Reported fix
I replaced with the new light switch and problem gone.

Reported cause
I had a similar problem with mine and it was the headlight switch.

Have 2 new bulbs and have the same problem before and after I changed the bulbs.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Went out to drive my car this evening and noticed both headlights are out. All of the other lights work fine, and the two headlight fuses are OK. I searched but found no cases like this.
Any ideas??

Oh, I forgot to tell you what the prize is...... since you won, you get to post a pic of your car in this thread.
If you post the pic, you might actually get your choice of a free mod! I'll be watching....
Anybody have the part number for the light switch handy?
Almost forgot, whats a post without a pictures??
This is after i installed the Eibach/Bilstein suspension two weeks ago, and the silver dash strips
Actually I didnt even read that far into honestly. If you ever look at the back of the light switch, it kinda looks like a birth control pack once you pull off the loom..........
I'm having a similar problem. The last 2 times I turned mine on, you get a bright flicker for awhile out of both lights and then they eventualy came on. They may have come on because I was turning the switch on and off and turned on the fog lights to try every combination. Is there a test for the switch or just bite the bullet and replace it?

Would you kindly post the schematic of the head light switch?
I am trying to see how it connects to the background display light (RPM, Temp, Analog Speedometer,
oil, etc)
My digital speedometer is always fine, but sometimes I am left in the dark with no dashboard light.
My headlights work fine.
The reason i want to see, is because the mechanic says the problem is the cluster model,
and not the headlight switch.
What do you think?
Thanks
The manual says to disconnect the battery before removing the headlight switch. I that really necessary? I guess other than having to re-input the radio code it's no big deal but not sure what damage I could cause if I leave the battery connected.
Went to have the car inspected today and both of my xenons are not working either. The high beams flash, the rest of the lights in the car work. The shop won't have time to look into it until Monday, hoping it's just the switch!
Are most the problems with higher amperage bulbs? If so I'd suspect arcing causing burn marks on contacts that makes passing current a problem. Even relays take damage if they aren't up to covering amperages of higher power lights.
Could be enviromental where the acid rain of europe keeps the switch cleaned
Cool dog. Love that pup as much as you can. I miss my golden retriever dearly. Excellent dogs for posing and being friends. Super chow hounds for sure.
My switch went, too. It's, actually, a pretty dangerous little failure to have when you live out in the boonies and there's a deer around every corner.
Sorry to revive an old thread. Did all of your headlight switches fail with both lights at the same time? I am having intermittent failure of the left light to turn on.
