I have done many including beep on lock / unlock, digital speedometer, windows down with fob, but my NFRM is old module to have these done as DRL's.
The other thing, I wanted to do was to keep the cluster on all the time (used to it on my previous car) but could not do it on my E90.
Frob, give it a try and see if you can do it. Apparently I have NFRM1, and you should have NFRM2 or 3 in order to have DRL's and speedometer on all the time.
Away for 4 weeks. PM only if its urgent.
