I have read and read and read the forums, and searched on line for a solid week now, and I cant find it. Where is this part at, I was told that cleaning this should fix it, because of all the possible crap that it can collect. I have to electric solution that should dissolve the grease and gunk but I cannot for the life of me figure out where it is at.

 

I was reading this thread to hopefully get some help. I need to clean or change out my tps on a 2000 A6 avant Quattro with a 2.8 automatic. Where do I find this sensor

 

Isn't your car too late to have a throttle position sensor? i.e. it's built into the throttle body itself? That's what I thought.

What error codes are you getting?
