I understand how this happens…

But why when it's so new?

Anyone know if something like this is covered under warranty?

[KJ10]

Is this a new m240? If so there is no reason any condensation should ever build up inside the headlight. Realistically it never should if it the headlight is in good undamaged condition. I would assume BMW would fix this for you.

Yeah it's a new one.

I've washed mine twice with a power washer and driven through a lot of rain. No condensation at all with mine. Definitely sounds like a faulty headlight housing or gasket somewhere

There a loads reporting this issue in the UK. Some have had multiple headlamp unit replacements done under warranty

That would be scheduled to be replaced as soon as I saw it. Damaged or faulty housing.

I have the same issue with mine 2022 220i September, I’ll report it and see what they say

[Nicolas05]

t’s a well know and documented problem with all G42’s.
Have my both headlights schedulded for replacement (under warranty) but they are backordered for now, no delivery date known.
They have been massively replaced, but even then apparently, for lots of people it didn’t solve the problem and it just came back even with the new headlights.

Yours look pretty ok even. Most have really thick droplets and watermarks.
This his how both of mine look.

Just contact your dealer, he should take care of it

[Dinosoar]

I had noticed slight condensation on my 230 also. I am glad to hear it is covered under warranty...not so happy about the wait time.

I had one of the earliest production G42s with a date of 10/21. I wonder if this is from the very beginning including recent cars produced in 2023 too???

UPDATE: So, my headlight got really bad, then improved, all the while the other one started up. That said, I talked to the dealer a few times, brought it in, sent pix and did a lot of research. This is just flat out common on a lot of BMWs. It is in conjunction with weather mainly. There plenty of models and model years where this happens. Lots of YT videos of guys using hairdryers to blow out the opened up headlight housing. It is quite sad this is so common. Not saying don't have BMW replace it, but you may continue to have the issue.

[marcsg42]

Haven’t seen mine do that yet but I’m sure it a matter of time but if if it makes any one feel better my cousin just bought a Tesla and has condensation in his tail lights

[N240i]

I'm actually also experiencing this issue. Brought it to the dealership and they told me they couldn't do anything about it because it wasn't happening in the moment (even though I had video and picture proof).
Was told to bring it in whenever the issue is present so that they can verify it in-house and make the warranty claim.

Good luck getting a new one. I hit a deer and my headlight is on backorder with no ETA since November...

Are they designed to be completely and permanently sealed? Or are there openings with gaskets for the bulbs and wiring? If the latter, it will keep happening unless you live in a really arid environment.

Glad someone seems to understand this.

The lights are not hermetically sealed. They have the weakest of plastic to plastic access covered to the bulbs. Moisture will always get in and thus condensate.

Regardless of the above , it’s f***inn annoying and not expected of a BMW.

That is the thing, nobody understands why it happens, even the dealers. So they will just keep replacing them and the problem just persists. I dont know why some platforms do it more than others. I assume it must be related to the shape of the housing or a lack in adequate ventilation in the design. I dont really know. But I definitely understand they are not sealed with a vacuum inside, so moisture is getting in no matter what. You want them sealed from direct liquid water intrusion, and if that is happening, then replacement can fix it. But if its just condensate from the air, replacing it would be a very temporary solution.

I think the key point is comparison with other BMW models both current and past. I've had several 3 and 4 series over the years and the headlights do steam up a bit from time to time but with just a thin film of condensation not droplets like we are seeing on the G42. We have a lot of rain in the UK (who knew eh? ) and I've never seen anything like this on any of my BMWs.

Rumour has it that BMW in the UK has admitted to some customers that it isn't right and so I'm hoping that message has got back to the mother ship in Germany and a rework is in the works, but, as ever, we'll have to see.

Must be humid all the time. That lower area of the headlamp is probably cool relative to right in front of the LED beam. You'd have to remove all the moist air and really seal it good.

[KJ10]

I am also unfortunately experiencing this now. I'll report back on what I am told by the service center.

[BMW2OWNER2022]

Confirmed today they are changing mine under warranty. I’ll keep you updated

[BMW2OWNER2022]

Headlamp on 2-3 week delivery so I’ll have to take back.

[g42bmw]

I'm also waiting for a headlight in the US. I have the shadowline version.

[John1973]

I've had both headlamps replaced under warranty. The passenger headlamp in the replacement now contains water. Will be calling dealer again re this to have it replaced
