So fuse 8 control the ambient lighting amongst other things but those others still work. Ambient lights  Was working fine then suddenly went off while driving tonight, dash and door cards. Checked carista but nothing.

Could be something simple like it's forgotten your driver profile. Had similar and it turned out the car had switched to guest profile with no lighting. just turned them back on in the infotainment menu. Start there before taking anything apart

Have you checked the settings in background settings havent been turned off?

Settings are on and profile is still set as mine

Is it everything on the doors? Stripes and pocket lights? What about the footwells?

All strips on dash & doors, footwell light ok and interior handle lights ok.
