Replying to: Brooksman (Jan 14, 2009 10:58 pm) It would seem if the problem was the transmission, and 1st gear was gone, we shouldn't be able to get the car into 1st gear at all - regardless of what we do to the car or under any condition. We can get the car into 1st gear by pushing or rolling the car to reach a minimum speed of about 5 to 6 mph, at engine idle speed. In tiptronic mode we can run it up and down from 1st to 5th, no problem. If we stop with it locked into 1st gear, we are good to continue on, but if we stop with it in 2nd through 5th or in drive, it's back to no-go. For as rough as the roads were, we are leaning towards thinking it is electrical, as if a wire or connection has come loose. Again, we will continue to post our findings, and hope it is helpful to others or maybe someone out there someplace has gone through the same situation and has a suggestion or two before we part the car out, spend $$$, or the guys with the white coats come and take us away.

Replying to: Brooksman (Jan 14, 2009 11:28 pm) Changed transmission oil - no difference. Did a diagnostic check but got only readings of "no fault codes", with the exception of "brake light switch - implausible signal". Still trying to work through the electrical diagram to get a better understanding of the wiring. The brake light switch does connect to the transmission control module and the purpose of this switch - to our understanding, is to allow the gear shift lever to move in and out of park. This was not a problem - the brake light switch seems to work properly. Is it possible the brake light switch controls more than the gear shift within the control module? During the oil change process, all but one of the solenoids in the valve body were physically removed and checked. The one we did not check was not removed due to the location of the solenoid. During the diagnostic process, all of the pressure switch solenoids and shift solenoids seem to be working as we hear an audible "click" on and off as it went through each of the solenoids. At this point we are considering one of three possibilities. 1) A bad speed sensor within the system. 2) A bad wire or ground connection or 3) A bad transmission control module. We are steering towards the bad transmission control module, since we worked through the diagnostic process, the readout gave no fault codes other than the "bad brake light switch". Has anyone come across any other possibility? Again - we will keep you posted.

Hello, My husband just bought a 2005 A6. He filled up the gas tank 2 days ago and it still shows the needle as empty and it says he has 0 miles left in the tank. The tank is full. Has anyone ever had this problem? Thanks! Hunter
