Dlr not working

[magnumpk30]

Hi all
New to the group . I have a vw t6 18 plate highline with led day running lights . They don't work in the day on auto setting but do work if put them on to side lights .. on a night when the light switch is in auto the lights work perfectly. So it's just the dlrs are not working in the day as they should on auto ? Any ideas or solutions?

It does sound like the drl’s aren’t working and what you are seeing is the side lights or dipped beam headlights.
You say they are LED. Are they the factory LED headlights or just LED bulbs in H4s or H7s?

No lights at all on in day as in pic .. I will turn lights on to side lights and show . These are normally drls - the bottom strip

As they use the same LEDs when on side lights as DRL, you know the leds are OK...have they ever worked in your ownership of the vehicle?

Silly question, but have you tried with your handbrake off? there is a VCDS setting that turns off the DRLs when the handbrake is on.

Hi yes they did work until recently. They also don't work with handbrake off as I noticed in the reflection in mirrored glass buildings when driving. Many thanks
