  3. I have had to replace the PS mirror. The new mirror doesnt seem to repond. Does the mirror store the programming or is will it pick up the coding that was stored for the old mirror ( physically broken , but working electrically)

  5. This code change will work on a 2007 335 XI sedan (E90). If the vehicle does NOT have the comfort access package, then parameter KOMFORTSCHLIESSUNG_FB in the CAS module will also need to be changed from nicht_aktiv to aktiv.

  6. 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.


    October 19, 2015

    • Thanks for this info. This extra field made it work on my 2009 335i E90

      09 E90

  7. Hi! Will this work on an 2015 320d?

  8. I can’t access the NFRM module.

    COAPI-2041: Wrong ECU coding index A_PL2FRX:CODIERNDEX=33h FRM2_E89.C08: CODIERNDEX = 08

    COAPI-2041: Wrong ECU coding index: CODIERDATEN_LESEN

    • Did you ever get the issue of unable to access NFRM sorted out? I have the identical problem. Also if you look at FRM2_E89.C08, it has a file size of 2Kb. The other files are somewhat larger. NCS Dummy reports the file as basically empty.

  9. Works on my 2010 E90 using parameter:


    rather then the one shown in guide, coding for the timing is still the same though

  10. Hello coding friends, i can confirm this feature works on a E90-2005/03 !! Thanks for this usefull website!

  11. Confirmed working on 2007 E92

  12. 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.


    October 17, 2016

  13. 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.


    December 9, 2016

  14. This worked on MY0909 LCI 320 with comfort access.
