Quite a few threads on this, but still stumped!
2017 Highline 150 DSG
Just fitted THQ rear LEDs - all good apart from the rear fog light, which worked prior. Refitted originals they no longer work either.
1. Checked all fuses in the central fuse - all seem to have 12v on either side when appropriate (ign on or off)
2. No rear light warning on dash, unlike the front fogs, but the rear fog light on the light switch is 'on' when selected.
3. Plugged in VCDS - went the convenience module and did an output test on the lights, everything works including the rear fog.
4. No bulb out warnings
It has a tow bar, but it's one that's connected to the canbus and that all works, apart from ..... the rear fog light since the above. I'm used to seeing the 69 towbar electrics not available.
MOT's a way off but I'd really like to get this resolved
Any help gratefully received before I find a better sparky than me
