On my 2011.5 M3 there's no need for the little lego block trick as the button extension is already in there. So technically this mod is FREE.

All you have to do is take the button out (I have my own DIY but there's a few good DIY's on M3Post already), then trim off the four little tabs that is preventing it from being functional. Once trimmed the button will work and function fine. The only thing is the button will not have the rear fog light icon as in the euro switch. I prefer it this way so the car still appears stock US spec.

Once done you will have working rear fog lights to help illuminate behind you as you back up or whereever your imagination takes you.

Nice DIY. Does anybody have photo(s) of E90 tailights lit up that had this done? I don't think the narrow white backup lamps light up on E90's.
