I had a very interesting hour at HazzyDayz this afternoon. The reason for the visit was to install the coding to activate TSR. It turned out that it is blocked by Skoda, currently will not sell the unblock code. Then tech guy then did a full scan of my 2023 spec Sportline to find out what could be activated. 
 Adaptive Cruise control replacement stalk and coding read.

Blind spot detection.

The most interesting was replacing the low view reversing camera with the high view and the additional read and front sensors to allow for park assist and trailer assist plus side view.

I’m finding that TSR fall well short of what I expected, the only signs it recognises are the Speed Limit ones - I occasionally get a warning in the Superb about a bend or roundabout but these come from the mapping / guidance software, not the TSR - even then it’s not consistent.
