  1. My 2009 Cayenne base with 110,000 miles displays CEL and posts a P0674 fuel rail overpressure, implausible value via Durametric. (Unfortunately the actual vales are not shown by the software for the v6.) There are no problems with startup, rough idle, loss of power, etc. Just that annoying CEL. There seems to be a fair amount of conflicting interpretations of the P0674 on the web, and the absence of symptoms is puzzling. Before my questions, some history. About 14 months ago, I had what was diagnosed by a local shop as a failing PCV, requiring replacement of the intake man
  2. I appreciate the detailed procedure, but before I embark on this apparently fiddly project I hope someone out there could address a few questions regarding my 2009 Cayenne 3.6 did with 120k miles. I am getting a P0674 code from Durametric-which suggests the pressure sensor is supplying an implausible high value. There are no problems with startup, rough idle, loss of power, etc. Just that annoying CEL. There seems to be a fair amount of conflicting interpretations of the P0674 on the web, and the absence of symptoms is puzzling Why/how would a failing pcv valve cause
  3. I have reviewed the past posts regarding the high speed fan hack for the 986/996 by manually switching lug 85 to ground. What is the easiest/best way to tap that lug so I can run it through a switch, and what gauge of wire is called for? Thanks!
