View Full Version : I'm lost, can anyone help me out? Replace TCM..

Hello everyone,

1999 Audi A4 Avant 2.8L Auto Tip Tronic 153,000.

My TCM got soaked because the drain under the battery got stuffed with leafs. I replaced the TCM with a working TCM and keep getting the following code after a couple cycles of shutting the car on and off. It doesn't happen right away but sure enough it comes back every time. It throws the transmission into limp mode and all the gears light up solid red on the cluster.

The one and only code I'm getting:
supply voltage terminal 30 31-00 open or short to ground under the TCM.

Does anyone know what this means or where to start?? Any help would be awesome!
