Up for sale is a BOSCH Throttle position switch. Good used condition.  I did the BMW Bentley manual checks, and this unit checks out functional.  0 280 120 206  Fits a variaty of cars, Saab, BMW, etc.  Check your original part number to be sure of fitment!  Part number is stamped on the back of your BMW's TPS.  BARGAIN ALERT for a good functional TPS.

Works fine and comes with a 30 day warranty.   You can still buy these new, but at a cost of nearly $150 they are rather unaffordable.  Thanks for looking and good luck!
