, the supercharger overheats excessively and the thermal sensors, through the control system, limit the engine power. Of course, before changing the electric pump, it is necessary to check its power supply system.
On Range Rover vehicles with 5.0 SC and 5.0 NA engines, a malfunction associated with the timing chains is very common. It all starts with the fact that with a run of 50,000 km or more, noises can be observed in the front of the engine, which increase with increasing mileage. This is caused by loosening of the timing chain tension. This causes the valve timing to be off, causing the engine malfunction indicator to come on.
Since 2010, all these engines began to install the VVT clutch (Variable Valve Timing System) on all camshafts, which complicated the chain circuit system. In addition, the not entirely successful design of the chain tensioners causes a weakening of the tightness and a beating of the chain with all the ensuing consequences. In this case, you have to change all chains, tensioners and all additional elements. In our services, the price of this service is within 110,000 rubles.
One of the standard malfunctions on Range Rover vehicles equipped with gasoline engines is a defect in the fuel vapor purification system in order to reduce their toxicity. To comply with environmental standards, fuel vapors are vented through an adsorbing filter and when the evacuation and cleaning system is faulty, an engine malfunction indicator is triggered. Although, as a rule, engine power is not reduced, fuel consumption is not increased either. If such a malfunction is determined by an error code during diagnostics, then the adsorption filter and the check valve on the fuel line must be replaced. Such a malfunction occurs on runs of 120,000 km or more.
Critical warning signal
The critical warning signal is indicated by a red light and, in fact, warns of a critical situation associated with any part of the car. Along with the critical warning indicator, another indicator lights up, which allows you to specify the malfunction or an information text appears that explains the cause of the critical warning. If the text is not visible, you need to scroll through all the messages by pressing the "OK" button, which is located on the steering wheel.
Oil pressure indicator
The oil pressure indicator in the system is one of the most important indicators on the dashboard of a Range Rover car. When the ignition is turned on, this indicator should light up and go out after 2-3 seconds. If you observe the “flickering” of this indicator, its glow for more than 3 seconds at start-up or its periodic ignition while driving, regardless of the type of engine, you must immediately stop driving and turn off the engine of your car.
The first step is to check the oil level in the engine of your Range Rover. Using a conventional probe, this can be done quickly and easily, but if you use an electronic probe, then you must wait 10-15 minutes after turning off the ignition. If the oil level has fallen below the minimum limit, it is necessary to look for the point of its leakage.
Practice shows that constantly adding oil to the engine, and only in the case of a small leak, you can reach the car service. Such experiments are generally very dangerous - you can completely destroy the engine. Years of practice have shown that the oil level indicator in any Range Rover engine does not light up even when the oil level is minimal, and the indication only works on low oil pressure in the engine oil system, and this is already too late. Therefore, as soon as the oil level indicator lights up or even blinks, you must immediately turn off the engine and call a technical assistance vehicle.
Brake indicator
This indicator should come on when the ignition is turned on and go out after a few seconds. If the engine of your Range Rover is running and this indicator is lit red, this means a defect in the brake system. This, first of all, can mean a decrease in the level of brake fluid or a “sticking” of the float, which is extremely rare. A low brake fluid level indicates a leak from the Range Rover system. The main reason is a broken or leaking brake hose. Quite often there are problems with the wiring of the ABS (anti-lock braking system) power line, but then, along with the brake system indicator, the ABS and DSC indicators light up. On earlier Range Rover models (2006-2009), this indicator glowed bright orange if the brake pad sensor was triggered, but the message “CHECK BRAKE PADS” was displayed on the panel. True, this was not on all trim levels, and which pads: front or rear, were also not indicated.
Parking brake indicator
This indicator lights up red when the parking brake is applied and goes out when the vehicle is released. If the indicator "blinks" - this means a malfunction. For all Range Rover models, the parking brake is controlled by an electromagnetic mechanism that tightens the cables, but the latest Range Rover models, starting in 2013, have an electromagnetic actuator system that is built into the calipers and clamps and unclenches the main rear wheel pads, acting as a parking brake.
You should be aware that on the latest Range Rover models, the parking brake turns on and off automatically. You turned off the engine and the car applied the parking brake, you started the engine and the brake disengaged. In addition, if some serious malfunction has occurred with the machine, the parking brake is also activated automatically. Even if the battery is completely discharged, the Range Rover is equipped with a dedicated backup battery for the parking brake.
For Russian conditions, this is not very convenient, since the car cannot even be towed anywhere, but the British have a different mentality: there is a tow truck and service road services to move a faulty car.
