I find it strange that VW cant get the DSG boxes ( mechatronic units ) right after all these years. They must subcontract these parts, and charge the supplier for the failures. It must be costing a pretty penny.
I have had 3 new VW's and the mech unit has been the only fault.
Still, wont be long until you can enjoy the car again, at least it is nice having a warranty with no quibble for these parts.
