Passat b6 DIY repair

Details: Passat B6 DIY repair from a real master for the site my.housecope.com.

The sixth generation Passat appeared on the market in August 2005. The conveyor of the German concern worked on the production of the car until 2010. The car was presented with sedan and station wagon bodies. At the same time, he distinguished himself by his own name - Variant. The iron horse was produced in Germany, which speaks of a first-class assembly. It was on this car that the engineers of the German brand relied on after the release of the not completely successful Volkswagen Passat B5.

In many ways, motorists only note the advantages of the model. The list of advantages includes:

  • rich functionality;
  • quiet, smooth running;
  • high corrosion resistance of the body (double-sided galvanized);
  • transformable salon.

The owner will be pleased with the volumetric trunk with an anti-friction floor. But, like any mechanism, the Passat has certain flaws. Among the disadvantages of Volkswagen, there is insufficient visibility. This is due to the fact that the right rear-view mirror is smaller in size than the left one. There is also a low level of reliability of certain units and mechanisms. All this leads to breakdowns of varying complexity and the need to carry out repairs.

All cars in the line are equipped with 1.9 TDI and 2.0 TDI engines. The turbo diesel engine is highly reliable and economical. The most promising and successful is the 1.9 TDI bzb engine with 105 horsepower.

Scheduled technical inspections of the B6 line engines are provided every 15 thousand km. But you should understand that this is not the cheapest deal. However, maintenance must be carried out regularly. The engine is located longitudinally under the hood. This often complicates inspection and makes it more problematic. Maintenance and repair of the B6 diesel engine is rightfully considered a painstaking task. So, to replace the timing belt, it is necessary to disassemble almost the entire "apron". And this is far from easy and relatively inexpensive.

The quality of the fuel used also affects the wear of the parts. The Volkswagen Passat engine, or rather its injectors will be short-lived, will lose tightness in the area of ​​the cylinder head. This flaw is observed in the bzb models released in 2007.

In the same time 2.0 is considered the most problematic variation TDI for 105 horses... This is the weak point of the entire automotive range of the German concern. The service life of the unit injectors barely reaches 90 thousand km. And the malfunctions that will lead to the repair of the bzb engine will begin with a knock, a failure in optimal functioning in winter. It is noted that breakdowns most often begin due to the failure of the air flow sensor. It is this structural element that does not have a high quality workmanship.

This system is characterized by the least problems. But experts recommend from time to time to diagnose such bzb engines. This is best done every 30,000 km. As a rule, the loss of power on them is associated with the appearance of carbon deposits on the injector. It occurs only on those engines whose owners like to drive with full gas.

Previously on the Passat B6 (until 2006), the particulate filters were out of order... Our drivers solve this issue in 2 stages:

  • removal of a structural element;
  • reprogramming of the control system according to the specified parameters.

It is worth noting that the majority of car owners who ask to remove soot and replace the filter are Volkswagen drivers, in particular the Passat B6.

It must be emphasized that when driving this vehicle, only first-class oil should be used. It is best if it is an original product with factory approvals. If you do not adhere to the recommendation, then the failure of the oil pump will be inevitable.Another not entirely pleasant question is the replacement of the front hydraulic mounts of the bzb engine. They need repairs every 60 thousand km.

As a rule, Volkswagen candles change quickly enough. At the same time, the replacement does not require the use of professional tools. To install new plugs, first of all you need to unscrew all the screws, and then remove the bzb motor protection cover.

After completing the above operations, you need to apply markers to high-voltage wires, remove their tips from the spark plugs. Next, the candles are cleaned. In order to make the process as convenient and correct as possible, brushes of different sizes and a hand-held vacuum cleaner are used. The spark plug wrench is used to unscrew the spark plugs. This is done just before cleaning the elements of the bzb engine.

The next step is the replacement of the candles itself. This process is carried out in the reverse order to that indicated above. It should be noted that in order to avoid troubles and incorrect operation of the motor, the installation of candles should be carried out exclusively for the Volkswagen Passat B6... This requirement is due to the fact that for the correct operation of the engine and the machine as a whole, the correct functioning of the spark plugs is necessary.

The air filter on the Passat lends itself to self-replacement. Repair does not take much time and is simple. The only requirement is the availability of tools and relevant knowledge.

