Interior light not coming on

[Dazzncl]

Hi everyone this is my first post, have a problem if anyone could shed a light on, just picked up my T6.1 and the interior lights come on ok when unlock van and come on when open side door but won’t come on when open rear barn doors, I’ve tried everything but no luck, not sure what to do now

It should be coded for this from factory but from memory there are specific coding options on the BCM for this. However, this is T6 BCM coding, the T6.1 BCM is a different beast.

Have you checked the infotainment vehicle options to see if there is an option for this there?
