is the 4mo drive by wire?
if it`s drive by wire, the brick on throttle method wont work anyway..lol
also if it is drive by wire then i think vag com WILL be needed to re-align the throttle body.
if it`s cable then it should self adjust, what i did was disconnect the battery for about a minuite, reconnect it, then turn the ignition on but DO NOT start. you will hear the stepper motor in the TB buzzing while its adjusting for about 30 secs (guesstimated) then start the engine once the buzzing has gone for it to calibrate. Thats only if its cable of course and seemed to work on my AGU.
