Well, I had to bite the bullet and buy the TPS from Porsche. I sent my broken part to Tom who confirmed I had a really bad part, both the idle microswitch and the pot tracks were dead. At least he has an old broken one on hand to use once he begins his engineering magic to figure out how to bring ...

walfreyydo thanks for the information. I will do some research on this just in case I must do throttle body modification to get the 951 up and running. thanks again.

MoeMonney, thanks for the post. I checked it out and the cross reference to a Bosch part on their site and by what I can see, it does not work on the 951.

So Johnb, for a potential substitute TPS ...

Ok, thanks. I tried to find tech specs for both the original and this one to see what was different/same to determine fit/form/function but was unsuccessful.

Hi all, after following the CARPOKES testing procedures, I determined I need to replace the costly TPS in my 951! Does anyone have any knowledge if this TPS for the older Audis, Bosch part # 0 280 120 431 could be/is a direct fit the Porsche part 951 606 113 00/ Bosch 0280 120 400? While cheaper, it ...
