RE: Adaptive air suspension system active warning light. Managed to get a full diagnostic scan done and it seems that the Solenoid valve block has a possible blockage causing the rear suspension not to lower, in addition the air pump has been damaged from constant activation.
I am told that parts and labour cost for this is circa £850!! PS: Only recently changed the Intake manifolds, EGR valve and Throttle valve which drilled a very large hole in my pocket as my warranty company insisted it was down to wear and tear attributable to a vehicle of that age. They bluntly refused to cover the cost. My Q7 seems to be costing me a lot of money, beautiful drive, all mod cons but mechanical parts and electronics seem to be of poor quality compared to its BMW and Merc counterparts. Quite disappointed
