Which Audi A4 Engine is the Most Reliable. How to buy the right Audi A4 B7 with mileage: extra power ... happens Types of Audi A4 engines

Powerful and at the same time economical engines provide impressive driving performance of the Audi A4 in all its variants: sedan, Avant and all-wheel drive quattro. This fully applies to the convertible (since 2002). The engines are more than compliant with the strict European emission standard EU 4. In the six-cylinder engine, for example, this is achieved by two additional high-density ceramic catalytic converters located near the engine with three layers of precious metal, as well as two main catalytic converters, which are located at the bottom of the body.

Developing power units for the new generation of "fours", the manufacturer has worked hard to improve internal combustion engines. Their inventor, Otto, would certainly have liked it. For the first time in this series, two completely new gasoline engines with an aluminum crankcase are used: a 96 kW (130 hp) four-cylinder in-line engine with a displacement of 2.0 liters and a 162 kW (220 hp) six-cylinder V-twin engine. with a working volume of 3.0 liters. The range of petrol engines is complemented by a proven 110 kW (150 hp) Turbo engine with 1.8 l displacement and a revised 75 kW (102 hp) engine with 1.6 liter displacement.

The Avant large-capacity variant before the premiere of the new model in July 2001 was equipped with 2.4 l (165 hp) and 2.8 l (193 hp) engines. Now, the new A4 Avant uses the same petrol engines as the sedans that received them in October 2000, meaning the Avant comes with a new 1.6L engine.

With the exception of this 1.6-litre base engine, Audi relies on five-valve technology to speed up gas exchange in petrol engines. Two intake and three exhaust valves are designed to provide better gas flow. It is clear that more gas mixture passes through three valves at the same time than through two or one valve. Cylinder filling per intake stroke is greatly improved.

3.0L ASN 6-cylinder V-engine
If we ignore the main concept, i.e. with cylinder banks at 90" to each other and identical cylinder bores, the new best engine uses few components from the previous 2.8L engine. Six-cylinder, V-twin, five-valve engine accelerates the A4 front-wheel drive sedan with a five-speed manual transmission from 0 to 100 km/h in 6.9 seconds, top speed is 245 km/h, and average fuel consumption for this version is only 9.5 liters.

The most important innovations in this engine are an aluminum cylinder block (due to this, the engine weighs only 163 kg), lighter pistons, a balance shaft, a continuously variable intake camshaft, a variable exhaust camshaft, a new two-stage variable geometry gas pipeline and a Bosch-engine control unit. Motronic ME 7.1.1 with electronic accelerator pedal.

The intake camshaft can be continuously adjusted up to 42" in the direction of early ignition. On the exhaust side, if necessary, the camshaft can be adjusted by 22 * ​​in the direction of late ignition. Already at 1900 rpm, the system sets the maximum overlap, this allows you to achieve the maximum possible torque The maximum torque of 300 Nm in this case is generated already at 3200 rpm.In the range from 2200 to 5200 rpm, 90% of the maximum torque is provided.

Along with ingenious camshaft adjustment, the ASN engine features a newly designed two-stage variable geometry intake manifold. Starting from 4200 rpm, the resonant intake manifold switches to a short path. Maximum power of 162 kW (220 hp) is provided at 6300 rpm.

2.0L ALT engine

As the second newcomer to the range of petrol engines, Audi has introduced an in-line engine with a displacement of 1984 cm3. This five-valve engine with an aluminum cylinder block and counterbalance shafts for improved running accelerates the A4 Sedan from 0 to 100 km/h, also in less than 10 seconds. The maximum speed is 212 km / h. Considering that the fuel consumption is only 7.9 liters, it can be argued that this engine will compete with other power units. Testers commend this engine for revving very well, and revs are not accompanied by unpleasant vibrations.

Key technical innovations highlighted by the manufacturer include continuous intake camshaft adjustment to achieve optimal engine filling, a program-controlled cooling system to increase efficiency, a new two-stage intake gas line with variable duct geometry to provide more torque and high power, as well as balancing shafts to improve engine performance.

2.0L FSI engine with direct petrol injection

The 2.0-litre four-cylinder engine was chosen by Audi to move to a new generation of gasoline direct injection (FSI) engines. The cylinder block and dimensions of the FSI engine correspond to those of a conventional engine with the same displacement. New is only that it has a fuel injection system with a common fuel line and a single-plunger injection pump. In the cylinder head, unlike Audi engines with injection into the intake manifold, there are not five, but four valves. This freed up space for the injector, which dispenses fuel with millisecond precision at an injection pressure of 110 bar. The four-valve cylinder head has a gas distribution mechanism with valve drive through rocker arms and roller tappets. The variable geometry inlet gas line in the FSI engine is also two-stage, that is, the intake tract can have different lengths for high and low speeds. The constant adjustment of the intake camshaft in this engine also ensures proper control of the valve opening times.

