I recently bought one of my dream cars couple of weeks ago, a 2020 M2C with 7200 miles for a decent price. The car itself is great so far, wonderful power with great looks. The only issue I'm seeing is that the driver side DRL is quite a bit dimmer versus the passenger side, which I recently noticed when seeing my lights reflection off the backside of a car.

Do I need to get a new headlight? I tried asking the local BMW dealership whether this is covered under warranty, but was told that it was only covered if it's broken, not dimming…

That looks "broken" to me

The dealer is full of ish, the headlight/module is covered under the factory warranty (also extended warranty for the module). I would try another dealer or push the issue with the resistant one.

However, if you want to repair it yourself, you don't need a complete new headlight, the DRL LED module is sold separately and takes 5 mins to replace.

Part number: 63117494851

Awesome. Thanks for the quick response! Just found YouTube video of a guy having the same exact issue as me and that replacing this module fixed it for him. Hopefully it works for me too…went ahead and ordered the part.

But why not use the warranty to get this fixed? Unless you're paranoid the dealer will screw something up.

Absolutely get that fixed under warranty!! NFW that should cost you out-of-pocket. SA at the dealership was an idiot.

My local dealership is like 60 miles away. The part was only $150 with shipping. I rather pay out of pocket and seems like a very easy install than deal with the inconvenience.

So…I got the LED module and installed it, same issue. The driver side DRLs were still relatively dimmer than the passenger side. Digging around, it seems the issue all along was the DRL lens that guides the light from the module was not properly installed in the module housing… Well, at least I have an extra DRL module for later on.

Sorry to hear the module was not the issue with your DRL but I'm not sure how the rings came out of place, maybe a physical collision shifted them within the headlight housing because there is no mechanical parts within the rings to go bad, it just simply magnifies the LEDs lights from the module. Although they might look complicated from outside, it's a pretty simple MO and easy to diagnose..

You can sell back the LED module, they move quickly on eBay..

How did you manage to solve this? I’m having the same issue and changed the module but that didn’t fix it
Thanks

I'm having the same issue. Same halo as well. Does anyone know if there is a way to test if it's the module or not, without buying a new one and installing it?

[jstnf87]

Is there any tutorial on how to adjust the DRL rings and put them back into place? Have the same issue with my 2020 example. Just today I noticed my driver side inner DRL halo is a tad dimmer than usual.

[Stealth.Motorwerks]

I'm having same issue on mine. Same inner DRL on the drivers side. Is this a common issue?

[Stealth.Motorwerks]

So I opened up my drivers side headlight underneath the DRL Module and the clear tube that shines the light from the LED to the halo rings was broken. Any idea if or where I might be able to find a replacement for that part?

As I understand it, the front headlamp assembly is pretty much sold as a packaged unit. I don’t see the halo light guide listed as a separate component on RealOEM:

I have the same issue but mine is one on the passages side inner halo. It’s also dimmer and same problem after replacing a new module. Keep my eye on this post👀👀👀, hope someone find a solution and share

[Discreet_335i]

I have a similar issue on my passenger side inner. Module is working correctly but the inner is significantly dimmer than the outer.

[Track/S]

Mine has changed color...

[tenaciousd]

For the changing color that is most likely the LED module going bad. Replace the part referenced in post #3.

[Stealth.Motorwerks]

Having the same problem. Opened up the headlight module and have a broken tube as well. Is there any way to successfully repair this or replace it with a new tube? Haven’t been able to find anything besides this thread.

Changing entire headlight.

The tube is part of the eye:

I have a passenger side headlight in 98% condition if someone is interested. Hope I don't have this issue in the future!!
