    Default WK2 - Quadralift / Air Suspension

    I have a WK2 overland 2011. I can hear the air compressor kicking in far more frequently. It seems that there might be a small leak, and the compressor is then over compenstating to keep vehicle at correct ride height. This could either be a small leak in airbags, or o ring leak which these are prone to. Anyone else had a similar issue and if so, where were you able to have it repaired? I occasionally get a warning message " Air Suspension System Cooling Down, Please wait"

    Hi Rick

    I have had the "service air system" light pop on once when i was really working the jeep hard in the dunes, after cooling down it never popped on again. I have done allot of reading on these systems and failures do happen, yours sounds like a leak.....id take it to a specialist air bag shop to locate the leak.....mine makes no hissing at all.