Replacement is carried out in several stages:

  1. You need to open the hood of the car and secure it.
  2. The next step is to remove the bolts from the box that holds our part. This is done using a conventional Phillips screwdriver.
  3. It is worth paying attention to the fact that it is necessary to start dismantling the filter only after disconnecting from the box the contact pipe through which the air is supplied.
  4. Immediately after unscrewing the bolts, you need to slightly lift the cover, which will allow you to get the filter. You need to do this very delicately, so as not to scatter the debris stuck in the parts that have accumulated in it. In this case, there is no need to loosen the part from side to side: the filter can be removed easily, it is enough just to grab it correctly.

Installing a new component in the bzb motor is simple: just do the above operations in reverse order.

It is not so difficult to clean the injector with your own hands. Difficulties lie only in the duration of the work and the complexity of the process. To do cleaning, you need to arm yourself with a washing liquid. The cleaning agent bottle must be connected to the injector of the machine.

After flushing, start the bzb engine. Manual cleaning often takes about an hour of free time from the Volkswagen owner.

The workshop uses a different flushing system. The most optimal is liquid flushing with dismantling of elements. The necessary equipment is always available in the workshop. So, professionals use a special stand that can work simultaneously with several fuel injectors. And this is important from the point of view of saving time. Its advantages are as follows:

  • the ability to measure and compare the quantitative and qualitative fuel consumption;
  • visual comparison and control of the spraying of diesel, gasoline by one nozzle in different modes, which accurately simulate the operation of the engine;
  • the ability to check the tightness of the structural components of the fuel spray system.

The whole procedure is reduced to the "test-cleaning-test" chain. In this case, deviations in the fuel supply before and after cleaning should not exceed 1.5%.

It is worth noting certain structural elements of the machine that may fail:Image - Passat b6 DIY repair

  1. Suspension... In general, this is a reliable part with the exception of the wishbone silent blocks. Factory hinges are not designed for our roads either. They are not particularly durable.
  2. Chassis... Discs and pads may also need to be repaired soon. The critical moment in their work is squeals, squeaks when the speed is reduced.Suspension problems include issues with the angles of the rear wheels. They react very painfully to attempts to overcome such an obstacle as a curb. Therefore, fans of parking on the lawn will soon be repaired or frequent visits to the service center to carry out the “wheel alignment” procedure.
  3. Electrical equipment Volkswagen isn't perfect either. But there are not so many faults here. Most often, problems relate to all kinds of sensors, which leads to engine failures in starting. Also, turn signal relays with emergency lighting will not last long.
  4. Lower door moldings B6 models after 2007 release are rather fragile. They need respect. If you carry out door repairs, you will have to cut off the factory moldings, and install new ones in their place.

In general, the Volkswagen Passat, which has a bzb engine, is considered a fairly good car even on domestic roads. Nevertheless, the frugality of personal transport has always been welcomed. Love and constant care of the car will allow you not to spend money on long-term repairs.

Volkswagen produces reliable, inexpensive cars with German quality and comfort. More and more people around the world are choosing this brand. Since 1999, Volkswagen sales have increased by 20% annually. Since 2009, Volkswagen has been one of the largest car manufacturing companies in the world. The concern consists of more than three hundred companies. Audi, Bentley, Porsche, Skoda, Seat, Bugatti, Lamborghini, Scania - all these are parts of the Volkswagen concern. Cheap Volkswagen car options are popular. In Russia, they are usually brought to technological perfection and do not have "childhood" diseases.

For their cars, Volkswagen uses the usually popular and reliable automatic transmissions. Most of them are able to honestly leave the entire reasonable service life of the car, if, of course, they are serviced on time and are not exposed to unnecessary stress. Volkswagen automatic transmission repair is rarely required, is well studied and does not pose serious problems for service station specialists.

Volkswagen Passat B4 car

For the Passat B4 and Golf model with automatic transmission 096, the following repair features are characteristic:

  1. It is better to order original gaskets and oil seals for Passat B4 and Golf, the rest are of poor quality, except for budget products from Atok.
  2. Rubber pads on pistons lose their properties over time and begin to hold pressure poorly. The entire set of pistons must be replaced or the vehicle has been in service for more than ten years.
  3. As a result of exposure of the hydraulic plate to contaminated oil, the pressure regulator, the torque converter lock-up solenoid, the pressure control valve, and the solenoid valve may fail. After 150,000 runs on the Passat B4, it is necessary to clean the automatic transmission valve body from dirty oil.
  4. After ten years of operation of the Passat B4 and Golf, the properties of the wiring change, the resistance increases and the computer may start giving errors. Therefore, together with the solenoids and sensors, during overhaul, their wiring also changes.
  5. From old age or excessive load, the return springs may fail, which will lead to the inability to engage reverse gear. After ten years, their condition should definitely be checked.

