I don’t think that is corrosion.
To day with hep of diagnostic technician, we open the cover for compressor located under the right side. The compressor is working and there is no lack. We try to disconnect the aire lines connected to the Main vale switch, no air is coming out.
When we connect the tire inflation system ( directly connected to compressor) we have a pressure of 3.6 Bar.
So, it can be the can be the main switch valve than can’t open, may be due to suspension computer problem or fuse , etc ?
I was confused the car is undriveable with very hard dumping.
I seems very difficult to repair as the diagnostic don’t deviler any information except low pressure. And VW Oman refuse to deal with such problem they have no experience on air suspension they recommend to change all the system for 5000 USD.
Is it possible to remove this system and put in place normal suspensions, how mach it will cost ?
Thanks guys
