  1. It is not DFI. The 4.5 litre engines are port injected. The 4.8 litre engines are Direct Fuel Injection.
  2. Thud could be centre bearing carrier for the rear cardon shaft. Whistle may be evident if your aircon servo flaps are closed. Try opening them by turning on the fan and having air flowing to the outlets.
  3. Good to hear you were able to "bend back" the finger. Do you have a scan tool handy in order to measure the #2 camshaft angle to confirm?
  4. Was your replacement actuator the same part number as the off going part ? If I recall correctly, there was a control module change requirement when the transfer case actuator was replaced with an updated part number.
  5. Yes, there is only one hydraulic chain tensioner for your Cayenne S 4.5. It is item 6 on the attached parts list.
  6. Put it in 3rd gear and do a full throttle sprint. You should see the boost gauge read 0.8. The boost / temp sensor located on top of the intake manifold just in front of the throttle valve is the sensor responsible for sensing boost.
  7. Control lines down to the wastegate actuators do crack / split preventing these actuators from opening resulting in overboost condition. N75 valve and boost sensor on the top of the manifold are also in the loop and are possible suspects. Below post is the troubleshooting guide for P0234.
  8. What code are you getting for the overboost? The thing on the bumper looks like some sort of radar jammer / light assembly item.
  9. I am not getting any ECU faults appearing with my dubious cam readings on bank 2 via Durametric. Car is running well with full boost. Any ideas? 2003 CTT - 260,000km
  10. The oil cooler indeed is water cooled. I had my oil heat exchanger changed on my 2003 Cayenne turbo last December as it was cracked with oil found in the coolant system. Change it asap. Part number for the S and turbo is the same being 948 107 276 03.
