The Mechatroncis will have been re-set by a software download. I think the DSG has a problem either with its dual mass flywheel or with its first and 2nd gears. So to soften the torque impact on them VAG has introduced a deliberate delay into the throttle response. No such problems with Ford/Getrag's similar Powershift. I seriously abused one while filming and it still behaved impeccably. But what I don't know is whether VAG/ZF have discovered an intrinsic flaw with the system that Ford/Getrag have yet to encounter. No problems have been fed back to me about Powershifts that have been fitted to Focus and C-Max for two years.
