Headlight Washer - Inquiry

[DBACE]

I have typically thought of this system as a bit gimmicky. I have never seen the headlight washer in action for obvious reasons. The owners manual says pulling the windshield washer stalk back towards you the windshield gets cleaned and in addition at regular intervals the headlights are cleaned. I read on an F80/F82/F83 post in the general section that it activates every third or fourth time the stalk is pulled back, but the lights need to be turned on.

I found a video that shows an older BMW system being activated:

I think I will have one of my Boyz video to record the system at work on my F80.

I am curious to learn if the nozzle(s) are heated like for the windshield? Has anyone videoed a current F80/F82/F83 system working? Does the washer fluid articulate across the lens or, as in the above video, are there two primary jets that just hit the center of each light in the housing? Does the system work, only in Dynamic Mode, when the lights are turned on by darkness and when turned on, in non-dynamic mode?

The location of the unit, is offset quite a bit from the center of the light. Why is that?

I guess BMW thought that those washers are not the greatest idea, and 2018 F80 no longer have Headlight washers..

The reason is the 2018 has LED only. Older models coming also with Xenon which requires the washers at least in Germany.

Ahh. So that is why no headlight washers on 2018 M3s... I was wondering.

Interesting.

Also interesting. I am curious how a Xenon vs LED would matter with the housing, being pretty much the same, in regards to needing a cleaning. Do Xenon lights cook the dirt on?

I went Auto-crossing this weekend, and before each event I inspect the car, ending in a bath. I had my son use his iPod and he captured the washers in action. Man, do they use up some washer fluid. Two nozzles hit each light center as I thought it might. Quite a bit of the washer fluid splashes onto the hood. It looked like the car was profusely crying after it was all said and done. I will post the video later today.

Washers are required in Germany for any light on a car with lumen higher than 2000. Xenon is around 3000 lumen, LED is below 2000 lumen.

Xenon with dirty glasses could blend other drivers.

Wait a minute, so LEDs output less light than Xenons?

In theory LEDs should require more cleaning in snowy weather since they don't get hot enough to melt the snow. Maybe they tweaked coding or added some heaters in headlight to turn them on during winter

Anyway, I found a F30 headlight washers in action, it should be the same thing as in F80. It seems to spray with good pressure. I wonder if both sides spray at the same time or they take turns

Interesting that the 2018 models don't have the washer. I wonder if there is a manual way to by-pass the intervals to test/wash the headlights?

Do you know why? Not that I'm missing them.

Canadian f8x models don't have them either. I believe this has been the case for the entire generation.

I was wondering the same with my 2018. Wondered why there was none but 2017 had it. Now it make sense.

[ArieArie]

I think it has to do with the switch to all LED headlights.
My guess: LED headlight do not heat up as much as the HID and the dirt/salt doesn't dry up as fast and doesn't accumulate as much. maybe?

Here I thought I had a leak in the windshield wiper hose, lol. Wasn't even aware I had these things.

Hi,
Can anyone please advise, where does this go?

Where does it hold to bumper? I removed old bumper and these felt down. I have to understand where to attach them to new bumper.

Thanks!

Just had this happen to me while taking the oil cooler pannel from underneath. Did you find out where is this mounted?
