Audi a8 adaptive suspension problem
 

I noticed that my audi a8 adaptive suspension is now stucked in the lift mode (as the little light on the dash board indicates).
On MMI screen it does not let me to change it to dynamic, also while driving above 80 miles it did not drop the car down.
What can be the problem?
Thank you,
A.

You will need to have the car scanned to see what the faults are in the suspension module. Without that for a start , everything would be just a guess.
