US cars can have the rear foglights enabled by replacing the light switch with the Euro version. These are the same lamps already installed as adaptive brake lights. While the rear fogs are switched on, the adaptive brake light function is disabled.

Parts required- 61 31 6 932 796 Switch

Tools required- flat blade suitable for prying trim pieces

First remove the trim piece with AC vent directly above the light switch. I found it was easier to start on the inner end near the speedo. Here what it looks like after removal.





This shows the clips that hold the trim in place



Now pry out the light switch with its trim piece.



Remove the cable by rotating the connector clamp.

Remove the trim by pressing in on the clips and move the trim to the new switch.

Re-install the switch and trim pieces and you're ready to test.



The rear fogs can be switched on only when the fronts are on.



These lights are very bright (21 watt halogen) and can be very annoying to drivers behind you, especially at night in clear visibilty conditions.

Apparently BMWNA thought US drivers couldn't be trusted to use these lights responsibly. Let's prove them wrong.
