Hey all,

My transmission seems to be in limp mode, It's stuck in what to seems 3rd gear. It has reverse, slams hard in forward or reverse. Engine light is constantly on. The really interisting thing is that the cluster does not show any gear display at all! No PRND, nothing. And when I turn the car to thew on position, It says "press clutch to start engine"!!!! and it's an automatic. Im way stumped.. Has anyone had this before?
Oh yeah, I started the car for the first time in 2 months and it would not go into any gear at all.. It had to idle for 10 minutes, then it started to move.. I
It's just the wierdest thing that the digital readout tells me to press the clutch to start the engine considering the fact that it's an automatic car with no clutch..

Iv'e spent alot of time reading up on the forums about tiptronic transmission issues and found the 3rd gear thing, but not the cluster issue or anything else..
What's going on?
Thanks

 

I should add that the inside of the cab has been wet... It looks like there has been water under the carpet! If this TCM has been severly damaged is it possible to short out to the poiunt that the display on the cluster thinks te car is a manual?

 

Well if you are lucky, you can pull out the TCM, dry it well, and may work fine.

 

I am in the process of fixing an 02 A6 that had gotten water in the tcm and it did exactly the same thing it gave me the same warning about pushing the clutch in I had to replace the module and all is fine now.

 

yup pull up the carpet and hit that thing with a hair dryer, i'd disconnect the battery ASAP. Wet electronics are typically fine as long as they are not exposed to current

 

Well you guys were right on the money!! I pulled the carpet up and long and behold, (2" of water in the black box)!! Now Im thinkin oh crap.. I pulled the TCM apart and it's destroyed. I need one now and the local dismantler here says it's a TCM for a 2000-2001 A6. My car has a build date of 3/99. Does anyone have a spare? TCM part number 4B0 927 156 CE

Thanks

 

Yeah, alldata has a TSB or recall for that, I forget which. Someone posted a .pdf of a letter they got as well. I went to a dealer though, and they claimed ignorance.

 

But of course!

My audi dealer here in Sacramento said "huh? Water in where"?

 

If you cant find one locally locally I have had good luck using the site - www.getusedparts.com just enter your car info in and usally within a few minutes you will start to get responses I wouldnt enter your phone as it will be ringing for hours if you do lol.

www.shokan.com is another source but they are a little more pricey than what I found on getusedparts.

I found both my tcm and my central locking module on there within a couple hours of posting what I needed.

 

Does anyone know where the TCM fuse is located? all the fuses in my fuse panel on the side of the dash are good...
