You might be able to get away with The switch that I got from Camelback VW to replace my broken one did not mate correctly with the cam on the throttle shaft. I asked for a different one, but was told that there was only one part number and that it was the only switch available. I asked about getting a new cam and was quoted the price for a new throttle body because the only way to get a new cam is to get a new throttle body(insert angry, confused looking emoticon here). My solution was to build up the cam using epoxy putty. It works now, but I am not confident that this is a long term solution. > tweaking the arm on the switch to compensate for a worn cam (I've done it a > few times with success). I hate the thought of spending 30-50 dollars for a new part and then having to attack it with a pliers to make it work. I think that selling the switch without the appropriate cam is not in the best interest of the consumer. >I have the throttle position switch available if > you need one.
