Hi All, I'm new here, but found this thread very helpful. I thought I would sign-up and share my experience. My 2009 Cayenne V6 (left hand drive) has been blowing cold air on the driver side and warm air on the passenger side for the past 2 years. All passenger side vents (center right, far right near the door, and rear center right) would blow the same warm air not matter what. With summer coming up, I thought I better revisit this issue. After reading a bunch of forums on this issue, I came to the conclusion that - 1) I have the 2 zone A/C system (meaning I have less flap motors than the 4 zone) 2) it seemed to me that the front, right mixing flap was the issue. I began by taking off the lower passenger panel - its 1 screw and the glove box and a piece of triangular trim on the passenger side of the centre console (it just pops off). Once those were off, I could see 2 flap motors. One was right where the lower panel was and easily accessible - it was attached to a white plastic arm that it moved back and forth. I turned the car on and played with all the A/C setting and could see that that motor was working - it moved the white plastic arm back and forth.... (note, when I turned on the car, there were a bunch of dash warnings including low oil pressure - they went away once everything was back together) The other motor I could see was not as accessible. It was more towards the center and higher up. It was to the right side of the nav screen, inside the dash... I could only assume that had to be the front, right mixing flap. I decided to take a shot and changing it. I ordered: 1) 7L0-907-511-AL front, right mixing flap (10) - from Volkswagen. This is the equivalent Touareg part. 2) this ratcheting screwdriver tool: http://www.amazon.com/03044A-4-Drive-Mini-size-Ratcheting-Screwdriver/dp/B000XYOUS6/ref=sr_1_1?ie=UTF8&qid=1464195744&sr=8-1&keywords=Neiko+03044A+1%2F4-Drive+Mini-Size The flap motor only has 3 screws.. they were tough to get out. It took me about 1-1.5 hours to unscrew those 3 screws... most of the time was spent finding the right position to unscrew the screws.... and there was not a lot of room to turn the ratcheting screwdriver (a regular screwdriver would 100% not work). So once I would get the torx bit to connect with the screw..I had to unscrew very slow (shallow turns) and often drop the screwdriver. Annoying... and frustrating.. but keep at it. Getting the new motor back in was a bit easier and I had figured out the best position to deal with each of the 3 screws. Make sure the motor connect properly to the white piece that it controls. putting the new motor in was probably about 30min max. I put back the trim piece, glove box and lower panel and turned one the car... and cold air was blowing out of all vents! Glad that is dealt with!.. I almost have no problems with my Cayenne now... I suspect the rear hatch struts are due to fail next!
