The rain, the battery running down, battery cables, kill switches, fuses, relays, DME, Immobilizer, Key RFID, etc None of that had anything to do with it Shortly after I bought the car I installed a traqmate system, including a traqmate USB to control the cameras and data acquisition. That system had been in the car for nearly a year prior including 2 or 3 event weekends with no symptoms whatsoever. There was a pin on the traqmate usb labeled 5v with the input analog pins. The documentation. Is poor, so I hooked up 5v off the obdii port after having found you can get 5v off of there (I don't remember how that was determined, probably internet) I eventually had to buy a street car to have a known good reference. She showed up late last week and was keen to success. After checking things back and forth between the street car and the Spec Boxster, including triple checking the DME. I decided some input to the DME must be wrong and is causing the DME not to let the car start. So I wrote out all 88 pins and made a chart and one by one probed each signal in the street car, and then did the same in the spec boxster. After probing all the signals between the street car and spb I noticed only a couple differences, one was the software voltage pin which only connects to the obdii port. Street car was 0v, spb 5v. Also the durametric could talk to both dmes, but on the spb, all live data was defaults and voltage was 0v, regardless of the DME, while on the street car with both DMEs I got live data. I went home and thought about where the 5v could have come from, and I remembered the traqmate usb had a 5v pin. I also remember sourcing that 5v from the OBDII connector as that is what I had found online to do. My spidy senses were tingling -- was I on to something? About midnight last night, I found some documentation online on the old traqmate system. It wasn't very good, but I could see a photo of the pins labeled on the USB box and blew up the picture. , It wasn't clear, but it looked like 5v was an output Not an input!!! I had figured at the time that the 5v was needed for the analog data acquisition, not the other way around. Surely it couldn't be that simple. After a sleepless night I ran out to the shop this morning, unconnected the traqmate usb And she fired right up Motherf@cker!!! I think the 5v put the dme into some sort of program mode or something, disabling its ability to start the car. Why did jumping it work without battery? I think once you got 14v, the 5v wasn't high enough to put it in the program mode... I also think that once you get running, the DME just does its thing -- OR, the Boxster's alternator put out 14v, and once again the 5v input was read as a low, not an assert. Further complicating the matter was the small fuse box that was added for accessories that I had tapped off of for the traqmate 12v hookup is janky, and I don't think it has a good internal connection. That's getting yanked and a new, and more accessible unit will be installed. Just diabolical.... Now I have to put it all back together and get my medical done and sign up for NOLA. Thank you very much to all who supported my efforts and responded to my posts -- especially Ahsai. If nothing else, the moral support allowed me to just keep plodding along.1 point
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!1 point
