Have a problem with my e90 335d.

Dipped beam works fine, and when full beam is put on the full beam symbol shows on the dash, however the xenon shutter doesn't raise, and the main beam bulbs don't light (same issue on both sides).

After checking it out, there is no power going through the main beam wires (cant remember of hand - think its into pin 5 for xenon shutter and pin6 for full bea,). The headlights are fine - as tested connecting a 12v supply directly to the pins. So obviously its losing its power before it reaches the headlight.

Anybody have any idea what it could be? Module of some sort??

Pin 5 in the headlights goes to pin 41 on the footwell module. Try connecting a wire to this pin and seeing if the shutters work. If they do then there could be a break in the original wire.

Brilliant, will try this at weekend. Does pin 41 operate both passenger and driver side headlights?
If it doesn't work is it likely to need the footwell module replaced?

Pin 41 is on the x14260 connector and operates both lights, my retrofit kit shows it as a brown wire with a yellow tracer but an original loom might have different colours.

Before condemning the footwell module I would try and recode it. Also check all the earth connections coming from the headlight.

Thanks for the help. All earth connections were check and even added a few new earths to make sure. Not really sure who can do the coding in the Northern Ireland, but Il try and find out.

Did your car come with xenons or were they retrofitted?

[gerdy]

As far as i know it came with the xenons. Any way to know for sure?

[makkan00]

check the last 7 digits on vin decoder. If it was OEM, then there will be xenons.
If it was fitted later, you will not find xenons there.

Lastly, if its pre-LCI xenon, then they use H7 as high beam and are not bi-xenon AFAIK.
If that is the case, it is worth of checking the fuse for high beam (if xenons are factory fitted).

Sorry dont understand - what you mean vin decoder?
It is pre-lci - When i connect the power directly I can see and hear the xenon shutter operating. So on main beam, H7 and a full view xenon should be on.
Can you get a 335d m sport with xenon headlights? Im yet to see one.
Where is the fuse for high beam? I had a fusing layout diagram for the box behind glovebox, but couldnt see any mention of a fuse for high beam?
And thanks for your help.

Gerdy is right.

Pre lci e90/1 xenons do have a xenon shutter and separate h7 high beam.

You can get any model with xenons Gerdy, just a tick box option, they were a pricey option circa £1000+ IIRC.

Good luck with repair..

Did xenons have to have headlamp washers?

[doughboy]

Always, it's a legal requirement.

[gerdy]

Anybody know where thr fuse is for main beam??

[bishbosh]

Sam, pre lci xenon are bixenon and do have a shutter, remember my xenon retrofit?

Gerdy, did you look at the fuse diagram behind the access panel in the glove box?

[gerdy]

After checking out im assuming my xenons have been retrofitted as theres is no self leveling sensors, and the light switch has the height adjustment on it.
Bishbosh, i checked all fuses in that panel and all were ok, but there didnt seem to be one for the headlights.
Any need to upgrade footwell module when retofitting xenons or any coding etc? Headlight full beam might never have work since fitting.

[bishbosh]

Yes the module should be coded. Did you look at the full thread on my link above?
Generally you ought to swap the footwell module for one that supports xenons, however I did manage to get my lights working and coded on my old module, I swapped it anyway for completeness sake.

It does sound like a retrofit that hasn't been done properly.
Question: do your inner halogen lamps light when pulling on the stalk for flash-to-pass?

Thanks guys. I just bought a pre-LCI car with xenon and when I pulled the stalk, H7 bulbs turned on. My impression was that they are not bi-xenon so time for me to have a look again.

As bishbosh said, you may have to run the wire for the shutter.

going back to my earlier reply, this is what I stated.
If 522 is not in your car description on bmw vin decoder, then you have retrofitted xenons.

Good luck with sorting it out.

Yes i think its a retrofit - the wire for the main headlight mean has been sliced into to allow another wire to operate the xenon shutter.
No the inner halogens (Or the xenon shutter - sliced into the same wire) doesn't work on full beam, or when pull the stalk towards you (flashing). Can coding be done remotely using team view or something?

To sort that you splice into the wire for the main beam (Pin 6), and run it to the pin operating the bi-xenon shutter (Pin 5) - (Pin 5 and 6 both into the wire for full beam- otherwise there must be an issue with the shutter itself.

Ok, just had a look at my car.
Oem method:
When I pull the stalk, H7 bulbs turn on and not the bi xenon shutter.
However when I push the stalk toward the front of the car, it turns on H7 and shutter is released so xenon is reaching further ahead.

Clever engineering.

On LCI xenons, they have bi-xenon and no H7s.
So either way the shutter is released.

[bishbosh]

I did my xenon retrofit with levelling sensors and coded it myself with a few pointers from makkan.

They now work in the same way as factory xenons.

When I pull the stalk the inner H7 halogen lights up (for flash to pass).
When I push the stalk with the lights on the shutter flips up for main beam.

Gerdy, you might want to check that your footwell module has been coded properly.
