The argument for the 7speed dry clutch was for energy efficiency re transmission power loss compared to 6speed oil clutch .
With 7Speed Golf clutch, had several occasions where DSG suddenly disengaged (due to over temperature? while slowly into position uphill)
However re the 6 speed DSG fitted to my Passat, this is so much better than older cars I have driven with conventional torque converters. Unless one watches the Tacho' one is not aware if any change has taken place. BUT and I mean BUT, re BlueMotion, this is a Bugger. Many times I pull up at a roundabout then I see my opportunity. What happens? The car stalls at the most critical moment!