Parking brake problems on a Range Rover
There can be several reasons for parking brake malfunctions in Range Rover vehicles:
- The mechanics of the parking brake pads are not adjusted and when the electromagnetic actuator tightens the cables, this happens unevenly, which causes the malfunction indicator to work. In this case, it is enough to adjust the mechanics of the parking brake of the Range Rover car.
- The parking brake pads of the Range Rover were crumbling from wear and tear. In the process of wear, the pads become thinner, which disrupts the symmetrical movement of the cables and causes the fault indicator to go off.
- Malfunction of the parking brake cables themselves. Their outer coating is destroyed by friction, dirt gets inside, the movement of the cable becomes difficult and, as a result, the system is decalibrated and the electronic unit fails.
- Failure of the electronic control module
In the event of a malfunction of the parking brake of a Range Rover car, all work must be carried out in a certain sequence. First you need to carefully inspect the parking brake cable system. If the cables of the Range Rover car are in perfect order, it is necessary to remove the brake discs and adjust the parking brake pads. If the entire mechanical part is in perfect order, you can proceed to computer diagnostics of the electronic unit.
If an external examination of the unit did not give anything, it is necessary to reflash it and erase all fault codes from memory. If this does not help, then it remains only to replace the electronic unit with a serviceable one. If your Range Rover has a problem with the parking brake, you should always be prepared for a big expense, since everything is interconnected in this system. First it turns out that the cables are frayed, then after removing the discs it turns out that the brake pads are no good, therefore, you need to change the cable system and pads, and at the same time the discs.
In the end, it turns out that the electronic unit is also faulty, and it is located in a hard-to-reach place. Therefore, it probably makes sense to replace everything at once, since it is cheaper in bulk, and you can drive calmly. It is important to know that you cannot install a used electronic unit, since it is registered for a specific vin (Vehicle Identification Number) of the car and with computer diagnostics, all electronic devices of your Range Rover can be “infected” with an extraneous number and the car simply will not go.
There may also be such a defect that, along with the flashing parking brake indicator, the brake system malfunction indicator is lit, but the parking brake is working. This may be the case when a short circuit occurs between the individual conductors due to the drying of the wire insulation. To eliminate this defect, it is enough to find the place of the short circuit and insulate the wires with poor insulation. If it happens that on your Range Rover car, the parking brake is jammed, then it can be easily removed manually. To do this, you need to open the trunk, there, in a special pocket, there is a loop, by pulling which you can unclench the parking brake pads.
Battery charging indicator
This light comes on when you turn on the ignition on your vehicle and goes out after the engine has started. If the indicator does not go out or lights up while driving, this means that there is a malfunction in the battery charging system of your Range Rover. The most common malfunction, both on diesel and gasoline engines, is the failure of the generator, which will have to be replaced. You can send it in for repair and put it back in, but practice shows that repaired generators are very unreliable and in any case you will have to buy a new generator.
Glow plug indicator
This indicator is placed only on Range Rover vehicles equipped with diesel engines. When the ignition is turned on, it glows orange, indicating the operation of the candles. You need to wait for this indicator to turn off and only then start the engine. Since 2010, Range Rover cars have been equipped with automatic equipment, which, after pressing the "Start" button, will wait for the glow plugs to warm up and only then start the engine. The system tests the glow plugs that heat up the combustion chamber. True, this indicator does not signal poor performance of the spark plugs. Even resistance measurements will not show the real picture.
The best test is to remove the spark plugs and connect them to a voltage source. One candle heats up in 1 second, the second in 2 seconds, the third in an even longer period of time. They are all good, but if symptoms of a cold start appear, all candles should be replaced. It should also be taken into account that in the cold season, the candles continue to work at half power for approximately 30-40 seconds, providing stable ignition in all cylinders.
Dynamic Suspension Fault Indicator
This indicator can glow orange or red. An orange glow indicates a suspension failure, but the vehicle may be driven in the middle (normal) or low suspension position. The red color of the indicator indicates a serious malfunction of the suspension, and you should drive the car with the utmost care until qualified assistance is available.
If the indicator is lit orange, this indicates a malfunction of the suspension pneumatic system. This malfunction is considered the most common in Range Rover vehicles. This could be a compressor failure:
- Overheat
- Weak performance
- Short circuit of the motor winding
Also, in the air suspension, electromagnetic pneumatic valves or suspension height sensors, as well as all the electrical wiring of the elements of the air suspension system, can fail.
