My friend's RS6 has a transmission fluid temp sensor code.

We replaced the wiring harness in the trans and it still pops the code time to time. Does anyone have a TCU that we could borrow to test it if his have a problem? If the swap would not fix the problem then the wiring between the TCU and the trans plug has a ripped wire somewhere.
Thanks in advance!

I have a spare tcu...It does have a MTM chip soldered in.

Thanks Kevin! Would you mind lending it to us? His TCU has an MTM chip in it also (or we think it has).

You may use it.
