I have a 03 636 and I need a sub throttle position sensor. This is just the little one the attatches to the upper butterfly valves on the side of the throttle body. It is a very small sensor however the best price I could find is 103$ on a website. If someone has a used one and is willing to sell it I'd appreciate a reply. Thanks.

 

Check ebay. You should be able get one cheaper.
