Does anyone know if Transmission Control (Module/Unit) 3B0 927 156 CF and 3B0 927 156 AP are compatible? I have to replace a "CF" and have found an "AP". Any real difference between these?


Thanks,

I'm sure you will score a "CF" on this site, many members have installed 5 or 6 speed manuals when the auto fails. As I know it "AD" up to 04 1/2 and "CF" 04 1/2 on. I've used a "AD" in my 05.

Did you find one. My 3B0 927 156 CF tcm has been sitting on my desk since Feb when I had my swap done.

Found this thread after being gone for a while - I also have need for a 3B0-927-156 CF power train control module for a 2005 VW Passat TDI.

Shout out to Afarfalla - had TCM issues with my 05 Passatt. He passed on some great tips and supplied me with a “CF” TCM for my TDI. Car is up and running again and good for several more years.(y)
