Everyone knows the reliability of a car brand like Audi, regardless of the model. But no matter how reliable the car is, during operation you have to change certain parts either at the service or on your own. There are many such car owners who repairing Audi A4 with their own hands... Someone may just like to do something on their own, but for someone the services of the service seem too expensive. Basically, attention has to be paid to the car's suspension, the fuel system, and other little things. Some even after an accident restore cars on their own.

The main thing to remember when repairing an Audi A4 with your own hands is that all actions are performed correctly, and then you do not have to contact the service and pay money. Below we will consider some of the car malfunctions, in particular, the repair of the ABS unit and the headlight auto-corrector sensor.

The ABS unit may not work for various reasons. It can fail completely and it will need to be replaced, someone buys a car with a no longer working unit and has to be repaired. For those who have no experience in working with trace elements, it is better not to go into the block, because you can make it even worse. If the ABS indication on the panel is off, we start looking for the problem. You need to short-circuit two wires - yellow / red and brown and unsolder them. After that, the light starts to burn. But even after that, it’s impossible to come in like a lump. The unit itself needs to be repaired.

To do this, remove the front left wheel and wheel arch liner. Next, the washer reservoir and hydraulic fluid are removed. Two connectors are removed - from the block itself and from below. It is necessary with the help of T-20 to unscrew 6 bolts and remove the ABS block. As a result, we have the electronic part of the unit in our hands. Next, you need to open it with a construction knife. Inside, you need to find two thin silver wires. Usually there is poor or no contact in this place. Possible oxidation must be removed from the contact points of these wires. To restore contact, a thin copper wire is taken and soldered to the pad from the connector side. Silver wires are tinned.

Next, you need to move the copper wire to the silver one and solder them together. The remainder is bite off in pieces.Then the block must be sealed back, you can use hot melt glue. After that, it is installed in the reverse order and checked by a vag-lump. If it is clear with the ABS unit, then sometimes the headlight auto-corrector sensors on the Audi A4 can cause trouble. In most cases, these sensors fail due to condensation.

Although Hella is one of the best, if not the best manufacturer of optics, it still doesn't take very good care of moisture protection. This means that the board is not varnished. Although all the joints are dense, moisture, nevertheless, is formed there. There is only a small hole in the housing to equalize the pressure as the temperature changes. Perhaps moisture gradually penetrates through this hole. As a result, after opening the case, moisture is observed inside.

How the body of the Audi A4 is repaired, you will know by watching the following video.

How does the rear of a car deform in a collision at low speeds? Damage to the rear bumper is always observed, the trunk moves up, the wing may "shoot", as evidenced by the dent on the rear arch. With a strong impact, the spar can be crushed.

It is very difficult and time-consuming to repair the body, but when you have enough time and the right tool at your disposal, you can safely get down to business:

• remove lighting devices and all electrical wiring from the place to be repaired
• after pulling the spar itself. This is where you need a winch. Fasten the grips exclusively in the areas of horizontal seams (factory welding). Pinpoint the correct direction and pull out the damaged link.
• use the same method to stretch the wing
• trim the floor in the boot if it is also damaged

When a strong blow has hit the rear of the car, a complete replacement of body panels and power elements may be necessary. When folds appear on the side member, it must be replaced, since it will no longer be able to give the body the nominal stiffness.

You can pull the spar with chains or a jerk of the cable, but these options are unacceptable for the Audi A4. The spar of a modern car is a kind of cassette that absorbs the impact energy in a collision, so it should not be used after a serious accident.

When repairing a body of high complexity, it is better to resort to the help of specialists, since they will have the necessary knowledge and devices in service. If you nevertheless decide to repair minor damage yourself, then in order to minimize errors, watch the video tutorial on repairing the body of the Audi A4.

Attention: Replace spark plugs only when the engine is cold or thawed to the touch. If the spark plugs are removed while the engine is hot, the thread for the spark plug in the light alloy cylinder head may be stripped.