For the Passat B5 models with automatic transmission 01M, the following repair features are characteristic:

DO NOT SPEND MONEY ON REPAINING!
Now you yourself can remove any scratch from the body of your car in just 5 seconds.

    1. It is better to take only original compression rings for Passat B5. The only analogue is only from the Atok company.
    2. Rubber on the Passat B5 is made of poor quality, in the cold it quickly loses its properties, dries out over time. After a few years, oil begins to leak. At the first sign, you need to change the pistons. This usually applies to machines that have been in operation for more than 10 years.
    3. The sliding bearing on the Passat B5, mounted on the front drum, is made of plastic.Over time, it loses its characteristics and at one point it simply scatters, damaging the machine gun with its remains. You can check its integrity by examining the pallet, if it is strewn with plastic fragments - it's time to change the bearing.

    1. The solenoids are quite reliable. Over time, the pressure regulator and ball-type solenoids may fail. Their normal lifespan is about ten years.
    2. After 200,000, or better before, it is necessary to flush and clean the valve body from dirt. Dirty oil has the ability to abrasively process the insides of the valve body and "eat up" the metal of the valves and spools. The wear of the plate with dirty oil can be so severe that it must be replaced as an assembly.

    For the Passat B6 model with automatic transmission 09G, the following repair features are characteristic:

      The Passat B6 automatic transmission is not demanding on completely clean oil, filters are used with an outdated design, however, they serve up to 200,000, after several oil changes and washes. However, when repairing after overheating of the box, it is better to replace the filter with a new one. When overheated, it will take away the remnants of the clutches and their glue, which will be impossible to get out of the filter. When installing such a filter back, the remnants of the clutches will fall into the box.

    For the Passat B6 and Sharan models with automatic transmission 5HP19 EYF, the following repair features are characteristic:

    1. The 5HP19 EYF automatic transmission on Sharan lives well over 200,000 kilometers. This box forgives both slippage and overheating, but does not like dirty oil or its low level. Oil starvation is capable of destroying everything in the boxes. From valve body to clutches.
    2. For the 5HP19 EYF service staff, Sharan is known primarily for its torque converters. Their forced blocking eats up the friction linings, which leads to severe oil contamination and subsequent repairs.

    Repair and diagnostic procedures for automatic transmissions require special equipment and knowledge. However, Volkswagen transmissions are well studied and if you have the means and desire, you can try to repair them yourself. But, most likely, it will be cheaper to give this business to professionals. Repair of a Volkswagen Tuareg automatic transmission in Rostov, for example, will cost from 12,000 rubles in a normal service. Trained and experienced service employees will handle the repairs much faster and better.

  • Before opening the Passat b6, it is recommended to untangle and straighten the hook, this is necessary for more accurate work. For work, you only need the end of the hook, it should be 50-60 cm long.
  • The longer end of the hook is used as a lever. It must be inserted with a wedge into the outer rubber sheathing and then slide down.
  • After that, you need to find a locking mechanism. In the vast majority of models, it is located in the doors, at a distance of about 20 cm from the place where we stuck the hook. This pin looks like a cylinder, which allows you to open and close the car when moving horizontally.
  • Finally, you can proceed to the direct "opening" of the machine. The found closing mechanism is required to act with a pin until the door is unlocked. The procedure will take no more than 5-7 minutes.

There are other fairly simple ways in which the car will be reopened. They will work in cases when the keys are in your hands, but for one reason or another "refuse" to work:

  1. You can "wake up" the alarm system in the following way. Try to open the luggage compartment with the key. If you succeed, then check if you have sockets there - the fact is that it is not present in all trim levels. If there is, then try to supply electricity to it. The machine can then start working again.
  2. Option for summer use. Before you open the Volkswagen Passat B6 without a key, you will need to remove the front left wheel arch liner. There should be a hood release cable. We pull it - and we get access to the battery. Now you have the opportunity to recharge it.
  3. Finally, the classic way is to break the window. This procedure can be performed with any window, except for small side windows, because they are considered the most expensive to restore.
