Rear fog light not working?
My rear fog light is not working? Have checked bulb and all good. Front fogs work fine and get light on dash but nothing when pressing on the rear fog light? Any ideas?

Use a voltmeter or a test bulb on the wire to see if 12v is getting there in the first instance, if it is then check out the bulb holder for corrosion, clean and try again. If not then check out switch with voltmeter and/or test bulb to see if switch is working by connecting to the output side of the switch and seeing if it actually switches the voltage. Check the live side in the same manner to make sure its got power into the switch. If the switch is duff, replace, one of the breakers on here should be able to come up with one if you ask.

Colb thanks for that, will check it all out. I have a feeling it will be the light switch on the dash? I have read that just changing this will cause issues with mileage etc. is there a way to code this out? Cheers

Yes car info is stored on the switch unit so replacement would need coding to the car with its Vin number, NCS expert software should do it

Did you manage to get anywhere with this? It looks like I might have the same issue. I'm trying to find out which is the output from the switch unit so I can test.

Hi, it’s the light switch!!! Got the car in for MOT at a BMW specialists. Was told the switch’s are on back order globally and are approx £400!! They are trying to source a 2nd hand unit for me. Best of luck.

If you mean the LCM, I have one here. Just need to get it coded then.
Think mine is a double adjusting wheel one for halogen lights though?
Can check if it helps?
Oh and I think there are black or grey ones too.

Yeah, it’s the LCM. I have xenon’s on my car, does anyone know if you can use a halogen LCM with xenon’s? Hopefully the garage have sorted one?

Thank you all, I was really hoping for a cheap and easy MOT as I’m going to lose enough on the car anyway. Do you have a part number on you LCM? Mine is 6 936 810.
