View Full Version : OBD P2102 Fault Code

Hello Boys and Girls

I've got an Audi 2.0 TDi - 55 reg. (2005 - 2006)
I've got a P2102 Fault when i plug into the OBD port.
It does reset, but comes back up after a few mins of the engine running.
I've searched on the internet and it seems to be 'Throttle Control Motor'.
Can anyone advise me what could cause the fault and if it is DIY repairable.

Many Thanks

A vag-com read might give you a more accurate pointer. If the car is working it suggests that the throttle needs replacing because the ecu is getting a signal it doesn't like. e.g resitance or votage out of spec. That suggests that the throttle is struggling to open and close properly (needs cleaning) or throttle motor is dying.
