I took both bulbs out and cleaned the terminals with a cotton bud, the side light display message never came back on, only other thing I know of is the relay may be faulty, there is one relay the controls all the lights, but is split inside in to various cones to direct and control the power outlet to each lighting system

Cheers

Gerry, which bulbs did you clean the connectors for side lights or angel eye lights?

AE lights...are side lights. The AEs come on when the light switch is turned from the off position to the 1st position to the right...thus if you have an AE burnt out you will get the side light out message.

Only mentioning this due to many past posts that say all side lights were checked...without specifically identifying the AEs, too.

Hello QSilver. Got a high regard for your knowledge and for your input. What is AE?

Thanks for the pic. I did a total walk around in every light position including hazards and all my lights work fine but continue to get the message. So I assume it's a bad sensor but don't know which socket to Clean?

It may not be over yet with checking the bulbs. I've been lucky so far and haven't had to do anything with my turn indicators...and these bi-xenon adaptive headlight assemblies on the facelift e53 are a lot different than the regular halogen & xenon lights on my other BMWs.

The LCM III (which we have) has a replacement light feature...which means that on the front and rear...if a bulb burns out...it can substitute another bulb by limiting voltage...or using the other filament in a dual filament bulb.

If this is the case...you may be looking at a bulb from outside of the vehicle...and it looks like the turn park lamps are okay when actually...the LCM may be turning on the turn indicator bulb (filament) and reducing its voltage so that it doesn't shine bright like the turn indicator. With these vehicles...you can't just look at the bulb from outside...you need to physically check each bulb...or do a test that will make a bulb that is been pressed into double duty...go crazy.

For instance...if a front park lamp is burnt out and the turn indicator is pressed into service...turn on the parking lights/headlights (which will get them to turn on)...but if you turn on the hazards or the turn indicators at the same time...the LCM can only illuminate one of those features...either the park light will go off or the bulb will blink for the hazards or turn indicator...it can't do both if one of the dual filaments is burnt out.

Again...you need to physically check the bulbs...not just look at them from the outside of the vehicle.

Thanks for the insight. Sound like a lot of trickery going on to keep bad lights seem like they are working. By doing it in the dark, can you tell which light is the culprit by the amount of illumination. Meaning, the light that's kicking in for the failed one looks dimmer?

The only way I know is to physically look at the bulb when its a dual filament. You can visually see that a filament is burnt or detached.

BTW, I jinxed myself last night. On the way home my CHECK SIDE LIGHTS warning came on. Got home and I have a burnt out AE.

I had the "Check Side Lights" message come on my X5 the other day. Before checking the forums I looked at the "side lights" on my car (the one behind the front wheels) and sure enough they were not on. After spending hours trying to get them to light up I searched the forums and read where "side lights" according to BMW are Angel Eye lights. Go figure. I looked at mine and sure enough one was not working. I switched bulbs and they both started working again and the message went away. Still puzzled why the lights on the side of my car (behind the front wheels) were not on, it dawned on me to try the turn signal and sure enough they flash to the beat of the turn signal. How frustrating but thanks to the internet for helping me track down the issue.

I was having the same issue and was sure what it was and I found this post and sure enough the angle eye light was out. Thanks

Mein Auto:
I've just started experiencing some concerning check light errors as well with my lights. I have a 2001 X5 4.4i with xenons, option S522A. I do not have the angel eye lights.

Last night, while driving I turned on my left turn signal and the "check side lights" message came on, the lights started flashing faster, and about 2 seconds later, the lights returned to blinking normally and the check side lights message went away. Then, just a bit later, while driving with my high beams on, I received a check high beam message. I didnt notice any difference in the light output, so i started to get concerned. So as I'm braking to pull over and check my lights, the check brake light comes on. Now i'm about to lose my ****. I stop the car, turn the low beams on, and test out each turn signal, with no issues present, hitting the brakes, checking to make sure no error messages pop up. Everything seems fine and checks out, so I get back in and get back on the road. Then it happens again. Random CHECK HIGH BEAM message pops up, then when turning CHECK SIDE LIGHTS. And it will randomly be fine, then just freak out again.

Not sure whats going on here, was wondering if i could get some input from people who have installed aftermarket headunits and are using the I-Bus app. I'm wondering if there is some coding issues between what the car was initially programmed for, and what the I-Bus app is trying to force into the coding.

I have been getting a check dude light error on my 04 x5 4.4 for the past three years. I was told the side light error is fir the low beam and could be a bad sensor or aftermarket bulb nit pulling the proper current. Despite the warning, all lights work fine. Your issue is a bit more erratic and most likely because of th3 aftermarket installation.

Why would the CHECK SIDE LAMP warnings come on if your low beam is out? The low beams have their own warning. (See list of check control warnings from the owners manual below that pertain to various light functions).

If your ďside lampĒ warning is illuminated...the first thing to check is ALL the lamps that illuminate (as stated early on in this thread) when you turn the light switch to the first position to the right of OFF. This will also include the small lights on the side of the vehicle that can illuminate when the turn indicators are used or the emergency flashers are initiated...and any other bulb that is on the side light circuit.

Can you name off what you consider the "side lights"? And have any of those lights been changed over from their original set-up to another type of lamp (ie like LED replacements)?

Again, the AE (angel eye) halo rings are part of the side light circuit and many owners in an attempt to make them "brighter" install LEDs. This could cause issues since the original AEs are not LEDs...so the circuit is looking for something with higher wattage. The lower powered LEDs can be interpreted as burnt out bulbs. The same goes for the turn indicators on the side of the vehicle...if they've been swapped over to LEDs...this could cause the check control warning.

If the dual filament parking lamps has one of the filaments burnt out...this could also cause the check control warning...and unless you physically check the bulb to make sure BOTH filaments are intact and not burnt out...the LCM will use the remaining filament to illuminate the parking lamps (this is part of the "replacement lighting" feature of the LCM III). So just doing an exterior visual inspection to see if the lamps are illuminated...can make you think all is well...but the warning persists because the bulb needs to be physically inspected to make sure both filaments are intact.

Oh now I see what is happening. Since these bulbs are not typically easy to get at, how can I tell which one is bad without looking at both sides. I donít believe leds where installed so it must be that one of my low beems are out. Thatís what I view as a side light, not the indicators on the side of my car when using my turn signals. Or could it be the culprit? What happened to the days when a bulb burned out you could easily tell which one It was lol
