Audi 20 valve throttle body, with TPS  Up for sale is a Working, in excellent condition Audi 20V throttle body with TPS.  Has a good condition throttle position sensor!  This is the rare bit... Only used on the 2nd year of the 2 year car as far as I am aware... a LATE 1990 90, 20V will use this, as well as the 1991 model year 90 20 valve will use this, the TPS is very expensive to buy new, and about as rare as hens teeth.  You need a good used  0 280 120 422 / 051 133 154A TPS?  You found one!  here at epartsland.com.  For a while I had a 90 90 20V, quattro as my daily driver, I had a hell of a time trying to find a good used TPS - my original on the 220K 1990 90 had physically fallen apart! and they run pretty shitty with no TPS signal.  Then one day, I found 2 of them!  This is my spare from "the personal collection"  I know, this is not cheap... but I only have just this one!!!
