We have just picked up a T30 - 6.1 DSG as brand new from a professional camper van converters. When driving there seems to be virtually no engine braking and it's worse when going downhill, almost like knocking a manual into neutral. It means using the brakes constantly - not my style of driving and is most unpleasant and potentially dangerous to drive. I could imagine on icy roads this would be much worse. For a brand new vehicle costing as much as a deposit on a house, surely this cannot be correct. I contacted the VW commercial garage who told me I would have to pay for a diagnostic check up (probably about £200). Has anybody else experienced this on the new 6.1 and if so, perhaps VW should be made to recall the new vehicles to put this right
