Hi have a problem with dimmed headlights not working on my BMW 5 series 2012 model, will it fail a MOT test?

You can get it out from the flap in front of the wheel where is the acess to bulb H7 low beam,thats how i changed mine just push the plastic edge and get a better to angle to the far screw.

might be too late to comment but my passenger side light steamed up then the drls on that side stopped working and full beam on both sides stopped working. I removed the board which had white powder on it and cleaned it. i replaced it and still nothing. i then swapped the board from the drivers side and still no drls but the driver side worked with the passenger side board installed. I then removed the metal side ballast and swapped them around and still no drl. I have indicator both sides, dipped beam both sides but no full beam or flashing any side and still no drl on passenger side. I'm going to try and test the drl bulbs as you've shown tomorrow but have you any other suggestions please.

Hey mine has same fault and ive no parking halo on my left ,im ordering a tms module.. Can theis also cause battery drain warning on my i drive ? Kind regards Concerned BMW customer

Update, I removed the clear plastic lens cover and completely stripped out the headlight workings. I removed everything including the internal harness and found the problem. In a previous attempt to dry the light I placed a hot air gun in the top hole of the light and it was drying nicely, I then left it running for 2 minutes sat in the hole to get a screwdriver for my shed and, when I returned, the hot air gun had melted down into the light. This then melted several of the tiny harness wires and bridges some of them. I was able to carefully separate them and then solder in new cables. To be honest, it was fidgety but easy enough with patience. I then plugged all lights back into the main harness without re-building the light and everything worked perfectly. I've learned some things from this experience, namely:- 1. If you find moisture in your lights deal with it ASAP (I left mine too long which made things worse). 2. DO NOT USE a hot air gun because they are simply too hot, use a hairdryer instead but DO NOT leave any heat source unattended. My problem was self inflicted due to the melting. 3. Don't be afraid to remove the bumper it's actually not that difficult. 4. You can each some of the components from the wheel arch to check the main electrical board so check that first to see if there are signs of corrosion and steel wool them to try that first then, if that works, remove the light, dry it and re-seal it. 5. Removing the clear lens cover is very difficult so take your time and don't be afraid to cut off some tabs to make it easier because, once re-sealed it will be just fine. 6. I'm not sure whether this is right or wrong but, in my case, I drilled 2 small holes directly below the main electrical board in both headlights and covered them with fine aluminium mesh to prevent insects getting in. My theory is that the most delicate, sensitive part of the light (the electrics) is placed at the lowest point of the headlight body so the slightest bit of condensation will gather there so, by letting it escape I hope to increase ventilation and stop moisture build up. I've "accidentally" exceeded 80MPH in rain and so far the lights have remained dry with no water getting into the bottom holes. And finally, make good use of youtubers experience and follow them carefully because, if it hadn't been for this video, I would not have been able to repair my headlight. Its been nearly a month now of use in our crazy Scottish weather, torrential rain one minute and hot sun the next and my light is still fog free so lets hope it stays that way. Thanks again Tutoriale for saving me in excess of £786 for one light here in the UK.

Hi dear, left side day light some times working and rest of days not working with dashboard error massage. I exchanged the module to other side, I discover it’s working on the other side but still the left side rings doesn’t work. Where is the fault please

If the module is not original, does it work properly? Because one module is not original and in the evening the beam of that lamp runs in different directions.

There is an access panel in the wheel well, you don’t have to remove the bumper or the headlight assembly.

Great video

This is seriously insane for some damn lights.

I have errors ( side daytime light fault) and the (vertical aim error) the halos are working just seams to be the daytime small bulb in the centre that's not working on both sides. Will this be the module problem? 520d f10 2012

Hi Mine doesn’t work too and there is lots of condensation in headlights? So do you think I should change the module? Normal lights are working just the angel ligts gone???

Hi, great video. Is the indicator also part of this module? My angel eyes and indicator light failed at the same time.

I have a f10 525d 2010 with headlight vertical aim, Angel eye and indicator fault on both headlights. Wanted to know if they are same for Left and Right??

Thanks for the video. You have shown the easy labor part of the job. With some patience I did it without any tutorial anyways. The hard part is the coding/initialization. I am still researching how to do that. Please point me at the right direction if you know one.

Still waiting for the "Here's how to clean an extremely dirty engine compartment" video...

You don't need to have the module programmed by the dealer? Will it work right after replacing it.?

I'm constantly amazed by the lack of technical knowledge of these KZfaq DIY video-posters! I don't imagine there's anybody out there that is interested in changing a TMS Module in less time than the length of this video?? You really don't have to strip half the car to change these modules!! Also note that the module has a unique part number relative to the car model & headlight functions supported. Seek informed advice before buying the module & be aware that most all AHL (Adaptive Head Light) modules are NOT plug & play! There's likely to be coding required, so not really a job for Mr Joe Average?

Does new tms needs to be coded?

I had severe moisture in headlight and now have intermittent error messages for left signal, headlight aiming and angel lights. I sealed the headlight. Now it is just angel eye failure. Does the TMS corrosion impact all of these? Thank you.

I've changed TMS board and I have to as Its not fully functional I have halo rings don't have led top strip and vertical aim error code that's why I need coding thanks for quick response btw

For me the problem appeared after a carwash - the blinker and the daylight rings were gone on the left side. I was able to pull off the TMS module from under the wheel cover, without removing the bumper. For me it was just plug & play, no initialisation via ISTA+ needed.

Ken hell... I just turned my wheel undone the flap and 2 screws holding it in and done!!! Takes me 5 minutes.. if that..🤦

You don't have to remove the front. If you do it careful you can change it from the same place where you change the headlight lamp. Have done that a couple of times.

That access panel is poorly designed. It allows water to get to the back of the headlight. I had condensation inside the headlight, I put gasket silicon onto both the headlight access round panels. When I put the wheel well panel back on, I put clear bathroom silicon on the panel before I put it back on to keep water from getting in. I have not had an issue since.

That's a lot of unnecessary work... Changed mine in 20min from flap under the wheel arch lock your wheels outward on the side you're changing access module via flap

You dont have to remove anything. You can access the module in the wheel well. There is a flap. 2 phillips head screws removes the flap then 2 t20 screws to remove the module. There are videos on youtube that show you how. Its pretty simple. You Dont remove any other shit.

👏👏👏👏

Makes car die ?

In this other video kzfaq.info/get/bejne/ebifqdmd39nKo4U.html this guy found a way to replace it (Headlight TMS Module for F10) in . . . literally 3 minutes 😂😂 Almost No stripping of bumpers and dozens of plastic clips. INFORMATION (and OTHER people's previous efforts!!) is EVERYTHING 🥰🥰

No need to take off headlight

Brev dont remove the whole bumper
