Audi a3 DIY repair

In detail: do-it-yourself audi a3 repair from a real master for the site my.housecope.com.

The AUDI A3 compact class was introduced to the market in June 1996.

With a length of 4.15 m and a track of 2.51 m, the 3-door A3 provides the necessary comfort. The luggage compartment has a capacity of 350 liters, after reclining the rear seat backrest, the boot capacity increases to 1100 liters.

The car is equipped with a variety of safety equipment. These include the driver and front passenger airbags, as well as the side airbag (from 1997) and the front seat belt pretensioners. Side body reinforcements in the doors further enhance passive safety.

The body is fully galvanized. A ten-year corrosion-free guarantee is provided. To optimize the weight of the car, some of its elements are made of aluminum. These include, for example, door reinforcements or bumper beams.

Driving comfort is enhanced by a subframe to which the front suspension is attached. The subframe is decoupled from the body via rubber mountings and thus dampens vibrations that would otherwise be transmitted to the passenger compartment. Front-wheel drive models use a rear suspension with wishbones and a connecting beam, in which coil springs and shock absorbers are separated from each other for more favorable volume utilization (the previous model used shock absorbers). Thanks to this, it was possible to increase the width of the opening for placing cargo in the trunk.
The all-wheel drive model has double wishbone rear suspension.

The car can be equipped with both gasoline and diesel engines of different power, which allows you to make the appropriate choice depending on the economical or sporty driving character of the owner. This manual describes all powertrains.

The 4-link independent front suspension with installed shock-absorbing struts practically eliminates the influence of the engine operation on the driving process. Front-wheel drive vehicles use a split rear axle arm to optimally position the coil springs and suspension dampers independently of each other. The 4WD model has a double wishbone rear suspension.

The car can be equipped with a five-speed manual gearbox (RKPP), or a four- or five-speed automatic transmission (AT).

The Audi A3 is a compact car with a transverse engine and front-wheel drive or all-wheel drive. The debut of the car took place in 1996. The model is based on the VW Golf 4, but due to the brand image, higher quality workmanship and finishing materials, it had a higher price and occupied the "premium segment" of the golf class.

For the first two years, the Audi A3 was produced only in a three-door body, but already in 1998 a five-door version appeared. The choice of power units is quite wide: buyers were offered a number of gasoline engines, starting with a 1.6-liter model with a capacity of 101 horsepower, two 1.8-liter engines, naturally-aspirated, with a capacity of 125 hp. and a 150-horsepower turbo engine. You could also choose one of two turbodiesel options, 1.9-liter, 90 and 110 horsepower.

In 2000, the model underwent restyling, as a result of which some changes affected the exterior and interior, as well as technical filling: a new turbodiesel with a capacity of 130 horsepower appeared, and the base 1.6-liter engine was also modernized, it became environmentally cleaner and more economical, and its power increased by 1 hp.

The overall reliability of the Audi A3 is high enough, the car is devoid of pronounced weaknesses. The suspension is simple and reliable, the naturally aspirated engines are tough and durable. Turbocharged motors also run for a long time, but they are more demanding on the quality of consumables, and for a long and trouble-free life of an expensive turbine, a number of simple rules must be followed: before starting to move, warm up the engine for a few minutes, and also let the turbine cool down after work - do not turn off the engine after stopping. at least 30-60 seconds. If the previous owner has neglected these rules, the turbine may end prematurely.

In addition to high quality workmanship and reliability, the advantages of the Audi A3 are undoubtedly all-wheel drive, which allows “connoisseurs” to enjoy refined handling in extreme modes and significantly increases dynamics and safety in the cold season.

In the spring of 2003, the 2nd generation of the Audi A3 debuted.

The AUDI A3 compact class was introduced to the market in June 1996.

The car can be equipped with a five-speed manual gearbox (RKPP), or a four- or five-speed automatic transmission (AT).

Recently, manufacturers have been trying to complicate or completely eliminate the possibility of self-repairing a car. As a result, intervention and effective troubleshooting is almost impossible without specialized knowledge and tools.

But if you want to "tinker" with the car yourself and at the same time drive a compact representative of the premium segment, then the old Audi A3 of the first generation is worthy of recommendations. For example, we chose a pre-styling model with a popular 1.8-liter gasoline engine.

