Anyone get their rear fog lights working? We do a lot of driving in rual areas that aren't lit and I really want to get the rear foglights working. On my X5 it was a new switch and one wire to the FRM module, but has anyone figured it out for the F48 yet?

[KPD]

Headlights or front fog lights have to be switched on for the rear fog lights to work. I've used mine a couple of times so far without any issues. Used it just last night in fact.

Yes, but in North America, our light switch only has the button for the front fogs. On some models, like the E90, it was just buying the right switch to get the rear fogs to work. On other models like my E70, you had to run an additional wire from the light switch to the module which controls the lighting.

I don't know where to find the F48 wiring diagram (my copy of WDS is too old), so I can't see if there are any differences between the Euro/Aussie versions of the car in the wiring

That sounds above my pay grade, I'm afraid. I've attached he only PDF I have that mentions exterior lighting. No idea if it's outdated or now (credit to ynguldyn; more HERE).

Thanks, not quite what I was looking for, but interesting information

blue dragon did you ever figure this out?

Haven't tried. I would imagine it's similar to the f30. I'd did the rear fogs on my F30 and while you could enable it by filing down some tabs to enable the switch, I opted for the euro switch plus coding

I want to get the euro switch. But I cant seen to figure which switch I need for my X1. And all the ones on eBay all state they will not ship to the US.

Did you figure out coding?
I've change the switch but can't code it to work.

NSL_Verbaut = Verbaut
Mapping_Nebelschlussl_L_output = nsw_l
Mapping_Nebelschlussl_L_Function = nebelscheinwerfer
Mapping_Nebelschlussl_R_output = nsw_l
Mapping_Nebelschlussl_R_Function = nebelscheinwerfer

I've made this changes and fog light still doesn't work.

Did you get this work? I'm still waiting for my X1 to come out of the body shop so I can install the switch you sourced for me.

Yes, it’s working fine

What did you to get it to work? I finally got my X1 back swapped the switch. Thought I coded it. But now the front fogs do not come on and the rear fogs still don't work.

mikeyb74 kubax86 : Did you guys get this figured out? I was going to buy a euro switch on ebay. Was it hard to install..
Any tips/tricks?

Someone recently did this on an x2 and the dash is the same, they just modified the blank in the switch location under the front fog switch, may want to look over in the x2 section.

Although not residing in the USA, I read this topic with some alarm.
Here in the UK, my X1 and most other recently manufactured cars have rear fog lights. I find following cars with them switched on to be one of the least pleasurable experiences of driving.
The reason why? Well, we only have to see a bit of mist when out on the road and substantial numbers of 'numpties' think ' wow, I'll switch on my fog lights (front and rear).'
They then dazzle the driver of any any following (or approaching) vehicle, which in itself can lead to accidents. Worse still is that many of these 'drivers' forget to switch them off when the mist clears, making matters even worse. We had a misty/foggy day in the English Midlands a few days ago and there were numerous vehicles showing their foglight through the day (although most of the mist was cleared by late morning).
Again, I don't know what regulations cover use of foglight in the USA, but here in the UK it is an offence to switch them on except under specific conditions and here's what the law states:
'You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights but you MUST switch them off when visibility improves (see Rule 236).'
Here's what Rule 236 says:
'You MUST NOT use front or rear fog lights unless visibility is seriously reduced (see Rule 226) as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.'
I apologise to our friends in the USA for having this rant, but I think fog lights are, in reality, more of a nuisance than an aid except in the very worst of conditions. Incidentally, the LED rear lights on my X1 are bright enough for driving under most conditions without having to resort to using the fog lights.

No need to apologize, I see zero reason why anyone needs these to function in the US considering that most US drivers can't properly use high beam headlights or front facing foglights.

Thank you, I'll have to check this out.. Interested to see about them being able to pop-out the button, reminds me of the 3-series I had.

The US doesn't typically allow for rear fog lights (Though I've seen a few Lexus Sedans with them). But my usage is for dense fog - Up in the mountains there are days where you can't see 3 feet in front of you. I had rear fog lights enabled on my old 3-series and it definitely helped keep me visible to others (Typically people use their emergency lights)

All US Volvos have them, and have since the 1990's. It's a constant source of amusement on Volvo forums when people discuss whether they're useful, legal, or burned-out-on-one-side.

Well yes, in that sort of scenario I'd be doing the same. Back in the days when I was young (pre-history 1960's my sons say!) we used to have smog so dense that I'd occasionally have to drive home, from one end of the city where I worked, to the other in fog (smog) so dense that I had to drive with my head out of the sliding side window (not easy) of my old (original) model Mini 850cc to try and find the white line down the centre of the road! No-one had thought of rear fog lights in those days although you could fit the sort of front fog lights the cars would use in the Monte Carlo Rally and dazzle every one else on the road. .

That is some thick smog! I've seen it get bad in Los Angeles but not that bad.
I bet that mini was fun to drive, could even pick it up and move it if needed

For anybody else curious of the outcome. I pulled off the plastic switch (pry tool) shaved down the 3 tabs, coded using BimmerCode and had success. It was extremely easy.

My (1963) Mini was great fun to drive - especially in snow, but not very reliable. You mentioned about picking it up, which reminded me of one of the faults with a very large nut between the gearbox and the engine (gearbox was in sump in original Mini). The nut was held fastened by a washer that was simply knocked (tabbed) over one of the large faces of the nut. Unfortunately, someone forgot to design the washer with a splined inner 'circle' to fit over the splined shaft, so it was very prone to dropping off, this potentially jiggering up the gearbox. I was lucky it didn't cause any additional damage, but a pal and I had to separate the engine from the gearbox to fit the new splined washer (cost a few pence!). To get at it all, we actually disconnected all the ancillaries and lifted the whole body off, rolled it back away from the engine and rested it on a large wooden block.
My son claims my X1 isn't a proper BMW as it's front wheel drive, but is just a 'big Mini', unlike his 2017 BMW 1 Series. Well, I enjoy my X1 and have covered just 20K miles in 20 months, so I tell him to get real!