The MSI engine also uses two catalytic converters to clean the exhaust gases. Behind the exhaust manifold near the engine is a three-way staged catalytic converter, and in the lower part of the body is a storage catalytic converter, in which nitrogen oxides are accumulated and converted. The storage converter is designed to meet the special requirements associated with the characteristics of a direct injection engine. This neutralizer binds nitrogen oxides in the barium layer.

1.8L AVJ turbocharged engine
The 1.8-litre turbocharged four-cylinder engine, which is the classic engine of the previous generation, has also been taken into account in the creation of the new A4 models. The engine has been tested a thousand times. This unit is valued for its high torque (210 Nm), which, thanks to the turbocharger, is already created at low speeds (1750 min-1). Up to 4600 rpm this moment does not change. In this way, maximum torque is ensured throughout the entire rev range, which is mainly used during driving. This power development is usually found only in engines with large displacement.

The front-wheel drive A4 1.8T with manual shifting consumes only 8.2 liters of Super gasoline (unleaded gasoline with an octane rating of 95) per 100 km. Acceleration from 0 to 100 km/h with this engine is achieved in just 8.9 seconds. The maximum speed is 222 km/h.

ALZ engine with a working volume of 1.6 liters

A large amount of mental labor was required to create the base engine with a displacement of 1.6 liters. Thanks to a new low-friction roller rocker valve train and the fine grinding of many components, the two-valve engine is more powerful and less polluting. The four-cylinder in-line engine has an overhead camshaft, the maximum power is 102 hp and the maximum speed is 190 km/h. As with other motors controlled by Bosch Motronic ME, ME 7 is now used for electronic motor control. Earlier ALZ models are equipped with the proven Simos 3.4 from Siemens.

Engine parts

• Cylinder block. Moving parts are placed in the cylinder block. In addition, the cylinder block serves as a support for such units as the generator, starter and ignition system.
• Cylinder head. The cylinder head covers the cylinders from above. It contains intake and exhaust passages, water passages, valve seats, bearings and guides for valve timing parts, as well as spark plug threads and a combustion chamber. The gasket between the metal surfaces of the cylinder head and the cylinder block prevents air and coolant from entering the cylinders.
• Cylinders. The cylinders together with the cylinder head form a combustion chamber (working cavity). They are smoothly ground (honed) and precisely matched to the diameter of the pistons. Cooling is provided by water that flows through channels that are present in the cylinder wall.
• Pistons. The pistons take the combustion pressure and transfer it through the connecting rods to the crankshaft. The main parts of the piston include the piston crown, the piston ring belt and the piston pin boss. The two upper piston rings (O-rings) prevent gas from escaping from the combustion chamber into the cylinder block. The lower ring (oil scraper ring) drains excess lubricating oil from the cylinder wall back into the oil pan.
• Connecting rods. The connecting rod connects the piston to the crankshaft. Connecting rod components: connecting rod head (covers the piston pin), connecting rod rod, lower connecting rod head and connecting rod cap (covers the connecting rod journal).
• Crankshaft. Converts the up and down movement of the pistons into rotational movement. Crankshaft parts: main journals (for bearing on the cylinder block), connecting rod journals, crankshaft cheeks (connect the connecting rod journals to the main journals).
• Valves. Fresh gas enters the cylinders through the intake valves, and exhaust gases are released into the exhaust pipe through the exhaust valves. The set of all the parts that are involved in opening and closing the valves is called the valve mechanism.
• Camshaft. The camshaft opens and closes the valves at the appropriate time. Each valve is cam driven via a poppet or roller rocker. The camshaft is driven by
• Toothed belt from the crankshaft.

Audi A4 engines, these are modern, powerful gasoline and diesel power units. In Russia, customers are offered gasoline engines of the TFSI series with a working volume of 1.8, 2.0 and 3 liters. 2 and 3 liter TDI diesel powertrains are also available. At the same time, 1.8 TFSI in the basic version has 120 hp, in a more powerful version it already has 170 horsepower. The same story with the 2-liter diesel engine Audi A4 is outstanding in different versions of 150 or 177 hp.