If the indicator is red, then this indicates that the Range Rover active stabilization system, which has been installed on these cars since 2013, is faulty. On the model from 2013, a system of hydraulic cylinders is mounted, which minimizes the roll of the car when making sharp turns. The most common hydraulic system failures are:
- Leakage of hydraulic fluid from the system
- Other elements of the active stabilization valve body, electromagnetic solenoids
- Accelerometer
Range Rover active stabilizers can leak and lose hydraulic fluid. If this is not noticed in time, the failure of the hydraulic pump itself is quite possible. The most common cause of electromagnetic solenoids failure is wiring failure, and the accelerometer may fail with frequent and fast driving on “humped” roads.
Malfunction in the ABS system
If the indicator does not go out after starting the engine, when all indicators are being tested, or lights up when the car is moving, this means a malfunction of the anti-lock system. On Range Rover vehicles, the ABS can be blocked due to various malfunctions. For example, a defective rear differential can cause the ABS module to disengage. Quite often, the wiring of the ABS sensors is broken, and the sensors themselves can fail due to a broken hub bearing.
Active safety system
If this sensor comes on while driving, the active safety system is malfunctioning and the airbags may not deploy as a result. There may be several reasons for this error:
- Malfunction of the belt tensioner, which is also the lock where the belt is fixed. Instantaneous tension of the belt, in the event of an accident, occurs due to the operation of the squib
- Passenger Presence Sensor Malfunction
- Airbag wiring fault
- Steering column malfunction.
Most often, the electrical wiring is to blame for the malfunction of the active safety system.
Adaptive front lighting system
If this indicator lights up and does not go out while the car is moving, this indicates either a violation of the wiring or a malfunction of the headlight itself. The headlight in a Range Rover car is non-separable and must be changed entirely.
Tire pressure monitoring system
This system is one of the weak links of the Range Rover. The principle of its operation is that it takes readings from each pressure sensor that is installed on all wheels of a Range Rover car, including the spare wheel. Moreover, the pressure in the spare wheel should be more than normal and is 3.5-4.0 atmospheres. And if the pressure in the spare tire is reduced to normal, the system will turn on the pressure control indicator, signaling the need to check the tire pressure. This is the algorithm of the system. In addition, in the pressure monitoring system, the pressure sensor very often fails, which is built into the inflating fitting, which in general is a module of the tire pressure monitoring system.
To replace the pressure sensor, it is necessary to perform tire fitting of the entire wheel, followed by balancing. Therefore, if you give your Range Rover to a car service that does not have a specific specialization in these cars, you must warn the master that you have not an ordinary fitting, but a combination with a pressure sensor and requires careful handling.
DSC dynamic stabilization system on early (pre-2010) Range Rover models
If the dynamic stability indicator flashes while driving, this means that the DSC is working correctly both when the car skids and when slipping, and if the indicator is on constantly, this indicates a malfunction of the system. The dynamic stabilization system is implemented on a programmed algorithm, the algorithm of which is based on the engine management system, automatic gearbox, auto-lock system and other Range Rover systems, and is designed to achieve maximum vehicle stabilization in any road conditions.
Therefore, the inclusion of a malfunction indicator of the dynamic stabilization system is accompanied by the inclusion of other indicators indicating other malfunctions. For example, if the rear differential lock actuator fails on a Range Rover, the DSC malfunction indicator light will be constantly lit. The same will happen if the anti-lock braking system or the adaptive suspension system is faulty. Very often, the cause of any malfunction can be electrical wiring, since the Range Rover car has enough places where the wire insulation can break down and the conductor shorts to ground. Let's say the wire breaks as well.
On a Range Rover with electrically controlled shock absorbers, the stability control fault indicator may come on if the control wires are open or shorted. Moreover, the wires that are connected to the upper supports of the front shock absorbers fail most often.
Dynamic Stability Control DSC on Range Rover models from 2010
The stability control indicator should flash while the vehicle is moving, as this indicates that the system is working properly. Constant illumination of the indicator indicates a malfunction of the system. In modern models of the Range Rover car, an adaptive dynamic stabilization system is used. Unlike traditional systems, the adaptive system also controls the machine in normal modes using an electronically adjustable suspension in the memory of the control unit, which stores data on various road surfaces. The system adapts to any road surface, using the principle of "fuzzy logic". The most common malfunction of the dynamic adaptive stabilization system is a wiring malfunction.

An engine power limit on a Freelander 2 may occur to alert the driver to a problem with the air supply system or the fuel system. This is a general alert and cannot pinpoint the exact location of the problem.
There are many different elements in the fuel and air supply systems that, if they fail, will display the same message "POWER LIMIT" on the instrument panel. The difference may be the behavior of the car. The warning may be on, but the overall dynamics remain. Dynamics can be partially worsened. Or the car does not gain momentum at all and does not develop power. But even this is not enough to make a correct verdict.
