In detail: do-it-yourself Volkswagen Passat B6 repair literature from a real master for the site my.housecope.com.
Content
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:
- You need to open the hood of the car and secure it.
- The next step is to remove the bolts from the box that holds our part. This is done using a conventional Phillips screwdriver.
- 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.
- 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:
- 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.
- 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.
- 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.
- 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.

if only there was more or less localization.
If something like that already exists, please do not kick too much, but just quietly demolish this topic.
If not, then I propose to publish here various materials on the Passat B6, such as: descriptions of the systems and components of the car, training programs and other similar information.
The general idea of the topic: to collect and organize such materials in one place.
