In 2005, the public saw a new generation of this family. IN this case, this is the BMW 3-Series e90, which has changed a lot from the previous generation. In this form, the model was produced until 2008, and after that it was restyled and produced until 2012.
The model has changed a lot, in almost all parts. It also has several body versions: sedan, station wagon, coupe and convertible. In our country, of course, the sedan is the most popular.
Design
Traditionally, car inspection begins with its appearance, which has undergone cardinal changes. The front part is distinguished by numerous reliefs on the hood cover, optical instruments have become narrower and more aggressive. The middle part, as before, is occupied by a stylishly executed radiator grille covered with chrome. The bumper looks interesting with its forms, there are intakes in its lower part air currents. There are also round foglights.
Looking at the BMW 3-Series e90 from the side, we get the opportunity to admire its excellent sports form. The arched parts are moderately inflated. passing by door handles the stamping line looks more pronounced. Even on the bottom of the skirt there is a stamping. The windows are adorned with chrome edging.
The rear part, which is called the stern, has changed significantly. But there are still signs in it that remind drivers of past generations. Forms luggage compartment delight many, especially with their spoiler, designed to improve aerodynamics. Excellent optics has excellent stuffing - it looks cool. The luggage compartment lid is curved, the rear bumper is distinguished by relief forms, there is a pair of pipes at the bottom.
Dimensions:
- length - 4531 mm;
- width - 1817 mm;
- height - 1421 mm;
- wheelbase - 2760 mm;
- clearance - 143 mm.

The manufacturer presented to the attention of the consumer a large number of engines. True, there are somewhat fewer of them than in the previous generation, however, anyone can make a choice. Units are available for both four and six valves.
- The base engine is naturally aspirated engine running on gasoline, the volume of which is 2 liters. Its power is equal to 136 "horses". But the dynamics leaves much to be desired - the car picks up a hundred-kilometer speed in only 10 seconds, the maximum speed limit is 210 kilometers. A car on the highway consumes six liters of fuel, and in urban conditions - up to ten.
- The next version is different increased power(at 20 hp). This made it possible to reduce the acceleration time of the BMW 3-Series e90 by a whole second and increase the speed limit by ten kilometers. But fuel consumption in the city increased by a whole liter, but on the highway it remained the same.
- The next engine also runs on gasoline, but already has six cylinders and a volume of 2.5 liters. It issues 218 Horse power, picking up a hundred-kilometer speed in just 7.5 seconds. Cruising speed is equal to 242 kilometers per hour, the consumption in the city is 13 liters. On the highway, up to seven liters are required for every hundred kilometers.
- Continues the line gasoline internal combustion engines a three-liter unit capable of delivering 272 "horses" and top speed reaching up to two and a half hundred kilometers per hour. The speed of 100 km can be dialed in just over six seconds, the consumption in the city is fourteen liters, and on the highway it does not exceed seven.
- A series of gasoline engines is completed with a three-liter engine equipped with a turbine. It produces 306 hp, the first hundred speed limit dials in five and a half seconds. Naturally, the consumption is increased - 15 liters on city streets, and seven - on the highway.
We should talk a little about diesel bmw motors 3 Series e90. These models are much smaller (only two), but many drivers prefer to operate them.
- The line is opened by an internal combustion engine with a turbine, a two-liter. In eight seconds, he gives out a hundred kilometers per hour, consuming seven liters of fuel in the city, and up to five on the highway.
- Another option is a three-liter six-cylinder version. Consumption is small, only eight liters.
Gearboxes are not so plentiful. Two options are presented to the attention of the consumer - a mechanical version with six speeds or an automatic transmission for the same amount. In most cases, rear-wheel drive, but there are all-wheel drive versions.
The pendant is great. Aluminum chassis in front on two hinges, there are stabilizers roll stability. Rear system more interesting, equipped with five levers on each wheel.
Salon e90
Big changes have taken place here as well. Salon BMW 3-Series e90 continues to be quite modern, is very popular with drivers. Various upholstery options are offered, including genuine leather. The build quality is at a high level.
The front seats are comfortable with little support. side type, electric adjustments, heating system. Behind is a comfortable sofa, which freely accommodates three passengers. Not spacious, but plenty of space. There is an armrest for two cup holders, a ski hatch.
To control the driver, a rather thick three-spoke steering wheel is allocated, which can be adjusted both in height and in reach. It is covered with leather material, equipped with buttons for using the audio system. Stylish dashboard represented by large analog gauges, edged with an impressive chrome finish. There are also several displays that are considered a real on-board computer.
