A friend of mine has a AMG Mercedes CLS, he stated he has factory air ride suspension. I know this might have been answered before but I tried to do a search on it and couldnt find anything on it.

My question is: Is there a data system controller to lower the car w/ the factory air suspension? Can it be done manually as well? If so please help. Thanks.......

 

The CLS has multiple ride heights for different setting. ie sport lowers the car.
