I have the S-Tronic gearbox on my S3 and have had the following issue I would say around 3 times since owning this car from new. I do have a Shark ECU map and a Shark DSG map. I am in M mode, coming up to a traffic roundabout, as the traffic is not moving I do not manually change down gears as I know when I stop, the DSG will select the 1st or 2nd gear for me. Whilst slowing down the traffic starts to move so I am now rolling at say around 5 to 10 mph at this point. I press the pedal to 'go' and the DSG is effectively in neutral and all it does is rev up and I go nowhere cus it is not even in any gear at all! Now this is quite dangerous and indeed frightening should any car appear on the roundabout whilst I am 'stuck' in neutral frantically trying to get moving. Its so weird! If I do not select a gear in M then why is it not just staying in 3rd or 4th then? How and why it gets into neutral amazes me. I then find myself pulling the paddles trying to get it to sort it's sh*t out so i can get moving again. Anyone else had this before? Regards, Rich.