The round dashboard is equipped with a nine-inch display multimedia system, in which, much to the chagrin, there is no navigation system. A little lower are the air deflectors of the BMW 3-Series e90 in the amount of two, and under them there is a climate control unit. It's simple, in the form of a small monitor, has a few buttons and two rotary knobs, but it's pretty easy to use. At the bottom there is a slot for disks, buttons for using the radio station. And at the very bottom are the keys with which the heated seats are adjusted.
There is a small box on the tunnel, behind it is the gearbox selector. Next, a puck and a number of buttons are inserted, with which you can control multimedia equipment. Hand brake mechanical. The volume of the luggage compartment is 460 liters, which is also very good.
Price 3 e90
Today it is not possible to buy this model off the assembly line, because a new generation has been launched. It is possible to easily find such a car on automotive markets used vehicles, and there will be plenty of options for bargaining. average cost the car is seven hundred thousand rubles, the final price is determined by the internal combustion engine installed on the car, the equipment and the options chosen by the consumer. In this case, it is necessary to remember the condition of the machine.
In most cases, standard configurations differed only in motors, but there were also models that had other equipment. The base model was equipped with:
- ABS and ESP systems;
- fabric upholstery;
- full electric package;
- conventional radio;
- air conditioning equipment;
- fog optics.
Those who wanted everything else could buy more, or immediately look for a more expensive model with full equipment. In this case, the consumer received a salon covered with genuine leather, a climate control system, cruise control, electric seat adjustment, which are also equipped with heating, a multimedia display, and xenons in optics.
The BMW 3-Series e90 is actually excellent, many drivers of various ages desire to purchase it. You can buy it for a relatively small age. But it is not recommended to chase inexpensive versions, because their condition is most often simply terrible. Having become the owner of such a car, you will get the opportunity to enjoy the driver's style of driving. And even if you have to sell the car, it will remain in your memory for a long time as one of the chic vehicles.

The “three-ruble note” sedan with the “E90” index turned out to be so successful that in 2008, to a large extent, German experts did not dare to change its design and appearance. We all know that, often, "the best becomes the enemy of the good." For this reason, most likely, updated version The BMW 3 Series has been changed in such a way that at first glance you can’t see the changes, but they still exist ...
First, safety - the basis of the safety concept of the 3-series E90 is a solid body, built using high-strength steel grades and special deformation elements to absorb energy that occurs when the vehicle collides with an obstacle. And optimal protection of passengers will be provided by six airbags, three-point inertial belts safety and head restraints on all seats.
Besides, in standard equipment E90 includes mounts for children ISOFIX seats on rear seats. And the front seats (already in basic configuration) are equipped with active head restraints, which significantly reduce the risk of injury to the cervical spine in a rear-end collision. When hit from behind the electronic unit of the security system in the shortest possible time ensures the movement of the front of the head restraint up to 60 mm forward and up to 40 mm upwards - as a result, the distance to the head is reduced and the effectiveness of the stabilizing protective function of the head restraint is increased. Simply put, the BMW 3 Series 2008 model year became even more secure.
In respect of external differences restyled E90 from " previous model", the following can be noted:
- At the front of the car, the emphasis is on width. On the side, the light edge of the side threshold is now located higher and has acquired more expressive forms. In addition, there are two new expressive lines on the exterior mirrors, which continue the interaction of convex and concave surfaces. By the way, the new mirrors provide increased visibility.
- In the rear part of the body, a sporty and emphasized energetic style is also applied. rear bumper, the trunk lid and lights have taken on a slightly different shape. For example rear lights, consisting of two parts, has now acquired the typical BMW L-shape. LED strips clearance lamps, also add expressiveness. Additional dynamism will be given by the increased rear track.
- New sidewalls, contours of the rear part of the body and the front of the car, thanks to the careful study of details, have become visually wider.
The interior of the updated BMW E90 is in many ways reminiscent of the interior of the 5-series. Among several interior design options, the one that is trimmed with ordinary dark plastic seems to be the most interesting and attractive. But the inserts "under the tree", which are designed to give the interior solidity, seem unnecessarily pretentious. Interior designers say that they have applied a modern concept of convex-concave surfaces, aesthetics and sporty elegance in a techno style.
Significant, from a design point of view, detail Salon BMW Series 3 is an 8.8-inch display that is larger than any other car's graphical interfaces. Thanks to high resolution The display provides a rich display of graphics with fine detail. The menu structure, in comparison with the previous version, greatly facilitates the search for the desired functions.
