I bought used 2nd gen Cayenne under 2 weeks ago from the official car dealer. Now the car has blinked yellow "Chassis system fault" on yesterday evening and this morning. Is this "known problem in Cayenne" (that come up every now and then)? Or is this just bad luck? This is my first Porsche and it seems, that this "journey" didn't start well... but I really like the car, btw.

Any idea what could be wrong? Soon I'll be driving car to the Porsche Center...

That fault can identify a number faults - it is best to have the car scanned with the Durametric software or Porsche PIWIS tester to find the exact faults.

Thanks for the reply! Because there aren't anybody telling about "typical Cayenne error" - I suppose it's just my car. Service didn't find anything from the error log. Now I got the warning again and I'm driving service again. It seems that it is only coming, when it is a rainy day. Something don't like water. Well, I don't like the rainy days either, so I can't blame the car ;-)

My Porsche Cayenne also has the Chassis System Faulty error.  I never had anyone figure it out, the system worked just fine.  However, 6 weeks ago I took the car in to get an oil leak fixed.  I got my car back, oil leak was fixed but the Chassis System Warning light was on, not blinking off as before, and now my car has sunk like it has no shocks anymore.  The system totally failed.  The mechanic says it's the sensor that works the chassis system.  Can't wait to see what that is going to cost me........

That can be your air system failing.

What year is it, and do you also have PDCC? The anti-roll bars are hydraulic and the rear high pressure line failed on mine. It's a common problem, I was told. Do you have a leak in the area behind the rear axle?

Either way, you need to get to a Porsche-specific scan tool to identify the problem.

And your mechanic seems unfamiliar with these vehicles to just toss off a sensor guess. 

Get it scanned.
