2005 Porsche Cayenne Turbo Question: air suspension warning lights comes on after the first start.

When not driven for a while then comes off after restart.when driven regularly the light doesnt come on. -
Answer 1
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. -

The car sits evenly even when parked for a while (a week or more) and no noticeable change in heights. The lights comes on when driving after this long period of unuse but turns off after a few re-starts. I did notice that the car don't hiss and lower or goes up after I park. How do I check to make sure the air suspension /auto leveling function still works? -
