I just purchased the car used with a 1 year warranty and it has some issues. I'll separate them and address just one here. The air spring system is nuts. I hear the air pump in the back often when I start up the car, but there's no rhyme or reason or recognizable pattern to it. Sometimes the "Self Levelling Suspension" light comes on and then just stays on. Then it's off for days. If press the raise/lower buttons, at one point it was trying to raise. Tonight it didn't even try. Does anyone have any idea whether this is likely the pump, a module or the springs leaking, or all of the above? And, yes, yes, I'm considering the conversion kit. I'm new to Audi ownership (former Saab Sportswagon owner (LOVE)). I know that as soon as I get a moment, I'll take it to Auto Zone to have the codes read. I think they'll do it for free. The dealer charges $130.
