Volkswagen Touareg Wiring Diagrams. Fuse and Relay

Volkswagen Touareg I

Volkswagen's first SUV, which debuted in 2002, quickly gained popularity: it was more comfortable, more "passenger" than direct competitors. At the same time, there were no problems with off-road patency either. In addition, the Touareg was well equipped and cost less than premium models. The weakest point of the first generation SUV was reliability. Here are the problems that a used Touareg can present to its owner.

 

1. Timing chains

The problem with quickly stretching chains affected the Touareg less than other Volkswagen models, because it was not equipped with gasoline “fours” - only VR6 and V8 engines. But when the chains do wear out, replacing them becomes a problem!

 

What to do

Keep your chains young. They can stretch up to 150 thousand km (for the VR6 of the first years of production, this happened before), if it is too rare to change the oil in the engine or fill it with insufficient quality. And they can serve even 250 thousand km - but by this moment it is still worth saving the necessary amount for repairs. Otherwise, gasoline engines go to overhaul, which may be required somewhere around 350 thousand km.

 

2. Climate system

In general, the air conditioning system is reliable, and problems arise due to the fact that the first generation cars are already quite old and with high mileage. After 150 thousand km, the air conditioner radiator and compressor fail - especially on cars with V8 engines. By 200 thousand km, the heater fan and dampers may break, and if the car has four-zone climate control, the air conditioner for the rear passengers will also require repairs.

 

What to do

Most air conditioning malfunctions are caused by dirt and chemicals that corrode aluminum pipes and radiators. Therefore, prevention of the air conditioner does not hurt - it needs to be serviced periodically, and the radiators should be washed.

 

3. Air suspension

Most of the first generation cars are equipped with air suspension, and it is a headache for owners. After 2-3 years of operation, problems can begin at any mileage.

 

What to do

Fortunately, the main components of the "pneuma", cylinders and compressor, are quite reliable. For example, a pump serves 150–200 thousand km. More often fail valves on the racks and sensors - clearance and temperature of the compressor. To avoid costly repairs to the pneumatic system, it is recommended that it be diagnosed at least once every two years, and if a sensor or valve fails, do not hesitate to replace it.
