The front valves of back pressure (gearboxes) rot and start to lose an air. It must be replaced or try to clean. First, air suspension line (tube) is removed, the valve around is cleared of oxides.

How much nitrogen is in the VW Touareg receiver?
Usually, 12.5 atmospheres of air or nitrogen are pumped into the system, depending on how the sensor is configured in the car. In the old models of the VW Touareg, nitrogen is not pumped, their air suspension system is not designed to use nitrogen. But in the new VW TouaregNF models from 2010, nitrogen is pumped in, as it is provided by the plant. It is pumped according to the standard value of pressure in the air suspension system – an average of 12.5 atm (12-13 atm).
What is air suspension and shock absorber?
Air suspension is a shock absorber with a pneumatic baloon installed on it (instead of a spring) and performs the function of maintaining a certain level of the vehicle body relative to the roadway. This is made possible by changing the pressure in the air suspension.
A shock absorber is a device used to dampen vibrations, as well to absorb shocks and hits of moving parts (wheels and suspension), and the vehicle body itself.
What’s air suspension valve for?
A back pressure valve is usually installed on closed-type air suspension supports in case of a broken pneumatic line (pipe) or any other leakage so that all air does not come out of the air suspension cylinder. Otherwise, all the air will come out, and the rubber sleeve will bend, and it will simply tear it off with the details of the air suspension itself.
But in this case, there will be 5-6 atmospheres of air in the air suspension, and it will work in the normal mode. The pillow will still get on the bump stops, but the sleeve will be filled with air, so it will not tear. But if leakwill happen in the cylinder, the valve will not save. Although, in practise happened that the valves on the front cylinders of the Tuareg fell off, the air suspension was chewed, but whole, without a break.
