Do-it-yourself Tuareg pneumatic compressor repair

In detail: do-it-yourself Tuareg pneumatic compressor repair from a real master for the site my.housecope.com.

Perhaps, many motorists, and just those who are simply interested, know all the advantages of the air suspension of the Volkswagen Tuareg car. But, in addition to these pluses, there are also minuses, this is natural. The disadvantages, of course, include the problem of leaking air bellows. Unfortunately, this sometimes happens, albeit on high runs. Fortunately, the factory supplies special repair kits with which this problem is solved.

Usually, the problem starts to manifest itself gradually. After a long parking (several days) - You may find that the car has dropped on one wheel. Or on one axis, thus forming an unnatural roll. After you start the engine, the level of the body will be leveled and everything will work normally until you leave the car again for a long time. If the situation repeats, then there is an air leak from the system. The tightness is lost. We strongly recommend not to delay contacting the service as soon as you notice similar symptoms. This is due to the fact that in the absence of tightness, oxidative processes inside the air spring can intensify, the amount of condensate can increase, which will further enhance corrosion. Moisture will accumulate in the places where the rubber seals and the aluminum frame of the rack mate. In these places, violation of the working surface is not permissible. If oxides and corrosion appear on the working surface, a repair kit consisting of rubber seals and ensuring proper tightness will not perform its functions. Tuareg air suspension repair

If the leak persists even after replacing the repair kit, the only way to solve the problem is to replace the air spring. That is why it is not worth delaying the repair, because you can do just by replacing the "rubber bands". For clarity, we post a photo and a couple of drawings of the air suspension device.

What parts the air strut consists of - you can see in this diagram: Tuareg air suspension repair

On the right parts of the figure (also, the replaceable is highlighted):

1 - Support
2 - the O-ring (it is obligatory to replace)
3 - the Valve for maintaining pressure
4 - the Cover
5 - the outer guide
6 - Cover in the form of a sleeve element
7 - the Piston
8 - Cover
9 - Latch preventing pulling off (must be replaced)
10 - the O-ring (it is obligatory to replace)
11 - the Shock absorber

As you already understood, the repair kit consists of 2x supports, 2x clamps (preventing pulling off), 2x O-rings and 2x lip seals. In order to change this entire kit, you need to do the following:

  • Remove both front wheels
  • For right-hand pneumatic strut of diesel vehicles
    - Remove the fuel filter above the pneumatic strut
  • Disconnect the shock absorber control cables
  • Unscrew the upper struts fastening nuts to the body
  • Remove air from pneumatic struts
  • Unscrew and disconnect the rod of the body position sensor
  • Unscrew the air line from each air strut
  • Unscrew the ball of each upper arm from the steering knuckle
  • Unscrew the stabilizer struts at the point of attachment to the stabilizer
  • Remove the brake pipe mount from the steering knuckle
  • Unscrew the steering knuckles from the lower arms
  • Remove the air suspension strut
  • Disassemble the air struts using a special tool
  • Replace O-rings and bearings
  • Assemble the air struts and check the tightness by applying a small amount of air to the cylinders using a soap solution
  • Assembly is carried out in reverse order, taking into account the requirements of the manufacturer.
