ya got me there. TDI's don't have spoilers so I wouldn't even know where to begin with the sensor. Maybe it's a relay somewhere? either in the fuse box or steering column?
As far as the door microswitch....again no idea. lol I haven't had this problem as of yet *knock on wood* but I'm sure SOMEONE here has.
Congrats on the Tbelt and such being done. I'm sure you feel MUCH better knowing that Titan is good to go for another 100K on that!
I need to find a TDI guy who does Tbelts for that price lol
