It worked on mine.

I'm curious why some folks did not need to code.

[MCanadaE46]

Does anyone have a picture of what this looks like on the 2016 F80's?

Also, can someone help answer some of the questions I posted in this thread...

I wish there is an actual, factual... button lol. Like names and everything instead of it being blank.

That will drive me nuts.

[MFNATIK]

Ok, that was seriously the easiest mod ever! The button popped out without much force using the pry tool. Used a new razor and it just took those little tabs off like they were butter lol

I actually used to use mine on the Freeway when a DO-DO bird is tailgating me at 65MPH....switch on, they slow down pretty quickly and back off.

My only question is why are you driving 65mph in an M4? LOL

You could install this into the middle of the OE button (and probably figure a way to wire it to illuminate the symbol when activated).

Price is right. And, there is plenty of other "silver" on the dash.

Just an idea.

Just an idea.

The EU F8X headlamp switch will place icons in the buttons and illuminate when pressed. Or purchase the F3X version to get the foglamp icon, which can possibly be used for something else later on.

This is today my first coding exercise with my car. Finally got to code something myself.
Prior I had used a fellow expert to code a lot of other stuff.
Yeah!!.

Free mods are the best. A popular early mod on the previous E9X chassis was the Rear Foglamp, or Euro fogs.

Rear fog lamps (or "fog taillamps") have since the 1970s been mandatory equipment on all cars sold in countries that adhere to European (ECE) vehicle safety Regulation 48, which governs the installation and hookup of lights and reflectors. But, they're only just beginning to show up on US-market cars. They are intense red lights manually switched on by the driver in conditions of very poor visibility (heavy fog, rain, snow) to increase your car's visibility to vehicles behind you. A rear fog lamp is very much brighter than regular taillights, and is in many cases even more intense than brake lamps. Regulations in most of the world, including North America, permit vehicles to be equipped with one or two rear fog lamps. If only one rear fog is fitted, it must be on the driver's side of the vehicle. It's safest and best to have just one rear fog, much as it offends the sense of symmetry of those who don't know any better. Having two is legal, but makes it much more difficult for following drivers to see a change in your car's rear lights when you step on the brake. Many vehicles that do come from the factory with rear fog functionality have rear fog optics and sockets on both sides, with only one wired up -- this isn't a factory oversight. It's done this way because the "driver's side" of the car varies depending on which country the car is sold in!

The headlamp switch is very similar as a base F30/F32, which is equipped with front foglamps. These buttons are "blank" on the M models by injection-molded "stops", which physically limit the button from being depressed.

While the quick and easy way to accomplish this would be to order a Euro Headlight switch, but where's the fun in that? Instead, we're going to mod the existing US switch.

Let's begin.

1. Remove driver's side air vent, pulling slightly on outward edges


2. Remove Headlight switch, press on (2) outward retaining clips and pull


3. Disconnect headlight switch connector


4. With headlight switch on bench, slightly lift on (6) retaining tabs and separate halves


5. Pull apart plastic housing from headlight switch


6. In this image, you can see existing buttons for Front (upper) and Rear (lower) foglamps, even the Front foglamp LED is lit on US switches when powered on. Rear foglamps when activated will illuminate an icon on the instrument cluster after coding is completed.


7. Position of switches, we will be working with the rear fog (bottom switch) only


8. Press bottom switch out from backside




9. Injection-molded plastic "stops" are integrated on US switch assemblies, these will need to be carefully removed with a hobby knife or razor. There are (3) stops total (two on other side)




10. Reinsert Rear Foglamp back into headlight switch


11. Completed shot, with Rear Foglamp button depressed for illustration. This will be pressed back out flush when reassembled back together.


12. Reassemble headlight switch housing, snaps back into place.


13. Reinstall headlight switch and air vent back into place

Coding

Coding is required for the switch to operate.

REM Module

REM -> Mapping_Nebelschlussl_L_output: nsl_l
REM -> Mapping_Nebelschlussl_R_output: nsl_r

FEM_BODY
3060 NSL_Verbaut: verbaut

Operation

Once coded, operation is exactly like if you were equipped with a EU Headlight switch. Simply flip on the headlamps, press the bottom headlight button and we are greeted with our new Rear Foglamps:

Standard


Rear Foglamps Enabled


As an added bonus, an amber Rear Foglamp icon illuminates when button is activated:


This and much more covered in our journal thread here: http://f80.bimmerpost.com/forums/sho....php?t=1020487

So simple and easy, thanks for this mod!

[STOOF]

I found stickers for the switches!

Comes from the UK but only ~$10 after conversion.

Thanks for the DIY! The bread knife trick worked awesome (took me literally 5 seconds to pop out). Only coded the driver's side rear fog a la Mercedes style.

Why would you want that? you drive a BMW...and it would just look like one of the fogs was burned out lol

...Or get mistaken for a motorcycle in a dense fog

Lol. I've read if only one rear fog is working it doesn't look like your constantly applying the brakes (and God forbid you get that non-complacent driver tailing you who won't realize when you're actually stepping on the brake).

You guys convinced me to code the right side now lol...
