Ошибка check side lights

Завожу утром машину, панель выдала «Check side light». Включаю все осветительные приборы по очереди, вроде всё горит, ан нет, когда габариты включаешь, в одной фаре горят кольца, в другой постоянно поворотник. Ищу в интернете что за дела, оказывается машина умная, если габарит перегорел, включает поворотник, чтобы сторона светилась. Вот шайтан) Еду в ближайший автомагазин, снимаю образец, у нас говорит одна только осталась. Ну ладно, давайте говорю одну, 10 ватт и в африке 10 ватт. Поставил, завожу ошибка исчезла, поворотник погас, колечко загорелось, ну и чудненько. Вечером когда стемнело, стало понятно, что лампочки всё таки лучше менять парой)

1. «Check Side Light» Message
   

   Having trouble tracking down a non-functioning light on my ’02 525i. A «CHECK SIDE LIGHT» error comes on the dash, and I see that the leftmost running light in the left headlamp unit is not working. The signal (blinker) filament works fine. I tried replacing the bulb, same result. I swapped the bulbs and bulb holders from left to right, same result. I tried checking for voltage on both sides, but it seems the LCM notes that its not hooked up to a bulb anymore, and I wasn’t even seeing voltage on the right side anymore until I hooked it back in. Thoughts?

2. The side light is the light on the SIDE of the fender, just forward of the front door.

3. And they are cheap and easy to replace. I was surprised how much dirt was on/in the old one. Definitely worth replacing both.

4. You’d like to think from the message that it was the signal in the fender. It was not. That one is working. The running light that should be illuminated when the running lights (first detent on the light switch) are on is not working. It is working on the right side. I thought I showed clearly in the two photos I provided which bulb was out, sorry if that wasn’t clear.

   My LCM does not warn when those go out. Is that a thing on more recent E39s? I thought those fender turn signals were «dumb».

6. Robert, I know what you told me on the phone, the running light being out, is it also the turn signal? The dash warning telling you about the side lights are not what you or anybody are thinking. That warning is letting you know that the little halogen bulb that lights up the angel eye rings is out. The fiber optic cables that split from the bulbs location splits up five ways. Two go to each angel eye, and one goes to the corner, that’s what lights up the two little holes at at corners. Check the bulb for the angel eye. The issue with the bulb that handles running light and turn signal, check the grounds.

7. Turn signals are all working fine. That’s the weird thing. It’s a two filament bulb.

   I waited until dusk to take some pictures. Actually noticed something I had not picked up on before. Anyway, here goes.

   First, car is running, lights off — just DRLs running:

   OK — let’s turn the parking (running) lights on — first detent:

   PXL_20230706_000456038.jpg

   I now notice a couple of things going on in this photo — the passenger side outer angel eye is out, and the orange parking light on the outer driver side is out. Before I had only noticed the left light out. Here are closeups, passenger side first:
   PXL_20230706_000500474.jpg

   And now the driver side:

   PXL_20230706_000504412.jpg

   Finally, main (high) beams on:

   PXL_20230706_000538626.jpg

   Here, it appears that the inner passenger side angel eye is out.

   Snotty rebuilt the units for me, and I recall we never wired in some of the angel eyes wiring. I’m not too worried about it, but I’m concerned that the warning light and the orange light out on the driver side could cause it to fail a safety inspection.

   So — where to now?

   A Ha! I think we have the source of the problem….

9. Pull the H/L assembly out of the mounting to expose all the bulbs.
   TIP: you will need a soft cloth to protect the top of the bumper.

   I am going to assume the lenses are facelift units as preface lift lenses look totally different. There is a parking lamb bulb in the far corner that aluminates the side part of the housing. I would also recommend replacing the Angle Eye bulb at the same time. Half of the connectors corrode so clean and add a touch of dielectric grease to the bulbs on install. Get a few

   KNOWN GOOD bulbs and replace one at a time.

   On the early preface lift models 97-99 you can use the turn signal wiring for power as they support parking lights and turn signal. On your model year the running change does not, so you need a tap to a «key on» power source for the angel eyes

   Oh and keep Snotty away from anything that is electrical.

    I can assure you that any electrical errors lie with me. You should see the wonders Snotty did in my wagon when a cracked taillight lens flooded out the compartment that had my amps in it.

    That said, it looks like the angels on the passenger side are out. I’d like to remedy that, but I don’t think the car will fail a safety over it. I’d like to figure out why the driver side outermost bulb is out (as a parking light). It works fine as a blinker.

    If you look at my original post you can see a photo of me holding the bulb outside of the housing, and the bulb is off. I had the parking lights on at that time, and the passenger side light was working. Since the bulb was out of the housing, I would assume that any dependencies on connections or grounds in the housing would be moot, as the passenger side bulb was running fine under the same circumstances.

    I’ll pull the unit out this weekend and go through the bulbs, housings and connections.

I’ve seen a ton of people replacing bulbs that are good because they don’t understand the LCM’s logic or haven’t read the manual.

    I don’t recall if US facelift E39s turn on both the halos and the amber turn signal at the same time for parking lights, or just the halos (in the rest of the world is just halos) so in addition to replacing your bad halo bulb you’ll probably need to look at how your LCM is programmed as it seems to be behaving as if coded for, say, Europe. Then you have the added complexity that you had facelift headlights installed on a pre-facelift car, which function differently. Wanna do a little experiment? Pull out the halo bulb that’s working and see what the car does.

    In short, you’re overcomplicating yourself when you probably only have a bad halo bulb and maybe an LCM that needs to be properly coded to handle US facelift headlights. That’s it. Your turn signal bulbs are likely just fine.

12. Eric you magnificent bastard! I looked into what you suggested, and you were exactly correct. The halo light on the passenger side was out. As soon as I replaced it, the parking light that had turned itself on to compensate turned itself off, and the error cleared. Thank you for explaining how the system worked, I had no idea.

13. I’ve been called many things, and bastard is n… Come to think of it, it’s something I get called often.

    So glad that was it, man. E39s are smarter than they look.

15. So….. I just got over a high fever of 103.8 degrees and saw this discumboobulation of the lack of following Snotty’s (ME) input. And Stephen, the two lit up LED like dots on the corner are fed via fiber optic from the same angel eye halogen bulb, why BMW calls it the side marker, or side corner light, I don’t know, maybe…… uh… that idiot Chris Bangle? <<< Best stupid answer I can think about.

16. I know you give the guy tips and tricks and he gives the solution credit to the Resident Third World Advisor. I am deleting Ratel from my Christmas card list.

    On the module controlling optional lights to keep one side illuminated was news to me but it does make sense that some safety engineer thought that would be prudent. Good post!

17. These cars were packed with all kinds of neat tech back in it’s day, pretty sure Bangle wasn’t invited to any of those planning meetings. They also have the capability of setting on a parking light on either side of the car in case you had to be parked on the side of a road.
