Will be hard unless a UK one is breaking.
FYI, I have upgraded mine to the later unit with the larger central rev counter with no issues, mileage was also coded correctly. Every function works and all notifications and warning lights work with no issue. Only thing that is not present is AFS, but as I have the DRL lights that dont have AFS, there is no menu or errors. Later cars with the DRL don’t have AFS.Even fully checked via Techstream post fitting by Lexus and all confirmed working in spec and correct.
