Psm Warning And Air Suspension Warning This Morning


Recommended Posts

I've got a 2004 TT -- this morning (an unusually cold/drizzly morning here by LA standards) i went out and got a mile away and the warning light for AIR SUSPENSION appeared. then, the PSM Workshop triangle w/circle appeared.

the car can barely pass over speed bump and looks like a low-rider.

i'm am about to sell this car and don't want to put another penny in to it--is there an easy answer or explanation for this?

i'm amazed at the number of problems that have popped up exactly after the warranty -- i am a long time Porsche owner and fanatic and this may be my last car given this appearance of unethical treatment of its customers.

problems like this suspension issue, or the horn that doesn't work, or other mechanical issues that should be covered by the factory and are no longer covered...just keep happening and i'm very disappointed in Porsche. let's hope they get their act together.

Without putting the a Porsche tester (computer) on it - it will be hard to tell.

I noticed the air nozzle port -- located on front passenger seat next to storage drawer) was uncovered. i wonder if somehow something started draining the air from the compressor storage tank - if i recall, this nozzle leads to the tank that keeps the suspension loaded.

if this is the case, couldn't i hook up an outside air source and add air to that tank? certainly don't want to blow the thing up :)

NO absolutely do not do that

Without a valve inserted thats not going to leak.

I had that a few time, each times it went away itself until the last time when the compressor was replaced. My guess is it may have corrected itself, if not Loren is right you need the error codes from PIWIS

Mine lasted 3 years

Sometimes a leg sensor can throw the computer off. Its amazing what a couple of restarts can fix on the Cayenne

The plot thickens--i went out mid-day to my very low-rider TT, started up engine to see what would happen and sat there and the suspension slowly started to re-inflate and get back to normal levels.

i have no idea how long that will last. will take to dealership this week.