Only positive impressions. The car is ideally thought out in terms of ease of self-maintenance. After several operations, you will come to the conclusion that the designers did not seek to complicate the life of inexperienced people, but, on the contrary, tried to help them. For this, everything is done very soundly. Even in spite of the old age (a copy of 1999), the screws are unscrewed everywhere very easily - there is no corrosion.

Many procedures do not require any tool at all. Replacing bulbs in the tail light or front optics, checking fuses, cabin filter, and even ... changing the coolant - you can do all this without using keys!

Armed with a Phillips screwdriver, you can replace the turn signal bulbs. For most of the elements (starter, alternator), access is just a dream.

Difficulties? They cannot be avoided when working with the engine. Only an experienced mechanic can correctly diagnose a malfunction of the timing chain drive and pushers. In addition, some types of operations are quite complex (many elements have to be dismantled) and expensive. So it's better to let the specialists in the services do it.

Circuit breakers.

You will find the entire set of fuses after opening the driver's door on the side of the dashboard. You need to pry off the large cover with a key. A special hole is provided for this in its lower part. On the inside of the cover you will find a pretty clear description of the location of the fuses.

Cooling system.

The manufacturer does not provide for the need to change the fluid (G12 Plus, 5 liters). But you should regularly check its condition, and change the antifreeze every three years. A convenient drain valve is located at the bottom of the radiator.

Cabin filter.

Audi A3 is an example of a reference filter placement. Simply lift up the hood and remove the seal from the engine board. Then lift the plastic cover, detach the two latches and remove the filter. Replacement is provided every 30,000 km. The cost of the filter is from $ 5.

Air filter.

The air filter element is easily accessible. You will find it on the left side of the engine compartment. Using a Phillips screwdriver, remove the two screws and remove the cover from the hooks on the opposite side. The filter element must be replaced every 60,000 km. The cost of the filter is about $ 7.

Headlights and turn signals.

Replacing incandescent bulbs is fairly easy. It is necessary to unfasten and remove the cover under which the incandescent lamps are located.In the case of a turn signal, it is necessary to turn the screw in the holder with a screwdriver through the hole in the wing, and after compression the turn signal will come out.

Rear lights.

Even an inexperienced person will only have a few minutes to replace bulbs in the tail light. Simply remove the lid from the side of the trunk and squeeze the tabs on the lamp plate. You don't even need to disconnect the wiring connector.

Lubrication system.

A 1.8 liter engine requires 4.5 liters of oil with a viscosity of 5W-30 (quality class according to the VW standard 500.00 or 502.00). The filter is located at the front of the engine. It is best to approach it from below. To unscrew the drain plug, you need a 19 mm wrench.

Candles are another example of thoughtful design. They are located deep under the manifold, but the manufacturer has provided a comfortable grip. You will need a long wrench to unscrew the candles. Replacement is recommended every 60,000 km. Candles - NGK BKUR6ET.

Suspension and brakes.

In the front, it is mostly the little things that break. The rear beam is very robust (1). Replacing the stabilizer struts (3), ball arm (4) and brake pads (2) will not seem too difficult to an amateur mechanic.

Working time: 30 minutes - 90 minutes.

Automatic belt tensioner.

The automatic tensioner makes it easy to change the drive belt. But it is located at the front of the engine in a hard-to-reach place. During replacement, it can be difficult to correctly install the belt.

Engine cover.

The 1.8-liter engine is covered with a cover that improves aesthetics and reduces noise levels. To remove it, unscrew the four bolts with a 10 mm wrench.

Timing gear and minor oil leaks.

Replacing the timing belt is recommended every 120,000 km. However, even removing the cover to check the condition of the belt requires a number of preparatory steps. It is better to entrust this task to a mechanic.

The valve cover and crankcase ventilation system are just some of the places where oil leaks can occur. But the top of the engine is covered with a manifold, making it difficult to find leaks.

Self-service on an Audi A3 is pure pleasure. It seems that the designers, creating the car, tried to simplify as much as possible all aspects of daily operation and minor repairs on the road. For example, replacing a light bulb even at night when it rains shouldn't take more than 5 minutes.

