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
