A month ago I bought a Audi A7 11' in Germany.
After a few days I realized that are some problems with the AAS in dynamic mode.
When I'm leaving my car and come back 1 or 2 hours later, the rear of my car is going down. It seems like that the compressor has some problems.
It is not my first day to work with vcds, but the error memory is empty.
When I am checking the "Stellglieddiagnose" it seems that everything is o.k.
I asked the guy where I bought my car, he tell me that is normal. I asked Audi and they tell me the same answer.
Now I'm driving with 19' rims, but in Summer with 20' rims, I don't think that will go well.
In other modes like comfort or automatic I don't have this problem.
I'm sure that is 100% not normally.
A minute later after I close my car, the compressor is working a little bit and the rear is going down about 1cm. After that the air escapes slowly.
You have a central compressor leak. You need to get it replaced.
I've did a scan today since I've received "Air Suspension Fault" in the dashboard and here is what I've found below.
The behavior is that if I let the car on normal mode the whole back of the car will go down in a few hours.
If I lift (raise) the car suspension before turn it off it will stay lifted.
Might be the air springs?
Thanks.
