  1. I believe in a 2009, you should have the updated style servo that was apparently more reliable. They are probably different part numbers than I used. I did find that the VW ones were exactly the same part number and a little cheaper. I also recall that the number and position of servos wasn't always consistent with the documentation.
  2. Hmmm... Didn't realize the foot brake pedal was on that side. I came across a couple people suggesting sliding the plate down, but I can't offer any comments on it.
  3. Now that you say that Heidi, it makes sense. A, B, and C are not possible to remove from the bottom (as far as I know). But I'm pretty confident that D is the one you want. I had what sounds like the same symptoms as you - no temperature control on the driver's side - and replacing D fixed the problem. You need to remove E first to get it out of the way. It is a terrible job, but I got D out without removing the dash. A tiny ratchet with the right Torx bit was an absolute necessity. Also, I think I used a right angle screw driver a bit too (like this https://www.amazon.ca/TEKTON-29
  4. It might be helpful to get an overall photo - it was tough to tell which way was up. That said, I don't think any of those are your problem, so it's probably on the other side. The third one seems that it may not be working great, but it is at least working. The diagram on the first post of this thread shows the left hand arrangement for a LHD; the mixing servo is "D". Maybe check out the right hand side and see if it looks similar to that diagram.
  5. I would dive into it a bit and you should be able to get an idea. Take the bottom kick panels off both sides and take a look underneath with a flashlight. I'd leave the battery connected and once you have the servo out, you can plug in the wiring again and adjust the temperature, then see if the arm will move. Also, I did not need to do any adjustments to put them in service position. Just pulled it out and then moved the flap with my finger so it was in the same position as the new arm I was installing.
  6. Heidi, I believe you are having problems with your mixing servo. If you can get air to blow at all your vents, but it's just the temperature won't change, then it is your mixing one. On a LHD, this is the second from the bottom on the left side and can be replaced from underneath, although it's not fun.
  7. 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.
  8. 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?
  9. 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.
  10. 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 wa
