Robin, as you have such fast road/track experience, have you noticed anything similar if you, for example, had to hurry a shift into a bend?
I wonder if it's worth polling the DSGers amongst us regards hesitation (in auto mode) as I described.
....I don't have a lot of track experience - Some, but not as much as many here. But I do have 90k miles of DSG experience in my GTI.
When I first had my DSG way back in 2005, I didn't feel comfortable with the small plastic oem paddleshifters and drove for several thousand miles in D but always used S for overtakes and a series of spirited bends. I've never liked the feel of nudging the floor stick and have only used that method less times than I can count on one hand. In reaching for the floor stick I find it natural to expect a gate.
So, at around 6k miles my Mechatronics module hiccup'd and VW replaced it under warranty although there was only one incidence and the car drove normally straight afterwards. I have experienced, like many others here, clunky shifts but they have invariably been down to cold temperature. I now always let my engine warm up so that the revs drop before I engage any gear.
From time to time I have experienced hesitancy but only in D or S and it has always seemed to be just a delay on gear selection probably down to the DSG brain momentarily being unsure about what my right foot was asking for. It has always cleared up after a few miles of 'retraining' - The DSG 'learns' your driving style.
Since Revo remapped my DSG box, none of these problems have occurred except for the cold temperature
IF I don't settle the engine first.
I hope this helps in some way