This huge display is integral part multimedia system iDrive, as well as navigation system.
By the way, the Professional navigation system includes a built-in 80 GB hard drive, which provides instant access to the translated digital format cartographic material. Of course, in addition to maps, thousands of mp3s can be stored on this disk.
And most importantly - the "troika" 2008 model year, for the first time in the history of the automotive industry, due to the ConnectedDrive system can provide unlimited access to the Internet. Only here, you can use it only in stationary car. Data transfer is carried out using EDGE technologies(Enhanced Data Rates for GSM Evolution), which, unlike UMTS, covers large areas and works three times faster than the standard mobile communications GPRS.
Of course the Internet modern world- a thing is important, but for a car, other characteristics are considered the most important, the most important of which is the engine. In the case of the BMW 3-series, the most interesting is the new 330d 6-cylinder diesel engine, which, of course, works according to the EfficientDynamics concept. By the way, in terms of dynamics, this three-liter all-aluminum engine is not much inferior to the most powerful gasoline engines. See for yourself: maximum power at 245 hp the new diesel develops at a speed of 4000 min-1. And the maximum torque of 520 Nm is already achieved at 1750–3000 min-1; acceleration to 100 km/h takes just 6.1 seconds, and the top speed is electronically limited to 250 km/h.
You might think that you will have to pay for such dynamics with incredible fuel consumption? - not at all. Average consumption diesel fuel is - 5.7 liters per 100 kilometers. Of course, if you drive dynamically, the consumption will exceed this value. But, in any case, the result achieved in BMW should be recognized as outstanding.
As for the chassis of the updated E90, it still remains one of the most advanced. The rear suspension uses a five-link design adapted to the requirements of engines with high power and torque. At the rear, a double-articulated suspension is used with traction extensions on suspension struts with anti-roll bar, made mainly of aluminium. Standard equipment includes electromechanical steering with a built-in Servotronic function that regulates the efficiency of the hydraulic booster depending on the speed. Active steering is available as an option, which adapts gear ratio steering gear to the current speed.
Prices. In 2008 year bmw 3-series in minimum configuration will cost ~ 978,000 rubles. The cost of the E90 with the most powerful engine and with all-wheel drive will be ~ 1,875,000 rubles.
BMW E90- an automobile platform on which the fifth generation of the 3rd bmw series. The start of production of the e90 sedan is 2005. Station wagon (E91), coupe (E92) and convertible (E93) were launched at the end of 2006. The release continued in 2007, 2008, 2009, 2010, 2011, 2012 and 2013. During this time, the car has been one restyling. We represent general information O bmw fuse box e90 for the above models.
On different models, the list of fuse locations may vary slightly, we present diagrams of the most common BMW modifications 3-series.
It is located in the glove box (also called the glove box). To access, unscrew the two latches and remove the protective cover. If you have trouble with this, watch the video at the end of the article.
On reverse side protective cover there should be a brochure with your location of fuses and relays. She looks like this.

Maintenance and operation manual
Do you want to know more information about bmw e90, read the instruction manual: ""
A distinctive feature of all cars brand bmw is their reliability. Even for modern technically complex modifications, stuffed with electronics, durability and wear resistance are characteristic. However, this does not mean that Bavarian cars are absolutely impeccable. They also have weaknesses, and there are many of them. Consider typical bmw problems on the example of the sedan of the third series E90, produced in the period from 2005 to 2012.
Exterior BMW sedan 3 E90 is elegant and moderately aggressive.
As for the appearance of these cars, we can confidently say that their design will not become obsolete for a long time. At the same time, thanks to the “correct” metal, which is highly resistant to corrosion, the body will live without problems until the moment when appearance cars will go out of fashion. It is also important to note the thick layer of durable paint, which retains its shine for a long time and does not wear out during washes.
The BMW 3 E90 sedan was developed on the same platform as the 1 series cars.
The headlights can be considered the main drawback of the appearance of pre-styling cars produced in the period from 2005 to 2008. Without visible reasons their glasses crack, and this problem is typical even for headlights equipped with low-temperature xenon lamps. Meanwhile, the price of one headlight in complete set is 700 euros. Cheaper disadvantages include such examples as the washer hose (12 euros), which tends to burst at the most inopportune moment, and the telescopic nozzle drive (50 euros).
"Sick" place BMW 3 E90 - headlights prone to cracking.
