Hi,

My 2005 Passat TDI is throwing a P2100 code (TAC Motor Circuit Open). Does anyone know what this is and how to fix it. Car has close to 200k miles on it and seems to run fine. Any ideas? I have a handheld code reader and have cleared it a couple of times but it does come back.

I think it's something to do with the throttle valve/flap acting up, a quick google of the code suggests the flap may be stuck open or something.:)
