I think my wallet is about to become a lot lighter. Got up this morning to the passenger side front suspension dropped to the wheel, the car on a slant. Switched on engine, compresser has pumped up the air suspension and it stayed up, as long as the engine is running, I can't hear the compressor constantly filling the air bag so assume its not a "leak"? Any ideas what it could be? Its safe to drive just panicing that I'm about to get a massive repair bill.