Widespread use in winter period chemical reagents often leads to the failure of car electrics. For example, in major cities cases have been repeatedly recorded when in just 2-3 years the positive wire of the fuse box completely rotted away. At the same time, it should be said that in order to “cure” a car, replacing only the wires is not enough - you need to change the entire JunctionBox, and this is no less than 400 euros. Corrosion also causes "souring" of the moving elements of the wiper mechanism (300 euros).
After six to eight years of operation, it is often necessary to lubricate the bearings of the heater motor. The need for this is very easy to determine - when running dry, they make an unpleasant whistling sound. But this is half the trouble. Much worse if on machines with dual zone climate control from the passenger seat only starts to blow cold air. The reason for this is the failure of the heater valves or the auxiliary water pump. Their replacement will cost 300 and 170 euros respectively.
Salon BMW 3 E90 looks great even after several years of operation.
Seat heating out of order? The cost of repair depends on the type of seat. Heating elements for ordinary chairs are quite budgetary - 18 euros for a pillow and 60 for a backrest. Worse, if installed in the cabin sports seats, since in them the heating elements are built into the upholstery and change only as a set with it, and this is completely different money - from 600 to 1000 euros, depending on the type of seat material.
In general, the electrics of the BMW 3 are different. stable job, although here it was not without a fly in the ointment, which was the servomotor (220 euros) of the Valvetronic throttleless system, which rotates the eccentric shaft that regulates the stroke intake valves. As practice shows, it is enough for no more than 50 thousand km. As for other components, replacements ahead of time may require only ignition coils (42 euros). Generators successfully "live" for more than 200 thousand km. And by this time, engines often require repairs.
Under BMW hood 3 E90 the apple has nowhere to fall.
The appearance of the "treshka" was marked by the cessation of production of the famous "slab" - the engines of the "M-fiftieth" series, which rightfully deserved the title the best motor among all Bavarian powertrains. New cars are equipped with an N52 engine with a bimetallic cylinder block. Inner part The BC is made of aluminum alloy, the outer one is made of magnesium. This was done to reduce the weight of the engine and the car as a whole, while increasing its power and efficiency, which was achieved. However, the reliability of the N-series engines leaves much to be desired. It is worth noting that it is carried out in many service stations serving Bavarian cars.
The bimetallic motor of the BMW 3 E90 is not very reliable.
First of all, it is worth noting the increased oil consumption. And the 2.5-liter power unit especially distinguished itself in this indicator. His oil consumption can be up to 1 liter per 1000 km. The main reason for this is the excessively thin rings and poor shape of the pistons, which ultimately leads to wear of the cylinder-piston group and repairs, which, according to the most conservative estimates, will cost 2,000 euros. By the way, it would be useful to note that about a quarter of all cars produced in the series are equipped with a 2.5-liter engine.
For gasoline engines relatively short service life valve stem seals, which does not add fuel economy to cars in oil consumption. It is worth noting the rather strange decision of the Bavarian designers to abandon the usual mechanical probes. Now oil control is carried out only with the help of electronic sensor, displaying readings on the on-board computer. At the same time, it should be noted that it does not suffer from excessive accuracy, and the data update is not fast enough.
Information about the oil level is displayed on the on-board computer.
After 60-70 thousand kilometers, the crankcase ventilation system often fails. As a rule, the cause of this is coking of plastic pipelines (100 euros), as well as breakage of the oil separator membrane (90 euros). If you do not contact the service in a timely manner, then the result is the failure of the valve hydraulic bearings. They are quite affordable (only 10 euros per unit), but keep in mind that there are 24 of them.
On my own Vacuum pump quite reliable and often serves up to 200 thousand km. However, after 110-120 thousand kilometers, you should carefully look to see if there are oil streaks around. If so, then it's time to change the gasket.
No less attention should be paid to the cooling system, especially when it comes to long in-line “sixes”, which are very sensitive to elevated temperatures. It is worth prophylactically cleaning the gap between the radiators at least once every two years. At the same time, you need to know that they themselves, thanks to small honeycombs, are prone to clogging. Prevention is required and expansion tank, the cover (15 euros) of which should be changed 1 time for 50-60 thousand km. However, there are also positive aspects: for example, the problems with the fan characteristic of the M-series have disappeared, since not too robust construction with a thermal coupling was replaced with an electric one. Besides, in gasoline engines the timing chain can be considered eternal. But in diesel modifications, it is she who presents a lot of problems.