Multimedia guide to repair and operation of Audi A3 and Audi S3 cars. The manual covers the Audi A3 and Audi S3 models with 1.6L (AEH), 1.8L (AGN, AGU, AQA, AJQ, APY) in-line four-cylinder petrol engines and 1.9L diesel engines (AGR, ALH, AHF, ASZ), front-wheel drive and with all-wheel drive, production since 1997.

Hundreds of illustrations and photographs show the various stages of repair work on Audi A3 and Audi S3 cars. Quick and easy troubleshooting sections in the repair manual help you troubleshoot. Detailed wiring diagrams help you locate electrical faults and facilitate the installation of additional equipment.

Here you will find data on the repair of: engine, power system, exhaust system, clutch, gearbox, front and rear suspension, steering, brakes, wheels and tires, body, electrical equipment, as well as recommendations for maintenance and diagnostics of electronic systems management. Diagnostic codes are given. In addition to the repair manual, this CD contains detailed operating instructions for the Audi A3.

The Audi car brand is considered prestigious. One of the popular models, the A3, is selling well in Russia. But she has her weaknesses, which, however, are not able to put a stamp on the whole concern or discourage motorists from buying this particular model.

Obviously, used cars imported from European countries and sold in showrooms are subject to the most frequent and expensive repairs.The most common diseases that occur while still under warranty or after a short time after the end of the warranty period for the model are:

Almost obligatory repair of automatic transmission Audi A3
Not very strong and durable suspension
Unpredictable headlight surprises

It's no secret that repairing an Audi A3 is not cheap in an official showroom, even when it comes to minor intervention or standard maintenance. Therefore, there is an alternative to our Autotech Center "Star-Motors", which offers similar services at completely different prices, without reducing the price of quality.

Why Audi A3 is sick

Despite all the external attractiveness and overall reliability of the car, there are still several features that sooner or later all owners of the model encounter:

Acceleration limping due to some properties of the turbine
Weak manual transmission, requiring intervention almost always
Thermal insulation is clearly not designed for the Russian winter cold

Additional difficulties in frosty times:

The machine takes a long time to warm up
Frozen windows do not work
Extraordinary repair of the Audi A3 due to the state of the chassis after winter

Oil consumption must be carefully monitored, otherwise the engine could be damaged. You can track down and eliminate the cause of overconsumption of oil in our car service. Experts are very familiar with the features of the model, so a long diagnostics will not be required, and the repair of the audia3 will be done quickly enough.

If the car is operated in a city, for which it was created, then problems with the brakes almost never arise; from time to time, for preventive purposes, the state of the ABS system should be assessed. To carry out such work, you should contact, if not to a car dealership, then definitely not to the nearest service station, but to where they can competently remove the support, we have the necessary knowledge and equipment for this.

Repair of the Audi A3 engine can be major, or it can be partial. The type of repair is determined only after diagnostics by a minder. Partial overhaul of the Audi A3 engine may include replacing the GBK gasket, replacing valve stem seals, replacing valves. Partial repairs usually do not include removing the engine block, boring, grinding, liner, etc.

You should not decide to repair the Audi A3 engine yourself.People often come to the service who say - “my neighbor told me that I need to change the cylinder head gasket and everything will go away”. Of course, we can listen to the client and go to a meeting, but if this does not help in solving the problem, all responsibility will fall on the client, and not on the service minder who diagnoses and is responsible for him.

The final cost of an engine repair depends on many factors. Often, people disassemble the engine themselves, trying to make engine repairs with their own hands. When it comes to the understanding that they cannot assemble it themselves, they bring us a disassembled engine. When you call the service station, please specify the current condition of the engine and you will be told the exact cost of its repair.

If the car is not in motion, we can send a tow truck.

I noticed that on the Audi A3 2008-2009 they suffer from the problem of the driver's door window regulator, and it is the S-Line.

began with the fact that sometimes the window lifter stopped working, after 3-4 months the car began to open itself, sometimes it did not close, and after that the buttons on the door stopped working altogether
As a result, the car does not close in any way, it is already dark outside, -20 cold.

and then parsing the door in front of the entrance and searching with a tseshka in his teeth, and here is the problem on his head in the form of a broken door harness.

