Hey all,

I changed my stock pre lci angel eyes to to LED ones from MStyle about 4 months ago.
about a week ago the dash warning came on and i discovered that the drivers side angel eye light was not working. i had a look through today to see if it was the LED lights or the resistor, well the bulbs when swapped over on to the passenger side worked, so i gathered it was the resistor. However when i put a normal H8 bulb that too did not work :/ confused.

any ideas?

Thanks

Have you checked to see if the loom that connects to the back of the bulb is ok? (cable condition and pin condition?). Also might be worthwhile checking the big connector on that headlight to ensure that its pushed home correctly.

Either that or blown fuse:if resistor had failed maybe caused an amps spike and blown it.

[AnthonyR]

thanks for the replies guys....iv checked for all the connections, which are fine, also took out the fuse to see if its ok, which was fine too ... puzzled :/

Is the corresponding tail light working also?Could be worth pulling the battery for 30 mins to reset the footwell module.

just checked all the other lights and they are fine.
would disconnecting the battery cause any problems, like the remap and any coding, including the stereo pin?

[KM79]

Shouldn't be an issue only thing you'll have to do is reset the clock.All codings/maps are stored in the corresponding modules.

thanks, i may give it a go and see.

If the battery reset doesn't resolve it, it might be worth getting a multimeter on the connection pins to see if power is actually getting through. If it isn't it may point to faulty/damaged wiring within the light unit.

Gd luck with sorting this mate, hopefully see you soon...

Definitely try reset the footwell module by unplugging the battery first

[AnthonyR]

Thanks all, I will reset it and see how it goes
Yes josh hopefully there will b a local meet soon

[AnthonyR]

Hey all, I've reset the footwell module as instructed and still no joy. I think it's the wiring, but not sure how to sort it out, perhaps a trip to a garage might be needed

[KM79]

Get a multimeter,pull out the bulb and check across the two pins for voltage with the lights turned on.If none present then I suspect it could be an issue with the FRM.Its quite rare for a wiring issue for this type of fault.Also
Worth checking at the corresponding fuse for voltage also to determine a wiring issue.If there's voltage present there but not at bulb then indeed there must be an issue

+1
Use mutimeter and if there is no voltage or less voltage, you had a short circuit which made the FRM faulty.

FRM reset / or FRM change should do the job.

Thanks guys. How do you reset the FRM module or how much would a new one be?
Thanks

[KM79]

Not entirely sure how you can do it without diagnostic gear mate, I thought a power reset would do it.With BMW gear you can reset individual control units.I know some control units have counters in them for faults where as if a certain fault occurs repeatedly it shuts down a circuit or flags a warning light etc

[AnthonyR]

Thanks mate

[KM79]

No probs hope it's just something simple.Worst case scenario is FRM replacement plus programming.I can't recall how much they are but £180 springs to mind...!

[AnthonyR]

Ok thanks, I think I will get it checked and see what need be done

[bmwak]

If you have access to a multimeter it may be worth removing the big connector at the back of the headlight, turn the lights on and check for power going through the pins. If there is then that would rule out the FRM being faulty and point to the internal headlight loom (I say this because its happened to 1 Series I know but this was the headlight bulb, as opposed to the angel eye H8).

If it points to the FRM maybe look at getting a coder to write the module back to factory settings via the OBD before shelling out on a new FRM module.

[AnthonyR]

Ok makes sense, I need to get hold of a multimeter

FYI, different pins have different allocation for different bulbs.
OP's life would be a lot easier if he just check the terminals of the connector going to Halo rings.
More specific and more sensitive test IMHO.

+1 on checking it first before buying / replacing the FRM.

And just to correct, resetting the FRM back to stock would not help usually in such cases.