In fairness, it should be noted that this is not true for all diesels, but only for the infamous four-cylinder engine of the N47 series. After 80-120 thousand kilometers, its chain can be so weakened that it either breaks or jumps over one or two teeth of the drive sprocket. The gas distribution mechanism is located extremely unsuccessfully - in the rear of the block, which makes visual control difficult. Nevertheless, it is still necessary to monitor the condition of the chain, since if it jumps, the repair will cost 1500-2000 euros, and the chain break is “cured” only by a complete replacement power unit, and this is already an amount of at least 10,000 euros.
But the transmission BMW cars 3 is almost perfect. All-wheel drive xDrive raises no questions at all. The six-speed "mechanics" is also very reliable, the maximum may be required to replace the clutch (300-400 euros) after 200 thousand kilometers.
Connecting the rear axle gearbox to the cardan shaft.
But the six-speed automatic ZF - although common, but not the most The best decision. At approximately 120-150 thousand kilometers, the box may require the replacement of gaskets and seals, which will cost 250-300 euros. If the mileage is greater, then the risk group should include the electronic-hydraulic control unit, clutches, torque converter. And then the repair will result in a tidy sum - from 1500 to 3000 euros.
Not by myself strong point BMW 3 is suspension. On powerful versions the car needs to be controlled rear axle. If light clicks are heard during intensive acceleration, urgently go to the service! Flange nut needs to be changed cardan shaft. Otherwise, during intensive acceleration, the cardan may fall off. As for other problems, it is worth noting the stabilizer struts, which require replacement every 30-40 thousand km. And for the first versions of the car, released before the restyling of 2008, it is necessary to change not only the racks, but also their bushings. In addition, after 100 thousand kilometers, it is often necessary to replace the front and rear shock absorbers(200-250 euros respectively) and front suspension arms (120 euros apiece). Levers rear suspension they last a little longer - 120-140 thousand km.
It is noteworthy that the X-versions of the "treshka" suspension has a shorter service life than the rear-wheel drive modifications. Meanwhile, the car previous versions bodies, for example, E46, all-wheel drive options were stronger. This is explained by the fact that in order to reduce the weight of the machine, the steel levers were replaced with aluminum ones. In general, the E90 even has front wheel bearings that change along with the hub (210 euros), with rear wheel drive serve up to 200 thousand kilometers, and with a full one, about two times less.
Front design bmw suspensions 3 E90 is identical to the suspension of the car of the first series.
Another problem of the E90 sedan can be considered heavily loaded brakes. They are used not only for their main purpose, but also as a component ESP systems. As a result brake discs often they are not erased after the usual 70-80 thousand km, but already by 50 thousand km. Regardless of the version of the car, it is necessary to carefully monitor the calipers - due to work in high temperature regime they are often covered with a caked crust of dirt, as a result of which brake pads are starting to eat. At the same time from high temperatures hub flanges quickly oxidize, after which it is quite difficult to remove the wheels.
It is worth noting relatively high reliability steering rack, both conventional (1400 euros) and ActiveSteering (2000 euros). Therefore, if after 100 thousand kilometers a backlash appears, do not rush to change the steering rack - it is quite possible that the problem is solved by replacing the steering shaft cross, which costs much less (210 euros). But the power steering pump (450 euros) requires close attention after 150-160 thousand km. If the assembly is not replaced in time, the chips will scatter throughout the system, and this will lead to the need to replace the rail.
As you know, most premium automakers use thin marketing ploy- expands the lineup by creating cars in the lowest price category. And such a step turned out to be quite justified - the number of people wishing to become owners of premium cars in a low price segment is constantly growing. A worthy alternative to buying new premium, although relatively inexpensive models could be buying used premium car, the initial cost of which a few years ago for many motorists was unbearable.
We decided to consider such a purchase option using the example of the BMW 3 Series in the E90 body, the production of which was discontinued in 2009. Among vehicles aged 4 to 8 years secondary market this model is the most common. As for the cost of such a car, the price range can be very significant - from 450,000 to 1,500,000 rubles and depends on the year of manufacture, the condition of the car, its mileage and equipment, as well as the type of sale (urgent / not urgent).
As an average used BMW, we chose a 2.0-liter BMW 318 on the "automatic". Its 136 horsepower with a peak torque of 180 Nm can accelerate the sedan to the first "hundred" in less than 11 seconds and provide a top speed of 208 kilometers per hour. According to passport data, the fuel consumption of this modification in the city and on the highway is 11.1 and 5.9 liters, respectively. By the way, according to the reviews of many owners, passport data on fuel consumption are very close to real indicators.