Audi A4 (8D2, B5) 1995 - 2000

A car is an irreplaceable thing, especially when you consider that it gives you more freedom of movement and allows you to forget about stuffy public transport. This is what becomes the reason that people buy their own vehicles, opting for the Audi 4.

However, every machine needs proper care. Every repair, no matter how serious the damage, can be done by hand. Minor breakdowns can be eliminated on your own, for this you do not need to go to a service center, spend a lot of money and nerves. On our website you can find repair manual Audi A4... which can be applied by replacing the shock absorbers or replacing the thermostat. having even minimal skills in putting cars in order.

Audi A4 has its own internal designation, according to which it belongs to type B. This car is the successor of the series called Audi F103, which included Audi models with an indication of the number of horsepower (60,75,80, super 90). After rebranding in 1994, the Audi A4 name is used for every model in this series.

The Audi A4 car is produced in huge quantities, but even this is not enough to meet the needs of all of Europe. In 2007, this model was one of the leaders in the number of new vehicles registered in Germany. Audi A4 could not get around only BMW and two models from Volkswagen.

At the moment, the Audi A4 continues to be successfully produced in Germany. Since 2007, the manufacturing plant has been producing the only model belonging to this class - A4 B8. This vehicle is reliable, has increased durability and can, with proper care, serve for more than a dozen years.

Repair and operation of Audi A4 quite simple, the main thing is to have an idea of ​​the details of the car. You can also make sure of the ease of operation by looking at how the cabin filter is replaced and the air filter is replaced. If you doubt your knowledge a little, you can use the information on our website. It is here that we have published a book on repairing an Audi A4, which even a person who has never worked with cars can master.

All car owners of Audi cars and in particular the Audi A4 Good day. Today I will try to tell you as clearly as possible about the operation and repair of the Audi A4 car. Everyone knows the high quality of German cars, but still, regardless of the brand, from time to time you have to think about buying certain parts, replacing consumables, etc.So that your car does not cause trouble, keep an eye on it, take the necessary maintenance measures on time and your “iron horse” will continue to delight you for a long time.

In order not to beat around the bush, I'll get straight to the point. Those who are in the subject know that the Audi ay4 has been refined, changed, improved from generation to generation. All new systems appeared in the equipment that endowed the car with safety, ease of control, etc. To date, many electronic systems have been implemented in the Audi A4 and it is really comfortable and convenient to operate this car, although I have no doubt that there will be those who will have something to complain about. So, about the exploitation.

Power unit... The engine, without exaggeration, is the heart of any car and if it works intermittently, then there is no need to talk about any comfortable handling. In gasoline engines of the Audi A4, oil must be changed every 15 thousand km. The procedure is carried out together with the replacement of the oil filter. In diesel engines, the oil must be changed every 7 thousand km. So that there are no troubles and any questions in the future engine oil should be used only that recommended by the manufacturer. It is clear that not everyone adheres to this. However, this should not be forgotten.

In addition to oil, it is important to remember about the timing belt, which must be replaced every 60 thousand km. Yes, Audi recommends changing the belt after 120 thousand km, however, there are cases when it broke off at 70 thousand km. I think that changing the belt will still be cheaper than repairing the engine later if it breaks. An important point if you have become or want to become the owner of such a car as Audi, and not only Audi, is the availability of quality service. Now there are a huge number of services, but finding a decent one is a problem. Why am I talking about services? The fact is that you can meet many owners of the Audi A4, who, during the operation of this car, are simply unhappy with them because of the problems that arise. So before buy a used car find normal service and diagnose the machine. And pay more attention to cars with diesel engines. In the event of problems, the repair of such a unit will not be cheap, and besides this, again, there will be a problem with finding a quality service.

