Weird behavior of auto headlight

Alchemis · 10-22-2023, 07:08 PM

Hi guys,

I have a 2016 m4 right hand drive with led lights.
I realize when I put on to auto mode, one of the led light will no switch on when driving.
It's on only when on reverse or manually switch on the headlights.
The picture attached I circled in yellow.

He needed to add more stickers on that side.

Since the light emitting diodes do sometimes work, I would expect it to be a module causing the issue. They are cheaper than a whole housing, I would start there. But also, does it change with moving the steering wheel? Could just be the cornering led.

it wasn't an issue, it's found out that once the speed goes up 40kmh, the other side lit up properly.

Yeah that definitely doesn't sound like an issue...
