Mike,
I have read more on this and there is a software fix.
It only happens on the 1.5 130 DSG and is related to the coasting function. There is a second battery in your car under the passenger seat, not on other models. This battery assists with the electrics of the car when coasting and if this battery is a little low on charge or under big demand the error message will come on.
Keep safe and it will be fixed on the 12th December and in the meantime don’t worry.
