On my 2002 TT the module went bad. Dealer pulled the white wire I believe to get it to run, all safety switchs didn't work though.
The S/N would be helpfull to look at a diagram. Guessing most years are the same but never know.
Looking for blown Kawi 29HP DFI engine's fd791d, whole thing, intake, throttle body, and electronic's. PM me if you have something you would like to sell.