TFSI A4 engines of the same volume can easily have completely different capacities. The reason is not in the design of the motor or the software of the electronic control unit, mainly the power depends on the turbo. More precisely, from the performance of the turbine, the more air the turbine is able to “inflate”, the greater the power of the Audi A4 engine. Often, two turbines are attached to the engine, in which case the motor produces maximum power. The same principle works in the case of the Audi A4 diesel engines.

First, let's talk about gasoline engines Audi A4 TFSI working volume of 1.8 and 2 liters, which are almost identical in design. The only difference is the piston stroke, which is 84.1 mm in the 1.8 TFSI and 92.8 mm in the 2-liter. The cylinder diameter of both engines is the same 82.5 mm. This is an in-line 4-cylinder, 16-valve engine with a cast-iron cylinder block, an aluminum cylinder head, two camshafts, a timing chain drive, a variable valve timing system for intake and exhaust valves.

Combined fuel injection is carried out both into the manifold and directly into the combustion chamber. The in-line four-cylinder gasoline engine of the Audi A4 has a turbocharger with an intercooler. Of the features, the Audi valvelift system (AVS) valve lift control system can be noted. The valve mechanism of the power unit has hydraulic compensators.

Audi A4 3.0 TFSI engine, this is already a 6-cylinder V-shaped engine. There are 24 valves per 6 cylinders. The double cylinder head uses 4 camshafts. A chain is used as a timing drive, and not one or two, but much more. You can see this image below.

If the Audi A4 engines with a volume of 1.8 and 2 liters have turbines, then the V6 has a mechanical supercharger installed, it is installed in the cylinder camber zone, between the two parts of the block head. The use of a supercharger avoids the “turbo lag” effect, since the air supply is continuous, there is no need for strong cooling of the charge air. Plus the compact design and durability of the mechanical compressor. Actually, by installing more efficient compressors, you can increase the power of the Audi A4 engine.

As for the Audi A4 diesel engines with a working volume of 2 liters, these power units have fuel injection directly into the combustion chamber and turbine. Pretty economical diesel Audi A4 2.0 TDI with a common rail injection system, has a large torque of 320 Nm. But if the Audi A4 gasoline engines have a timing chain drive, then the diesel has a belt.

cylinder head diesel engine Audi A4 2.0l TDI with common rail injection system is made of aluminum and has a design with a cross-flow of gases, two intake and two exhaust valves per cylinder. Valves are located vertically and are directed downwards. Two camshafts are located on top and are connected by a gear train with a spur gear that has a built-in gap compensator between the gear teeth. The timing is driven from the crankshaft using a toothed belt and a toothed pulley on the exhaust camshaft. The valves are actuated by low friction roller levers equipped with hydraulic compensators.

This motor uses an interesting timing drive scheme. The belt synchronizes the rotation of one camshaft with the crankshaft. And the second camshaft is synchronized with the first due to the gears on the camshafts. Further more detailed Specifications Audi A4 2.0 TDI

Audi A4 diesel power units are characterized by high torque with minimal fuel consumption. The 3-liter turbodiesel produces 500 Nm of torque and accelerates the car to hundreds in 5.9 seconds, while consuming less than 6 liters of diesel fuel in mixed mode. Of course, the maintenance and especially the repair of this unit is a very expensive undertaking, but you have to pay for such dynamics.

Nobody argues with the fact that the body and the base of the A4 in the back of the 8E were very progressive and had a good margin for modernization. But, unfortunately, electronics at the turn of the century did not age quickly, but very quickly. Progressed engine management systems, stabilization systems, steering, cruise control, lighting and passive safety. And progress in various service functions of climate control, multimedia and navigation, vision improvement systems and others generally rushed at a breakneck pace - in this area, embedded systems became obsolete within a year or two after the release of a new car. In such a situation, Audi engineers decided on a global redesign, hardly less laborious than redesigning the car, but left the basic design intact. The motors, on the other hand, underwent modernization in connection with the introduction of Euro-4 environmental standards, but at the same time, basically, they remained the same in design.

The body frame, transmission and suspension here also remained the same as their predecessor. They didn’t change manual gearboxes - they don’t look for good from good. They brought to mind the variator, which on the previous model caused massive criticism, new ZF automatic transmissions were installed on all-wheel drive vehicles, and they switched to a more progressive six-speed ZF 6HP19 automatic transmission. Almost all other elements of the transmission have changed very little, as well as the suspension. Cars of the first years of production and with matching engines generally have the same components as the previous "four", except for some that are responsible for tuning the handling. And this approach turned out to be very good: the time-tested and modified components on the new machine are among the most reliable and trouble-free. And, by the way, do not look at the relatively short period of release of the model - after the end of production under the Audi brand in 2008, the car was sold as the Seat Exeo until 2013, however, in simplified trim levels. Production was completely transferred to Spain, while the car was deprived of automatic transmissions and engines more powerful than 2.0T. By the way, many Seat parts will fit Audi, and the price for them is often a little lower.

