Cayenne S Engine Codes

I recently purchased a 2008 Cayenne S. Yesterday the car took a while to start and had a very rough idle at approx. 400 rpm. The Check Engine light was on and when I read the codes I got:

Stored Codes:

P1372 Unknown Diagnostic Trouble Code

Pending Codes:

P1372 Unknown Diagnostic Trouble Code

P1353 Unknown Diagnostic Trouble Code

P1351 Unknown Diagnostic Trouble Code

P0174 System Too Lean Bank 2

The P0174 code is probably related to a bad O2 sensor. Does anyone know what the other "Unknown Diagnostic Trouble Code" are?



Thanks,

Terry Watson

I have a 2009 Cayenne GTS and the check engine came on with only one code P1372. I picked up a iCarSoft Por II scanner to get more detail. It reads. Valve lift control, bank 1. Ended up replacing the Camshaft Solenoid Adjuster. Multiple codes can mean something else.

P1351 - valve lift control, cylinder 1
P1353 - valve lift control, cylinder 3
