Audi a3 DIY repair

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

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 trunk has a capacity of 350 liters, after reclining the back of the rear seat, the capacity of the trunk increases to 1100 liters.

The vehicle is equipped with a variety of safety features. These include airbags for the driver and front passenger, as well as a side airbag (since 1997) and front seat belt tensioners. The side reinforcements of the body in the doors further increase passive safety.

The body is completely 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, reinforcements in doors or beams in bumpers.

The subframe to which the front suspension is attached contributes to an increase in driving comfort. The subframe is decoupled from the body via rubber mounts and thereby dampens vibrations that would otherwise be transmitted to the passenger compartment. Front-wheel-drive models use a linkage-link rear suspension with separate coil springs and shock absorbers for better use of volume (previous model had suspension struts). 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 a double wishbone rear suspension.

The car can be equipped with both gasoline and diesel engines of various capacities, which allows you to make the appropriate choice depending on the owner's economical or sporty driving style. This manual describes all power units.

4-link independent front suspension with installed shock absorbers virtually eliminates the influence of the engine on the driving process. For front-wheel drive vehicles, a compound rear axle arm is used, which allows optimal placement of coil springs and suspension dampers independently of each other. The all-wheel drive 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).

Audi A3 is a compact car with a transverse engine and front- or all-wheel drive. The debut of the car took place in 1996. The model was built on the basis of the VW Golf 4, however, due to the brand's 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 powertrains is quite wide: customers were offered a range of gasoline engines, starting with a 1.6-liter model with a capacity of 101 horsepower, two 1.8-liter engines, atmospheric, with a capacity of 125 hp. and a 150-horsepower turbo engine. It was also possible to choose one of two turbodiesel options, with a volume of 1.9 liters, with a capacity of 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 stuffing: a new turbodiesel with a capacity of 130 horsepower appeared, and the base 1.6-liter engine was also upgraded, it became environmentally cleaner and more economical, and its power increased by 1 hp

The overall reliability of the Audi A3 is quite high, the car is devoid of pronounced weaknesses. Suspension is simple and reliable, naturally aspirated engines are hardy and durable. Turbocharged engines 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: warm up the engine for several minutes before starting to move, and also allow the turbine to cool after work - do not turn off the engine after stopping for at least 30-60 seconds. If the previous owner neglected these rules, premature "death" of the turbine is possible.

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

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

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 are trying to make it difficult or completely eliminate the possibility of self-repairing a car. As a result, intervention and effective troubleshooting are almost impossible without special 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.

Impressions are only positive. The car is thought out perfectly in matters of ease of self-maintenance. After several operations, you will come to the conclusion that the designers did not seek to complicate the lives of inexperienced people, but rather tried to help them. For this, everything is done very soundly. Even despite the advanced age (1999 copy), the screws are unscrewed everywhere very easily - there is no corrosion.

Many procedures do not require any instrument at all. Replacing bulbs in the rear light or headlights, 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 bulbs in the direction indicators. For most elements (starter, generator) 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 specialists in 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. It is necessary to pry off the big cover with a key. In its lower part, a special hole is provided for this. On the inside of the cover you will find a fairly clear description of the location of the fuses.

Cooling system.

The manufacturer does not provide for the need to replace the fluid (G12 Plus, 5 liters). But you must regularly monitor its condition, and change the antifreeze every three years. At the bottom of the radiator is a convenient drain valve.

Cabin filter.

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

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, unscrew the two screws and pry the cover from the hooks on the opposite side. The filter element must be changed 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 there are incandescent lamps.In the case of a turn signal, it is necessary to turn the screw in the holder through the hole in the wing with a screwdriver, and after compression, the turn signal will come out.

Rear lights.

Replacing the bulbs in the rear light, even for an inexperienced person, will take only a few minutes. Simply remove the trunk lid and squeeze the tabs on the lamp plate. You don't even have to unplug the wiring connector.

Lubrication system.

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

Another example of thoughtful design is candles. They are located deep under the collector, 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.

The front breaks mostly little things. The rear beam is very strong (1). Replacing the stabilizer links (3), ball lever (4) and brake pads (2) will not seem too difficult for 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 in front of the engine in a hard to reach place. During replacement, it may be difficult to properly 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 drive and minor oil leaks.

Timing belt replacement is recommended every 120,000 km. However, even removing the cover to monitor the condition of the belt requires a number of preparatory steps. This task is best left to a mechanic.

The valve cover and crankcase ventilation system are just some of the places where oil leaks can occur. But the upper part of the engine is covered by a manifold, which complicates the search for leaks.

Self-service Audi A3 - pure pleasure. It seems that the designers, creating the car, tried to simplify as much as possible all aspects of everyday operation and minor repairs on the road. For example, changing a light bulb, even at night when it is raining, will not take more than 5 minutes.

