Really? The TCU lives inside the gearbox. If they did 'bench' it they would have needed to first remove the gearbox, remove the TCU then bench it, re-install the TCU and re-install the gearbox.
If this is the case then its the only dealer I've ever heard of doing it, plus dealers dont have the facility to bench the TCU unless they made something up, again I'd love to know what exactly.
Chances are they just re-programmed the TCU insdie the car with the MUT3. Seems muce more logical.
i really have no idea, since i was not on the site...
i heard from my friend that he was seeing the dealer pulling a lot things apart, but he doesn't have any idea what those things are. he is the owner of the car, but he doesn't know much about it ...
