Audi q7 2006 7 seater.Runs and drives been using it for the past few months.Put a new seat of tyres on by a mobile tyre fitter and since then the adjustable air suspension has stopped working.Called up the guy but doesn’t want to know.Apparently he should of put it in jacking mode when fitting new tyres but I’m unsure if he has or not.I’ve been driving it just fine.
