Hi i ordered some type of so called chip for my 2000 passat v6 and its supose to go on the iat sensor im not sure where and how this would work. has anyone ever done anything like this to their passat i could use some help Thanks.
Thanks for the reply yea i paid 20 bucks for it thought what the hell lets give it a try i unpluged the wires from the intake and plugged the two pins at both ends but when i did that i could hear the little air pump next to the intake kind of kck in sounded like a small compressor is that how it is supose to work
The intake air temp sensor is in the intake air duct at rear of the intake manifold. Sounds like you activated the secondary air injection pump located on the lower front right side of engine. It should only run for 20 seconds or so on cold start.
