Hey everyone. The other day my xenon went out on the driver side. Didn't think much of it. Purchased a new set of DS1 bulbs. After installation headlight still out. Checked the fuses, fuses are good. Starting looking closer, no high beam either. Read the codes and came up with the following:

A8B0 Direction indicator
A8AC Clearance light
A8A8 High beam/turn-off light
9CBF Communication with step motor disrupted
A8AA Dipped beam

So I am thinking it somewhere in the wiring.

Can anyone give me some guidance thats had a similar issue? It's an 07 E90 N52.

Thanks!

Anyone?

I'm not too sure but the same thing happened to me a bit ago, I replaced the bulb it was still out and decided to buy a ballast, replaced the ballast and all was good, but now my headlight sometimes turns off and I don't know what's wrong (after a few months of changing ballast) so I might get another ballast. I don't know about the codes tho since I never checked up on them. Hope I was able to help.

Thank you for the input. Hoping for someone to chime in with same issue, don't want to start replacing parts just yet until I have a better idea.

Well now my right xenon is out and doesn't seem to be turning on in the near future I don't know whether I am going to change my headlight unit, make them led, or just replace the ballast again. Ill talk to this guy i know and let you know what I end up doing probably over the weekend.

Thanks!

you have problem with positive wiring from FRM or with ground (negative), which is connected to body near headlight, on the fender carrier

[Lucid Moment]

Thank you, I thought I had an issue with wiring based on my search. Recommended fix, removed headlight to gain access and start looking at any exposed wires, or damaged?

I finally got around to working on this issue, got the headlight off, looked inside, no exposed wires or connections. Traced the harness, nothing unusual thus far.

Should I go ahead and pull the cover for the FRM module and check wiring there?
Any areas that I might check?

Any other suggestions are welcome.

Thanks everyone.

here is pic on my car

you can see 5 or 6 brown wires attached to body using ground plate
all wires to headlight coming from two source - all positive from FRM in drivers side legroom
all negative from ground plate near headlight
so we can see that FRM is working, windows open, door lock too, other headlight works, rear lights too
so we have to check ground connection
if it's good than some headlight drivers in FRM gone due some problem.
frm have internal short-ciruit diagnosis and wll disable faulty circuit and show fault code about it, you don't have it

You have the last 7 of the vin. I want to check the wiring but I know the SMC on the right side is the slave I think I get them backwards but I would like to see the wiring diagram see if we can narrow a place to look.

So neither headlight works ? What lights are working right now

May be the ballast is out, not the bulb...

Ah, finally , I had my moment today. Struggled with getting high beams to work after new ballast install. Did the splice fix on connector to ballast and got hibeam on driver side.

Today after messing about with this for ages , I gave up, ending up in finding the reason for no hibeam on passenger side, broken wire, the #5 in socket needs give positive or no function of shutter. Fixed and now all good.

Always check your wires hahaha , feel stupid, I must admit that , but I dont care , I have hibeams again

OP did you ever resolve this? i have the same issue after replacing bulb and ballast and checking fuses
