Like many other individuals that have posted to this site, I am experience problems with my '04 Allroad's air suspension. The right front suspension seems to fail when the Allroad is left in my garage overnight. This happens sporadically, sometimes for a few days straight, and other times only once or twice a month. Curiously, it only seems to happen in my garage (which is on a slight angle because of the floor drain) and does not happen anywhere else where the car is parked for equally long periods of time. Reading throught past posts, I assumed that I had a small leak in the air bladder that would begin to get progressively worse. However, the strange thing that appears to be unique to my situation is that the bladder refils (and the car lifts up) when you open any of the doors -- even if the car is off. My mechanic (an Audi specialists) states that the pump does not run when the car is off, having just witnessed the car's self correction, I do not hear it engage. Instead, I just hear a "whoosh" of air in the front right wheel well, almost like a ballast has been released. I'm stumped. Anyone have any thoughts? I've speculated that it might be an electrical issue or that some "controller" might need to be replaced. Or is this just a run of the mill bladder leak. Your opinions are appreciated!

 

he is correct the pump does not run but there is still air left in the tank and will correct its ride height when the door or hatch is opened

 

white fish is correct, got to answer you first. My Arnott Industries front air suspensions have been installed by my local mechanic and are working perfectly. If your allroad needs air suspension replacements, Arnott will serve you well.
