  1. As it turned out, a part of the TPMS was loose inside the tire and was bagging around at low speeds against the rim.....GR
  2. My new to me '09 GTS Cayenne with 15, 000 miles has a banging/knocking sound coming from the rear at speeds below 15 mph. It s very similar to the sound I had on my 997s when the welds on the sport exhaust broke. I almost sounds like a rock in a hub cap. Any ideas before I take it in? ...Thanks.
  3. So I just bought a CPO 2009 GTS and from what you are saying it still has plastic pipes. Why didn't they just use the metal ones that appear to be everywhere now, If they are still plastic, how reliable are the later models with them? Thanks....GR
  4. I had the same issues this weekend for the 4th time. It fixed it 's self and no fault codes where to be found by my shop. The did reinstall the software and it runs better now that before the incident. I wish somone would/could fine the cause if this issue as it has been reported for years.....GR
