Folding Mirror Coding Bimmers Feedback:


Okaii:I had to change both SPIEGEL_KOMFORT_EINKLAP in the NFRM and KOMFORTSCHLIESSUNG_FB in the CAS module from nicht_aktiv to aktiv to get this to work on my 2008 M3 with Comfort Access.


Nick:Hi, (2008 E93 without CA)

I had to change KOMFORTSCHLIESSUNG_FB and FH_KOMFORTF_MIT_SUBST in CAS and SPIEGEL_KOMFORT_EINKLAPP in NFRM to aktiv for the mirrors to fold in/out with the fob but on my car the alarm goes off within 30 seconds every time I lock it without pressing the fob button twice to disable the interior sensor.

Gang:This works on a 2012 (LCI) E92 M3, again by setting ASP_KOMFORT_EINKLAPP = activ in the NFRM module.Thanks for the guide. I’d done a fair bit of coding on my E46 M3 so this wasn’t all new, but very helpful none-the-less for the important bits of magic.

Leno:I’m new to the Bimmer family as I just picked up a 2008 BMW E60 sedan. I watched many “how to program” youtube videos but yours hands down makes allot of sense. Question for you… any specific programming cable on Ebay that I should purchase to program my car? Thanks.

Reply:check the port on you drivers side floor area, some look like a big block plug labled ODB, and others look like a computer internet cord. However sellers list it buy make and year if compatible.


Eges:I can not find the KGM all I see is KBM and KOMBI

Answer:Different years called the ecu modules different things. You will have to Google it. I had the same problem with a few mods I did and discovered the module under a different name.
