Hi All,

I have a 2009 Porsche Cayenne GTS. The chasis warning light came on. Send it to a Porsche specialist, the fault code was FA valve block. So, i changed the valve block. The warning light went off for a while but the warning light came back recently. Spoke to the Porsche specialist again, he told me it could be the PDCC control unit fault. I bought the control unit and try to fix the problem myself. I am trying to locate the control unit in the car. Does anyone know where is the PDCC control unit located?

Rgds,

Jon

You are really going about this repair the wrong way. You need to verify the fault instead of just replacing parts. Have the vehicle check for fault codes, write them down then clear all codes and address any that return.

My Cayenne is blinking the "Chassis system faulty" on any rainy day, but there isn't any fault codes. I'm taking it to official service tomorrow (again), but I guess it's difficult to fix. But still - it's quite annoying to bring it there again... and again... and again... and again...
