Josh,

Something completly analouguos, that I know about. Does the TIS for the Z3 have the factory proceedure for fixing a cracked differential mount? I know that I've seen several where the dealer will weld a second mount over the first. However, it seems the dealer has to bring in an rep to tell them how to perform the repair, thus avoiding the documentation and resulting liability if something goes wrong with the repair. Maybe it's a similar kind of situation... non-documented dealer/factory repairs.
