Replying to: homeshop (Jan 10, 2009 7:41 am) The thought behind this is, when we can get the car up to 5 miles an hour (rolling it down a hill), in tiptronic mode, the car will smoothly shift into first gear, and from there we can drive the car and shift from 1st - 5th and back without incident. When in 1st - it will stay locked in even when stopped. BUT, if we stop the car in 2nd, we are back to square one and the car will not shift into 1st. Also, with the same start of rolling it down the hill, we can get it into "D" drive mode, and it is fine while in motion, but will go back to doing nothing when we come to a complete stop. See if this works for you. If you find the same results let us know, maybe between the two of us we can get these cars to work. |

Replying to: biglio (Dec 03, 2007 3:11 pm) Was this what happened to you? Was it your transmission? Did you have to have it replaced? Was it your fluid? Or I'm wondering if it will do this if the fluid is low or out? I have an 98 Audi A6 Quatro. It has over 200k miles. The engine was rebuilt at 100k. 3K to fix? Wow. I bought it for 3K from a dealer, it was a deal. I was very happy. exithour  hotmail.com Any info is greatly appreciated! Thanks! exithour hotmail.com

Replying to: clueless3 (Dec 13, 2008 8:36 am) Windows have issues too, The passenger window won't roll up in humid weather or rain anymore without great physical assistance. Not sure about my transmission now though. Today, it only goes in reverse. Just quit moving forward, except ultra slow. Bought the car for 3K. Totally can't afford a 3K fix! |

Replying to: 98AudiA6 (Jan 14, 2009 8:20 am) I checked with local transmission repair and depending on problem cost between $100 (doubt it) to replace a small component/adjust controlling computer, to around $3,000 to repair or pull/replace with used or remanufactured transmission. Both have limited warrantys. I called an Audi dealership. $6,800 to pull and replace with a new transmission. Good warranty, but no on sight repairs or lesser costs. At our Audi's ages, I can not see that money being well spent. Hope your problem is electrical - heck for that matter I hope our problem is electrical!

Replying to: homeshop (Jan 14, 2009 10:20 am) Wow! Thank you for all the info! I can only hope!! I love the car but... There's no way I can do 3-6K fix. Esp when the car was 3K when I bought it last year. I was told to tow it to a mechanic, have them check and maybe fill the tranny fluid to see if that was it. ? Then see if it'll drive. Then, I'll know more... When I asked, They said these do not have dipsticks for an under the hood layman checking. They have to be checked with some device at a certain temp. I'm not sure I'm equipped to do the small check you mentioned.-? I'm an unmechanically inclined single mom, with nothing but a tire jack and screwdrivers, parked in 0º temp and more than a foot of snow!  I tried to take the snow guard off once before, unsuccessfully. I think that may be in the way of this tranny fluid check too.

Replying to: 98AudiA6 (Jan 14, 2009 12:02 pm) We've changed the transmission fluid, and still didn't correct the problem. We had issues with the "check engine" light, and among all of our tests, we found the battery needed to be replaced. We swapped it out with another one, and found the small wire on the plus side of the battery was corroded badly. We replaced the end, and reattached it. The check engine light hasn't come back on. We found if you remove one of the wires on the air cleaner intake, it will make the transmission (in our case) go into fail safe mode. You can drive the car in 4th gear only - without having to making the trip in reverse. This has become a major source of frustration, but we're still in the search and destroy mission to see if we can get this fixed without the major $$$ a new transmission would require or taking it into a shop to have someone say "it's only a loose wire". We were able to do the transmission oil check and fluid change ourselves, but realize not everyone has the ability or the tools required to do so. We will continue to post our findings to assist others if this information is helpful as we have looked long and hard to find some sort of solution with little help and few results. It seems shops have never heard of our problem, though through this site we realize it seems to occur and not an isolated issue. Best of luck to everyone, and we will keep you posted on our results - hoping an answer will soon appear. |

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.

 My airbag service light just came on. My code reader will not read this type of code. Anyone else deal with airbag issues?