General layout problems migrated unchanged from their predecessor. But in general, the car can be considered very successful. Complex and expensive suspensions for the B7 exit no longer had any special problems with mileage and were not a problem. The electronic filling has become more complex and expensive, but the total number of problems with it has hardly increased. Even the A4 variator was already fine-tuned by the release of this generation, and by the end of the model’s release it could be considered one of the most problem-free automatic transmissions of this brand, especially against the backdrop of the beginning problems with DSG boxes in Passat and other cars of the concern with a transverse engine. Well, now let's talk about the features of the machine in more detail.

Engines

Motors 1.6, 1.8T and 2.0 MPI are the same here as on their predecessor. But the 2.0 TFSI engine that appeared, with a capacity of 170-220 hp, is new here. It could be found on cars in the old body of the last year of manufacture, but their number is extremely small. On the B7, this is already one of the most common engines. The transition to turbocharged direct injection allowed a slight increase in power and torque compared to 1.8T, but the car received a whole set of problems with 2.0 FSI engines in the form of capricious and expensive injection equipment, a very unreliable piston with constantly coked piston rings, clogged crankcase ventilation and firmware problems. We figured out the firmware quickly enough, but no one was in a hurry to solve the rest of the troubles. After several replacements, the piston engines became less hungry for oil, the crankcase ventilation was also changed, and by the end of the model's release, the motor already seemed to be the standard of reliability against the background of newcomers. But the engines turned out to have the highest potential for boosting, it was not without reason that this engine was put on the Golf R even after this line of engines had already been discontinued. New 3.2 FSI with 255 hp no better than turbocharged ones in terms of reliability; in this generation, the brand's engines were not at all lucky. Here and "maslozhor", and overheating, and failures of the power system. But the most unpleasant surprise was with the piston group of this aluminum engine and problems with the timing chain. The cylinders here are aluminum, which means that they are easy to damage. And due to a miscalculation in the design of the piston group and an abundance of soot, such motors regularly “lift up”. About repair methods for such equipment, and believe me, there are no inexpensive ways, just as there is no chance for a long life of such a problematic motor.

At the end of the existence of the model, a recall campaign was carried out on the market: in an attempt to reduce the "dump" of the motors, the thermostat was changed to a less hot one. The effectiveness of this measure turned out to be small, but still it can help motors that are operated mainly in urban areas. Otherwise, we can advise you to change the oil more often, use ester and PAO compositions, and change air filters more often. And the 4.2 engine is new here - unlike the engines of the ASG / AQJ / ANK series, completely new BBK / BNS were installed here. Their timing chain mechanism looks like a work of art, the mass is less than 200 kg, the highest power, but ... But you should not take the Audi S4 or RS4: all the problems of 3.2 FSI are here, besides, the cylinder block turned out to be frankly weak.

Fortunately, RS buyers are usually ready for a short resource and high cost of maintaining such a “lighter”, which cannot be said about the owners of the huge top-end Q7 crossover, on which these engines were also installed. Perhaps this is one of the shortest-lived series of engines of the German concern - there was simply nothing to upgrade there, and after three years of the announcement, the production of cars with these engines was simply curtailed.

If you need high power, then your choice is tuning 2.0 TFSI or even 1.8T, and if you want out of the box, then the previous S4, released before 2004 or the next one, after 2008. Pay attention to what service intervals operated the car. If the owner sincerely believed that LongLife makes it possible not to change the oil for 15-20 thousand kilometers, then the condition of even 1.8T and atmospheric 2.0 will be very poor, and subsequent repairs will be expensive. Diesel engines have changed little: there are exactly the same 1.9 TDI and 2.0 that were on, and others. 2.7 and 3.0 diesel are also considered successful engines. The main problems include expensive piezo injectors with a limited resource and a tendency to fuel leakage, which can lead to piston melting, for example. The motor also has a complex timing mechanism with several tensioners, it can unexpectedly fail at the most inopportune moment and is extremely expensive to repair. In addition to the "traditional" diesel problems with fuel equipment and EGR, it is worth remembering the poor lubrication of the camshaft on 2.0 TDI with unit injectors. 2.5 TDI engines have no problems with injectors, but it is not less troublesome from this. The older design is often happy with problems with lubrication pressure and even problems with the piston group.

