  1. I intend to continue driving mine with the tick until it fails (I still think it might go a long time). I will update this thread if anything changes.
  2. Bringing up this thread again. I have a new to me '05 Cayenne S with 200,000 km on it. It is noticeably "ticking" away. I don't have any maintenance history, but it "looks" well cared for. My questions is, has anyone ever NOT replaced the engine? Mine is not consuming oil, I notice no driveability issues. It's just noisy. The cost of an engine replacement will be well over the price I paid for the vehicle, so I intend to keep driving it. Has anyone had a major failure after their ticking started?
  3. Since removing the left footwell and temperature mixing actuators, and opening them up and trying to push them around a bit for better engagement, the temperature mixing one is still acting up, so I will be replacing it. Good to know that the later model years are improved and compatible.
  4. Bringing up an old thread as I think I may have something to offer. I've been searching for info on this problem for the past week and currently have my dash ripped apart - which is amazingly simpler than I expected. If anyone has questions about pulling it apart, feel free to inquire. Anyways, I have not come across anyone offering a reason for what is wrong with the actuators, so after I had my footwell actuator free, I let it dangle (while electrically connected) and fired up the truck (didn't fire up the first time because the KESSY unit was disconnected). I could see the actuator was buzzing away, but the arm wouldn't move. After taking it apart (see photo) and manually spinning the worm gears by hand, I verified that nothing was seized and I already knew the motor seemed to be working from the buzzing. I then reconnected the actuator without the cover in place and I could see that the worm gear coming directly out of the motor was spinning, but not engaging with the straight gear below it (top right corner of the photo). After pushing down on the worm gear a bit it engaged well and everything was working again. I have only had the Cayenne for several months and I could hear the actuators acting up on the test drive. The seller played dumb saying he had never heard it before (can't know for sure if that was the truth), but I suspect that over time the motor may burn itself out cause it keeps trying to open or close the arm. If that is the case, if you don't fix it soon, it may need to be replaced, but I plan to put mine back in the car and save the $150 for a new one.
