Led interior lights not working

[Keneil09]

Hi all I have a q3 with the upgraded led pack. It gives you led interior lights. They have all stopped working including the roof, boot, glovebox vanity mirror. I have checked all the led bulbs and all are working. Can’t find a fuse for them anywhere . So am thinking they may have a relay somewhere but don’t know where to look. Any help would be most appreciated thanks

I'd definitely recommend a diagnostic check to see what fault codes flag up.
