Just an update to this. The software changes worked, but I have noticed a couple of things in the subsequent months:Just had my UK Golf software updated. My issues were ACC slowing me down as it thought I was undertaking (when I was actually overtaking), incorrect speed display (110, 90 etc) and lights reverting to driving on the right.
I booked it in myself, and referenced TPI 2063230/3 and the fact that this included software version 1890.
They seem to have applied 1890 ok.
Tomorrow I find out if it has worked !
The dealer was Inchcape at Telford.

I occasionally get the false undertaking issue - perhaps once a month i.e. every 1,000 miles.
I still get the false "you are about to hit the car in front" alerts on the dash, but these seem more frequent - always explainable though from what is happening in front of me.
I do get occasional instances where the car slows down and applies the brakes, but there is no obvious reason for this, and there is no dash display message. This always happens in urban environments when other parked cars are around. I would expect some sort of dashboard explanation.