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

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

Diagnostic codes are given. In addition to the repair manual, this disk contains detailed operating instructions for the Audi A3.

The Audi car brand is considered prestigious. One of the popular models - A3 sells well in Russia. But she has her weaknesses, which, however, are not able to put a stigma on the entire 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 a short time after the end of the warranty period for a model are:

Practically obligatory repair of automatic transmission Audi A3
Not very strong and durable suspension
Unpredictable surprises from the headlights

It's no secret that in an official salon, repairing an Audi A3 is not cheap, even if it's a minor intervention or standard maintenance. Therefore, alternatively, there is our Star-Motors Autotechnical Center, which offers similar services at completely different prices, without reducing the quality.

What are sick Audi A3

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

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

Additional difficulties in frosty times:

Machine takes a long time to warm up
Frozen power windows not working
Extraordinary repair of the Audi A3 due to the state of the chassis after the winter

It is necessary to carefully monitor the oil consumption, otherwise you can ruin the engine. You can track and eliminate the cause of excessive oil consumption in our car service. Specialists are very familiar with the features of the model, so long diagnostics are not required, and the repair of audia3 will be done quickly enough.

If the car is operated in the city, for which it was created, then there are almost never problems with the brakes, from time to time, for the purpose of prevention, the condition of the ABS system should be assessed. To carry out such work, you should apply, if not to a car dealership, then definitely not to the nearest service station, but to where they can competently remove the caliper, 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 the diagnosis by the minder. Partial repair of the Audi A3 engine may include replacing the cylinder head gasket, replacing valve stem seals, and replacing valves. Partial repairs usually do not include removal of the engine block, boring, grinding, sleeve, etc.

You should not make a decision to repair the Audi A3 engine on your own.People often come to the service who say - “a neighbor told me that I need to change the cylinder head gasket and everything will pass.” Of course, we can listen to the client and meet him, but if this does not help in solving the problem, all responsibility will fall on the client, and not on the service minder who makes the diagnosis and is responsible for it.

If the car is not running, 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 namely the S-Line.

it started with the fact that sometimes the power window stopped working, after 3-4 months the car began to open itself, sometimes 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's the problem on his head in the form of a broken door harness.

well, then the collective farm wiring and waiting for a new door harness from ebay

For the first time, the Audi A3 saw the light in 1996, when it was presented at the Geneva Motor Show. It was from this year that the mass production of a new iron horse began, which joined the golf class. It is also no secret that already at that time the brand was wholly 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 foreign market. The range of power units that the A3 is equipped with is more than extensive, which has already become a tradition for the German brand in question. Repair of the 8L1 generation 1996/09 - 2003/05 is often associated with the need to intervene in the operation of the most powerful power unit, which provides the driver with 225hp. The problem is that in the presence of turbocharging and high power, this engine is not particularly durable, so there are frequent cases of major repairs to 200-250 thousand kilometers. The most reliable are considered to be a naturally aspirated engine with a volume of 1.8 liters, as well as the least powerful 1.6-liter version with 101 hp. Repair A3 (8L1) 1996/09 - 2003/05, requiring intervention in the operation of these engines, 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 consumables being poured, so oil should be purchased only from trusted sellers.

Always available and under the order (within an hour) all consumables.

1 year warranty on our work and 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 or the influence of external factors affect the durability of the power unit.Do-it-yourself repairs without knowledge and experience are extremely difficult. At our car service, the price of an Audi A3 overhaul starts at 30,000 rubles. We will quickly restore the motor, providing quality assurance.

In addition to natural wear and tear over time, malfunctions occur as a result of mechanical damage, outdated service calls or the use of low-quality consumable fuel. The following symptoms help identify 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 when driving;
increase in fuel consumption and other signs.

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

We repair both petrol and diesel engines!

Despite the great experience of the German company in the creation of power units, engines on the A3 have a number of characteristic diseases. Almost every owner of this car encounters some types of breakdowns. The main problems include:

thermostat failure;
deformation of hydraulic supports (pillows);
"swimming" of the unit at idle;
increased oil consumption.

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

In addition to all the variety of breakdowns of Audi cars (although it is worth recognizing 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:

Usually the air duct comes off at the point of attachment to the engine. Sometimes its fragments get stuck in the fan. However, due to the location of the duct, power losses should be negligible. To solve this problem, you can simply use tape or epoxy. You can also remove the top of the duct if necessary. If the fan is damaged, it may need to be replaced.

Usually tripping occurs when you are idling or when you press the gas pedal. To fix the problem, you need to determine the cylinders due to which the tripling occurs. You can also change the coils or plugs, perhaps they are the cause of tripling. If so, replace the coils and plugs with new ones.Also, another cause of tripling can be clogged fuel injectors. After you have replaced the cylinder, coils and plugs, check the operation of the car's engine.

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

Forced crankcase ventilation allows the transfer of accumulated gases 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.