Gear boxes... On the topic of repair and maintenance of the Audi A4, of course, it is worth mentioning the checkpoint. If we recall the first generation of the Audi A4, then these cars were equipped with an automatic machine, mechanics and tiptronic. Already in the next generations, a multitronic variator was offered. As you know, initially, he did not particularly please the owners with his reliability, but gradually the design was being finalized and becoming more reliable. As for the automatic and manual transmissions, in principle, they do not cause any special problems. What you should pay attention to is changing the oil every 50-60 thousand km. and those who have come across this procedure know that the cost of oil is quite high. In addition, on machines equipped with mechanics, it is likely that the clutch will need to be replaced when the mileage is over 120 thousand km.

Quattro all-wheel drive... In principle, there is nothing negative to say about the all-wheel drive system. It is quite reliable, but, nevertheless, after 200 thousand runs, you may have to think about repairs.

Suspension... Since we are talking about the operation of the Audi A4 in Russian conditions, then with a mileage of about 30 thousand km. you can observe the backlash of the hinges of the lower arms. The upper levers take longer to take care of and you have to think about replacing them at 50-60 thousand km. mileage. The weak elements of the suspension include the old-style anti-roll bar struts. They should be changed every 15-20 thousand km. Old-style racks are meant before 1997. After that, this suspension element has become much more reliable. For shock absorbers - they have to be changed every three to four years. You can assess their condition by visiting the service. In general, the suspension of the Audi A4 should be devoted to a separate article, which I will try to do in the near future.

With regard to the suspension, I would like to note that on all-wheel drive audi a4 the design is somewhat more complicated than on a front-wheel drive car. However, this does not diminish the number of fans of the Audi A4 quattro. All the same, all-wheel drive has significant advantages. But telling that one thing is important to try. Perhaps this is the main thing that I wanted to describe about the operation and repair of the Audi A4 car. I hope you find this article useful and you will at least generally know when and where to look for timely service. Good luck on the road!

It is necessary to get rid of such motors, not to reverse it

She will not start in the cold with such a butter dish. There is no compression in the cylinders.

It is clear that pensioners have nothing special to do, but there is not much sense in inventing something that has long been invented. The so-called oil washer is sold and costs ue. And the fact that it flies from the sopun like that, maybe it's time to change the rings with caps, and not suffer from nonsense. At the expense of the nozzles, this is generally nonsense, but for the sake of experiment I wonder how much it sounds like

Repair steering rack do it yourself

The control rail is the main element of the control control and, according to the deflot, must always be exclusively in good technical condition.

Control rail design

In fact, on all car models, the design of the control rack is the same type and therefore we will discern its general structure.

The steering rack consists of:

Bushing housings;
Shaft with teeth and threads at both ends for connecting control rods;
A control gearbox consisting of a shaft with worm teeth, a stubborn bearing and a shaft bearing, a gear cover that presses the shaft cracker, a spring and a cap that serves to adjust the pressure of the cracker to the rack shaft;
Control rods with control tips (left / right);
Anthers of the rails with fastening clamps;

The shaft of the rack is sealed against the occurrence of free play by the bushing, and somewhat on the other side by the pressing crack of the control gear.

Control rail malfunctions

Malfunctions reiki expressed in the occurrence of knocks, tight rotation of the steering wheel, in other words, the steering wheel jamming during rotation. In the bulk, the occurrence of these defects is caused by a violation of the integrity of the protective anthers of the control rail.
Through the warped boot, moisture and dirt get into the “bulb” of the control rods, into the sealing sleeve of the shaft, onto the rack shaft itself, onto the parts of the control gear, which reduces their service life several times.

Therefore, it is recommended to undergo repeated diagnostics of the suspension and the manager of the accounting system to detect defects at their early stage. This will prevent the wear of suspension parts and the manager of the accounting software complex and save your own money on expensive repairs.

The operation on the repair of the control rail is not particularly difficult and the repair is carried out by their forces you will like it done by any car enthusiast.
Because the device of most of the rails is of the same type, here we will not dwell separately on the repair of the control rail of a VAZ, Audi or Mitsubishi, but we will consider the general points of repair.
