Spice D Posted May 15, 2023 Share Posted May 15, 2023 I’ve not long bought an Audi Q7 2009. The yellow warning light comes in after a few mins driving. When I start it things work perfectly at all heights but then it drops into automatic and the light comes on. I think….it’s front left that’s the problem. I don’t have a diagnosis tool yet and I’m in free fall panic that I’ve bought a pup. Cars done 134k and otherwise perfect so far. Please be gentle ! thanks Dave Quote Link to comment Share on other sites More sharing options...
Magnet Posted May 16, 2023 Share Posted May 16, 2023 Hello Dave, Possibly a failing compressor, but could be a number of other causes. Your best (U.K.) friend for air suspension systems is Bagpiping Andy - you’ll find him via. a Google search. He does new piston rings for the compressors, and much more. Kind regards, Gareth.
