hi guys, i have a problem with my air suspension. I replaced the air compressor 3 month ago and everything was working fine since then but 2 days ago i noticed when i was driving that the front was sitting lower and finally the red running gear fault appeared. I plugged vcds and i have some code, i will post it later. First it's weird because i can hear my compressor kick in and out , secondly when on park i can turn the knob to x-tra offroad and the front and rear go and but as soon as i go bask to normal the front go down completely and the rear move down just a little bit.

this is the code i have

hi, if the front is going down (or any corner is lower then others) and compressor is kicking in time by time i think it means there is some air leak somewhere, and its better to find it quick until new compressor overheats and toasts itself, please post updates, kind regards,

also i heard that air suspension needs calibration after repair

 

[Christ418]

But it was allright for the last two month and for no reason that started

 

[nikoloz]

try to find if you have air line leak where air line is connecting the air shock, its not very common but its the place to start form

 

[Christ418]

Im gonna go get some leak check and look at it

I tried the calibration but when i try to do the channel 01 my red stop fault running gear appear and everything stop. Now i am stock with the error 01437-control position not learned and i cant clear it because you have to do all 5 channel to clear it
I need help

If your VCDS is genuine Ross-tech's forum will help you. Register, then post a complete auto-scan.

[Christ418]
