2018 Vauxhall Vivaro only 1 drl working when side lights turned on no side light and no daytime running lights

Try swapping the drl bulb / led with the one that's working or test and see what shows .

Hi I tried that and still nothing

Have you tested for power at faulty DRL ?, might need scanning with Tech 3 or similar

No power at bulb, agreed scan tool next, was hoping to figure it out before calling in an Auto tech

Thought it may be a fuse related fault but you have checked them