The first thing that almost every potential buyer of a used BMW starts with is to study the cost of maintaining it and possible breakdowns. Let's try to collect the most common "diseases" of the BMW 3 Series in the back of the E90 and give some recommendations. As a rule, with proper maintenance, four-cylinder BMW engines up to 100,000 kilometers do not cause any difficulties. With a more "solid" mileage, it often occurs increased consumption oil, the cause of which is the loss of elasticity of valve seals (valve seals).
The fact is that due to considerations of environmental friendliness and economy (although not essential), the operating temperature of the new BMW engines is in the range of 120 ° C and under such conditions the rubber of the valve stem seals cannot retain its original properties for a long time. It is precisely because of the high operating temperature engine, do not neglect such a procedure as washing the radiator with removing it from the car. Although there is no such procedure in official regulations MOT, the conditions of Russian operation with autumn-spring mud, winter salt and summer dust make it extremely necessary. It is impossible to clean the radiator without removing it from the car, so sooner or later it can cause “chronic” overheating, which will significantly reduce the life of the motor.
In addition, on vehicles with high mileage the cause of overheating can also be a controlled thermostat, the resource of which ends just after 100,000 km. The fact is that, unlike traditional thermostats, the design of a controlled thermostat has an additional heating element in the form of a spiral, which is electronically controlled and forcibly opens a large cooling circle, thereby preventing the motor from overheating. It is almost impossible to identify the moment when the spiral burns out, and the engine will constantly overheat.
The next pitfall is official recommendations for service intervals, which can reach 25,000 km. It should be understood that such recommendations were developed taking into account the ideal operating conditions of the car. In real conditions, this interval should be at least halved. The next "nuisance" in four-cylinder BMW engines after a run of 100,000 km is the stretching of the gas distribution chain, which entails the "care" of the valve timing, which in turn causes a drop in power and unstable work at idle. Six-cylinder engines do not have this problem due to better balance. Another item to check when buying a used BMW with a gasoline engine is the alternator overrunning clutch. A worn clutch can jam and turn the timing sprocket. N57 diesel engines do not have this “disease”.
Do not forget to diagnose the operation of Vanos. If the previous owner does not change the oil in time, this unit may present such a malfunction as “mechanical jamming”. When choosing a more powerful modification with six-cylinder engine N52 in addition to checking Vanos, you need to pay attention to the condition of the timing chain and the Valvotronic system.
Despite their efficiency, modern four-cylinder BMW gasoline engines turned out to be an order of magnitude more “capricious” than their predecessors, so when choosing a used “troika”, it makes sense to give preference to six-cylinder or diesel modifications. Diesel versions The BMW 3 Series in the E90 body was equipped with 2.0- and 3.0-liter N47 and N57 engines, which, despite the shorter service interval, an order of magnitude more reliable than gasoline "brothers", but by 200,000 km on a 3.0-liter unit, it is almost guaranteed that the turbine and torsional vibration damper will need to be replaced.
As for the choice of the type of transmission, today the vast majority of motorists incline their choice in favor of the “automatic”, while just a few years ago this option scared many away due to expensive repairs of this unit. Today we can say with certainty that this judgment was erroneous. The E90 was equipped with a reliable ZF six-speed automatic, which, with proper maintenance, takes care of more than 200,000 km without any problems.
The key to long trouble-free operation of the "machine" is the serviceability of the cooling system, which is "tied" to the engine cooling system. When overheated, the oil in the box heats up to 130-140 ° C and loses its properties. In this case, intensive wear of the friction clutches occurs. But the most interesting thing is that the box does not show any signs of malfunction. The thing is that when the friction clutches wear out, abrasive particles get into the oil, making it thicker. This is the "secret" of the box failure after a "harmless" oil change. Therefore, before buying, we strongly recommend that you computer diagnostics box, which will also show the temperature of the oil.
In terms of electronics, the “troika” in the back of the E90 can present a problem with the front power distribution box, which is located under the glove box, as well as the battery wire leading to it. You should also pay attention to the operation of the fan of the control electronics compartment, a malfunction of which can “burn out” the electronic control unit.
In general, when choosing the “right” copy of the BMW 3 Series in the back of the E90, the car is guaranteed to give its new owner driving pleasure and premium status, and the cost of acquiring it and eliminating small “jambs” will not exceed the cost of a new budget car.
