Doesn’t this just mean that there’s a crack somewhere and it’ll come back? In addition to no sound, I replaced the front passenger light (it was off an M2 that had been sat outside in the winter cold and wet for 2 months before being put on my M235i) and it has this issue but in addition, there are big water droplets. I read in the manual some condensation is normal but this seems excessive. Wondering if it’ll go away/should have gone away as xenons do heat up. Thoughts?
I found it best to remove the cover and close the lid to be very effective with the engine running. In dry conditions you can drive like this as it gets more heat than from a hair dryer.
We have a 2011 BMW X5 that has ccondenstation in the rear brake lights both on the body and on the hatch back, to you have any tips on how to dry them out? Thanks!
Thanks for sharing your experience with clearing the headlights of moisture. I've same headlight units with top access, completely dry in about 20mins on medium hairdryer setting. Left access cover off for several hours to allow further venting as the headlight cooled down.👍
Contrary to popular belief, headlights are not air tight by design. Most even have vents designed to circulate air, but a headlight is not at all designed to be completely “air and moisture tight” Infact, sometimes the issue of a moisture build up is caused by a blockage of the ventilation, as if a headlight is properly vented, there should be no moisture that gets trapped.
I currently have one headlight, the driver side, that does not light up and was full of water droplets and condensation before they failed. I had my mechanic change the adaptive headlight module because the adaptive headlight didn’t work not too long ago. Is it safe to have the auto headlights on if one works and the other doesn’t? Or will I just fuck up my light even more? The angel eyes still works but the high and low beam don’t.
@@chrisl8873 I drilled a hole in the black casing,the condensation just needed a vent when winter came I plugged it with black tack,no trouble after a year
@@highlysuggestible861 I can’t see the benefit of using compressed air, because you’ll just be pushing the water to the bottom of the light where the ballast is.. And all the electrics will get wet.
@@carlubetv the air saves time on the hard to reach corners, air in a can with a small extension on the nozzle, clear as much of the lens as possible, then heat to dry.
I had condensation in my E39 headlamps. Following advice online, I drilled a small hole (3mm bit, I think) at the top of the lense, just under the bonnet, and they've been clear ever since !
Some suggest using gel superglue all around the headlight to stop if from leaking into the module. The blinker was flashing too fast and failed inspection.
I ave been work in moter trades for 77 years and no one parson now how to stop misting up in a head light ..thay no how to dry it out and that about it
I would like to retrofit the headlight cleaning system, can you please help me and tell me how the spray nozzles are attached? they are clipped in when I look at the nozzle, but I can't find the opposite where it comes in in the bmw catalogue. Could you give me the Part Number?
It depends what modification you go for its not just one, If you can find the video I did will explain how it works there are a variation of different explanations in there
@@carlubetv I mean, if you watch this video ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nTnI9cnUbZ0.html ) from 00:03 (where it's not real sound) and from 01:00 (when it is a real sound of an M3) you'll see the difference.
@@Supremepikachu This is really a physics problem. The fogginess/ condensation will continue just as it does with the windshield and even on your home windows. When there is a significant temperature change on one side of a nonporous surface compared to the other side, condensation will form on the surface. Just like when you take a cold can of soda out of the refrigerator. Automakers may have to start making defrosters/ dehumidifiers for headlights to correct this physics problem.
Hey CarLubeTv. Thanks for your video. Do you know how to resolve this issue on a E87? I don't have the access covers on the top like you have here but flaps at the back for bulb changes. barely big enough opening to fit the bulbs through. Many thanks.
Joseph U hi mate, your headlights still have a cover on the back of the unit, I would take those covers off and leave it for a couple of days to breathe, they should clear.
That works fine. The idea is to get air flowing removing the moisture (no liquid vater). I did that today, vacuum hose into one of the bulb holders and heat gun heating the outside of the lens. Took about half an hour to get all moisture out (it was heavy fogging with solid water droplets galore). I dont have any big lid access to the inside of the lights on my Mitsubishi ASX.
SPG 565, That is correct, A vacuum would be better. But the only problem is that a vacuum does not heat the air to turn the water into a gas/ steam. If you ever put your hand over the exhaust vent of a clothes dryer, you will notice the hot and moist air being blown/ sucked out. That is what you want to happen inside the headlight .
