2005 Porsche Cayenne Turbo Q&A
2005 Porsche Cayenne Turbo Question: air suspension warning lights comes on after the first start.
You may have a leaking air shock, that sags over night. Every time you start the engine the air suspension does a self-test and the suspension pump runs to level out any of the shocks. If a shock sags too much because it is leaking air, then this will set a code and turn the air suspension light on for awhile. - dandd
