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.
Just noticed something else. Previously I had “Device part number“ 5H0035820F. I now appear to 5H0035820H.
I guess that means I have new hardware too i.e. a new infotainment unit.
