LED DRL Yellowing?

Lately I've been noticing on my driver's side headlight that the outer DRL has a more yellow color to it on the left half when looking at the light.

Has anyone else experienced this? Is it something to do with the diode itself or the DRL module? Any advice would be appreciated



Thanks!

I can see what your saying the color temp is different say from 5000k down to 3500k , Never noticed it on mine , but I never really examined it , I will check it out to see.
I have my car coded Via Carly mod I think I bumped up the brightness on my DRLs , Iím not sure if that can help your problem , maybe pull the negative off your battery for 10mins to help reset the modules , donít forget if you pull the neg off the batt you will have to reset the time manually to get it back to normal the on screen computer will let you know

Thanks for the reply -- would disconnecting the negative terminal reset all of the modules within the car? I ask because I've coded various items via BimmerCode in Expert Mode and don't want them to all reset back to the factory settings. I'm almost wondering if popping the headlight out and disconnecting it that way would do the same trick? Understanding that it may take more time to do that method, but would save me the headache of trying to remember what I coded and how to get there.

On the DRL brightness note, I would like to bump them up but for some reason when I try to access the 'Front Light Electronics Right' module, it's unable to read the module whereas the 'Front Light Electronics Left' module is read just fine. Because I can't adjust the right side module to match the adjustable left side, I've left it how it is. If you have any insight as to why this may be happening, I would appreciate that also.

Let me know if you find out anything on your car. I'm sure the DRL's are the same across pre-LCI and LCI cars

Bump to see if anyone else has some advice

Car will be in getting a front respray and XPEL film in 2 weeks so the headlights will be most accessible with the front bumper and hood and fenders already off. I'd like to take advantage of this time to troubleshoot this issue.

I'm thinking that the problem lies within the DRL module in the headlight, whether its as simple as re-seating the connector (doubtful) or putting in a new module (~$125). If a new module is put in, does it need to go to BMW to be coded to the car or is it plug and play?

Any help or guidance is appreciated!

I'm not 100% sure but from my experience LED's tend to change colors prior to dying out. I've had this issue on 3 of my Mercedes S550 door handles which coincidently wasn't covered under their CPO warranty... I would sent Vito a message from ZWorks to see if he has any prior experience with this.
