Our 2016 VW T6 van has the rear offside brake light not working, light filament part works, just the actual brake filament not working. So go to change the bulb, weirdly filament looks ok in existing ‘not working’ one, but stick a new correct bulb in anyway but still doesn’t work. All the connections look fine. Why would it not work, anything to check elsewhere? Just odd it’s one side if not the bulb itself.
The van is still under warranty but it’s just a bit of a trek to take over to nearest dealer and lose work time but I’ll give the dealer a call maybe tomorrow and see if any technician there knows too before having to make a trip, but thought I’d just ask here before for any top tips. Cheers
edit, will try a meter on it later with mate to see if power is reaching the connections when brake pressed
