I had the same kph fault, car software was updated to version 1803. Still have the kph issue but the satnav is smother.
Did yours do the driving on the wrong side of the road thing?
BTW from talking to friends at the weekend, traffic sign recognition seems to be a problem all over the place.... BMW, Jaguar, Polestar, Toyota.
I was talking to my friends at a meet up about my Mk8 woes and all of them have all sorts of similar issues with their new cars as well.... sometimes we can be a little tunnel visioned about this stuff.
Possibly suggests some of the components that do this are off the shelf components (well, actually, I know they are) and the fault is with Bosche or whoever...
