Coding e70 trailer hitch

[jwalker87]

Hello all - long time e90post forum member, but just picked up a 2011 x5 35d a few months ago. Installed the factory trailer hitch and wiring harness, and now on to coding. I found several threads and comments throughout the internet, but none really summarized everything neatly into a "this is everything you need to do to code for trailer hitch installation." The closest was probably THIS thread, starting on Post #55.

Anyhow, I compiled the attached directions as best I understand them. Can anyone that has done this coding verify the correctness/completeness of this?

Thank you in advance!

Maybe reach out to this guy, Post #51 he installed OEM hitch and looks like he did coding himself: https://xoutpost.com/bmw-sav-forums/...-m57-x5-6.html

Thanks! I reached out to him. Also, I'm super jealous of the time he has to tweak his x5 to his liking. I remember when I was childless...

Just got done coding - we'll see how it goes. I did the VO add, and then just coded the modules individually since I'm a bit uncomfortable with the 'write vehicle' option. Ended up making the following changes; the others identified in my PDF were already at that setting.

KOMBI Module:
AHM_APPL_MONITOR - from nicht_aktiv to aktiv

RPDC Module:
ANHAENGERKUPPLUNG - from nicht_aktiv to aktiv
AHK_OFFSET - from offset_0 to offset_1
AHK_AUSBLENDUNG - from nicht_aktiv to aktiv

CIC Module:
MACRO_TRAILER_COUPLING - from nicht_aktiv to aktiv

AHM Module:
CCMELDUNG_ABRISS_AHV - created entry and set to cc_04bh
CCMELDUNG_FEHLER_AHM - created entry and set to cc_04bh
CCMELDUNG_VERRIEGEL_AHV - created entry and set to cc_04bh
START_CCM - created entry and set to klemme_15
TYP_AHV_SG - created entry and set to keine_ahv
SL_BEI_KZL_AKTIV - from aktiv to nicht_aktiv

So is everything working correctly with these coding parameters? Is this all-inclusive for the coding that needs to be done for trailer hitch?

Currently it is not - I don't have a trailer to test the lighting operation, but the trailer-zoom backup camera feature, at least, is not working (option is grayed out). I verified the coding of the modules is as I specified above, but am somewhat stuck right now. Once I can get my hands on a trailer I'll test the lighting operation and go from there, I suppose.

Update: I'm an idiot! Or at least not as smart as idrive. I normally use the birds-eye-view mode of the backup camera, but I switched it to the normal-view today and BAM, hitch-zoom-view is available and working! Not sure why it depends on that since it's a completely separate menu option, but oh well.

I'll still try to find a trailer to verify light operation, but everything appears to be working well for now with the coding I've documented here.
