Not today, but on tuesday I can use the workplaces one, what am I checking so I can let you know how things go, also a quick question theres a wire at the bottom of the TB, has 8pin holes, but it only has 7 pins, is that the way it should look?

I think that's right, couldn't say for certain until i have one in front of me. Without checking wiring diagrams i can't say which wires on the plug you need to be testing, that's something you're going to have fun with on google :grin:

Have you tried going for a quick drive to see if it will adapt itself that way? Takes about 15 minutes of driving i think.

Also did you have either of those error codes before you took the throttle body off?

I cleaned the TB a week ago did some heavy right footing, still the same old stuff. My friend suggested I reclean the TB again incase something is caught on the sensor as well as clean the contacts, did it again today, still same problem, but them error codes are new as I only scanned yesterday and they did not exist.

Going R-tech in October  maybe they can help?

either wiring issue or broken potentiometer then... r-tech will probably have a spare throttle body you can test to try to eliminate the possibility of the wiring fault, but if you're going for a remap you really want it sorted before then.

think its advisable for me to dismantle the tb and have a look as VAG COM shows voltages or should I not go by them?

ahh so you can still see the voltage, i didnt realise.. thought vagcom was kicking you out completely

its sounding more and more likely that your potentiometer has had it. you can try taking it to bits but if you can't get it back together then you're stuck without a car unless you can get your hands on another tb... should be able to pick one up from a breakers, or someone on here snagged one from ebay recently pretty cheap.

thanks for that, is the potentiometer located in the TB or is it else where?

its on the tb.. you can't buy it separately unfortunately, i've had broken ones in pieces before (albeit from a dbw model) and there doesn't look like there's anything in there that you can repair. You might be better off leaving it as it is.. while it's still drivable.. until you get your hands on a replacement.

you say its a small piece its not that thing that directly plugs into the tb, looks like two fine wires?