Well, then the collective farm wiring and we are waiting for a new door harness from the ebay

For the first time, the Audi A3 was released in 1996, when it was presented at the Geneva Motor Show. It was from this year that the mass production of the new iron horse began, which joined the golf class. It is also no secret that already at that time the brand was completely owned by Volkswagen, and therefore the Golf, popular all over the world, was used as the basis for the development of the A3. Below I would like to consider the performance characteristics of A3 (8L1) 1996/09 - 2003/05 and A3 (8P1) 2003/05 - 2008.

Let's start with an early model that literally blew up the overseas market. The range of power units with which the A3 is equipped is more than extensive, which has already become a tradition for the German brand in question. Repairs of the 8L1 generation 1996/09 - 2003/05 are often associated with the need to interfere with the operation of the most powerful power unit, which provides the driver with 225hp. The problem is that in the presence of a turbocharger and high power, this engine is not particularly durable, so there are frequent cases of overhaul up to 200-250 thousand kilometers. The most reliable are the naturally aspirated 1.8-liter engine, as well as the least powerful 1.6-liter version with 101hp. Repair of A3 (8L1) 1996/09 - 2003/05, requiring intervention in the operation of these motors, is limited to replacing the timing belt every 60-70 thousand kilometers and timely cleaning of the fuel system. Also, do not forget that German engines are quite demanding on the quality of the consumables being filled, so oil should be purchased only from trusted sellers.

Always in stock and on order (within an hour) all consumables.

Up to 1 year warranty for our work and spare parts.

We will return the repaired car as agreed.

Audi A3 cars are budget cars with reliable engines. Subject to the operating instructions and high-quality consumables, many owners do not experience problems even after 100 thousand kilometers. However, natural wear and tear or the influence of external factors affect the durability of the power unit.It is extremely difficult to carry out repairs with your own hands without knowledge and experience. At our car service, the price of an Audi A3 overhaul starts from 30,000 rubles. We will quickly restore the motor, providing quality assurance.

In addition to natural wear and tear, over time, malfunctions arise as a result of mechanical damage, unreported service calls or the use of low-quality consumable fuel. Symptoms can help determine the presence of problems:

difficulty starting the engine;
the appearance of strong vibrations;
smoke of uncharacteristic colors and volume from the exhaust pipe;
knocking, hum and other noises;
loss of power or dynamics while driving;
increased fuel consumption and other signs.

If the problem is not resolved in a timely manner, the engine will need a major overhaul after 50,000 km.

Despite the great experience of the German company in creating power units, A3 motors have a number of characteristic diseases. Some types of breakdowns are encountered by almost every owner of this car. The main problems include:

breakdown of the thermostat;
deformation of hydraulic supports (cushions);
"Floating" of the unit at idle speed;
increased oil consumption.

With quick troubleshooting and the use of high-quality oil, the engine is able to overcome more than 300 thousand km without breakdowns.

In addition to the whole variety of breakdowns of Audi cars (although we must admit that these are still reliable cars), such as automatic transmission repair, engine repair, steering rack, body and starter repair, there are several more common problems. Here is a kind of TOP of common malfunctions, in addition to those already mentioned:

Typically, the duct comes off at the point of attachment to the engine. Sometimes its debris gets stuck in the fan. However, due to the location of the duct, the power loss should be negligible. To fix this problem, you can simply use tape or epoxy. You can also remove the top of the duct if needed. If the fan is damaged, it may need to be replaced.

Tripping usually occurs when you are idling or when you press the gas pedal. To fix the problem, you need to identify the cylinders due to which the triplet occurs. You can also change the coils or plugs, perhaps they are the reason for the triple action.If so, replace the coils and plugs with new ones. Also, clogged fuel injectors can be another cause of triplet formation. After you have replaced the cylinder, coils and forks, check the operation of the car engine.

This problem occurs when the high pressure fuel system pump does not supply enough fuel. This usually happens when your engine is running at low to medium revs. If the pump is not working, the vehicle is not getting enough fuel. This malfunction can be solved in at least two ways: by replacing the filters or by replacing the entire pump.

Forced crankcase ventilation allows the accumulated gases to be transferred from the crankcase to the intake manifold. When the pressure rises or falls, the gases from the intake manifold return directly to the crankcase. Symptoms of this problem may be oil forced out through the filler cap.
