LED DRL turned yellow?
Noticed today that the inner DRL on the left (LHD driver's side) headlight has gone yellow. I'm assuming that the LED module for that DRL has gone bad and needs replacement?

Looks like it's not even illuminated but only reflecting the surrounding area lighting. Going to keep an eye on these on my car but I usually turn DRL's off anyways.

The part alone is around $1300. And these are the Xenon adaptive lights. Not even the newer LEDs. |

It’s definitely on. Just super warm and dim. I’m pretty certain some SMD LEDs or the driver has failed. Luckily, I’m still under CPO warranty, so I’ll just take it in. Looks like you can replace the DRL module which contains the driver and SMDs separately without replacing the whole headlight.

Why. DRLs are a safety measure that lets other drivers see your car. They don't affect the way you drive so why do you turn them off? |

Is your DRL turns white when you turn on the low beams? Mines goes back to normal white color when low beams turned on. They are only yellow on the dimmed (DRL) setting.

It is a known issue. In the US at least BMW NA has a TSB (Tech. Service Bulletin) on this issue and how dealerships are to fix it. They note the whole headlight doesn't need to be replaced, but a part does that causes this.

But if it only requires the module change, and if they stick with the 70% offer, it should not hurt too much. Good luck. |

Since warranty ended I accept to pay for the module. It's a reasonable solution for the problem. But replacing the whole headlight is a engineering failure at the design step. I'm just glad that BMW engineers didn't made such a mistake at design.

I had the same issue, they tried to replace the module only and it didn't work, they ended up replacing the entire lamp. Under warranty at this point...

I suspect this could be Over The Air upgrade to M5 CS style LEDs...
