Damn I never replied …
So to catch it up, the issue was the bulb holders/cluster arrangement had an issue which melted the plug and somehow took the REM module with it. So even with the plug repaired and a new board/cluster still nothing.
so REM fitted and some pain getting it coded (I really wanna know how to do stuff like that) all was working and all the things that stopped working because of the used REM now work again.
and then very recently I’ve ditched the rear lights swapped to LCI rears, wired and coded etc. just front head lights to swap now.
also fitted some new front grilles which I’m particularly impressed with.
