Indeed, air suspension can be a quite expensive repair. If the vehicle is, suddenly, not rising at all, it could quite possibly be the compressor, air lines or the reservoir as mentioned in another response. There are aftermarket options available that can represent a relative savings to rebuilding the entire factory unit but you may get lucky and only need a single component. While we do charge a diagnostic fee to explore system failure it would be applied to any repair we perform for you. Let us know if we can help!
Thank you! I do believe you can help. I am making arrangements to get my Audi to your location for a diagnostic evaluation.
Air suspension is normally an expensive fix. Could be a leaking damper, line reservoir or bad pump. If you don't want to take it to the dealer you might try Bimmer Rescue.