transmissions

As with the previous A4, manual transmissions are no problem, as is the transmission itself as a whole. Even all-wheel drive Quattros are no less reliable, because there are no clutches and other transmission electronics. CVTs are also very resistant, although they have a limited chain resource (about 100-150 thousand kilometers) and will require expensive repairs if they are not replaced on time or if the drive cones are damaged by towing the car. CVTs also don't like harsh driving style and dirty oil and can be very expensive if not used properly. But with careful operation and replacing the chain on time, they can cover all 300 or more thousand kilometers without annoying minor problems. All-wheel drive versions of the Quattro were equipped with a new six-speed ZF 6HP19 automatic transmission. “New” here is not at all a synonym for “best”. Experts note a smaller resource of box bushings, torque converter, friction clutches, solenoids and valve body. This is due to an attempt to get closer in terms of efficiency and clarity of work to DSG boxes and much more stringent settings for the electronic part. This means that there are much greater shock loads, slippage of friction clutches even in standard operation and a large thermal load. The hydraulics and electronics unit here finally took shape in a “mechatronic” with a very dense layout, but still repairable. For owners, all this means that the gearbox on a car that was operated with a trailer or just a “racer” will already be in a pre-heart attack condition and may require expensive repairs even with “just over 100” runs. However, even for cars that are operated quietly, with runs closer to 150-200 thousand kilometers, the repair will be cheaper, but also serious - at least with the repair of the gas turbine engine and the bulkhead of the box itself to replace worn bushings and VFS solenoids.

Unfortunately, in this generation of machines, the variator turned out to be stronger than the “classic machine”. Audi's service policy also contributed to this in many respects - after all, the oil in automatic transmissions did not officially change, and instead of the usual ATP, the manufacturer allowed pouring only extremely expensive branded oil, the cost of which discouraged any service procedures. Of course, in fact, you can pour the same oil there as in other ZF machines, and you don’t need to buy a “branded” one at 3 thousand rubles per liter. By the way, these automatic transmissions on BMW proved to be somewhat better - including, perhaps, due to the mandatory replacement of fluids.

Chassis

The suspensions of the car have changed little compared to the previous A4, and in general the problem is the same - the high cost of quality components, the presence of many levers and the need for a responsible and complete suspension repair every time. She does not tolerate “bitching” and requires a complete check and diagnostics in advance, and not when something has already started knocking. First of all, both ball bearings in the front and lower arms in the front and rear suspensions traditionally fail, but with the right approach and careful operation, the suspensions will cover 100-150 thousand kilometers without a complete overhaul, with the replacement of only the most wear parts. As on its predecessor, there is a conventional steering rack and a conventional power steering pump. But the proven design is far from eternal: with runs over a hundred thousand, hydraulic leaks often begin, and when operating on bad roads, the rake will also knock. By the way, this is an occasion to carefully examine the suspension: perhaps it will also not be in the best condition.

Service of power units

Maintenance of Audi A4 power units is carried out in the same way for all power units. The service interval is 15,000 km. You can service the engines, both in a car service, and with your own hands.

The maintenance card looks like this:

TO-1: Oil change, oil filter replacement. Carried out after the first 1000-1500 km of run. This stage is also called break-in, since the elements of the motor are lapped.

TO-2: The second maintenance is carried out after 10,000 km of run. So, the engine oil and filter are changed again, as well as the air filter element. At this stage, the pressure on the engine is also measured and the valves are adjusted.

TO-3: At this stage, which is performed after 20,000 km, a standard oil change procedure, fuel filter replacement, and diagnostics of all engine systems are carried out.

TO-4: The fourth maintenance is perhaps the easiest. After 30,000 km, only the oil and the oil filter element change.

TO-5: Fifth TO for the engine, like a second wind. A lot of things are changing this time. So, let's consider which elements will be replaced in the fifth maintenance:

• Change of oil.
• Oil filter replacement.
• Air filter replacement.
• Replacing the fuel filter element.
• The timing belt and roller or chain are changing.
• If necessary, alternator belt.
• Water pump.
• Valve cover gasket.
• Other items that need to be replaced.
• Valve adjustment, in which the gas distribution mechanism is regulated.

Subsequent maintenance is carried out according to the map of 2-5 maintenance for the corresponding mileage.

Conclusion

Audi A4 engines are one of the standards of reliability. At the same time, the design of most motors cannot be called simple. It is realistic to service the power unit with your own hands, but as for troubleshooting, you will need a trip to a car service.
