Hi,

Can you look over this for me and see where I'm going wrong?

2010 E91 LCI TCU only, Aux only, Pro nav

Added a BN2000 Combox, shaved down the BT aerial tab and plugged that in.
plugged in MOST ring
repined plug as per picture below, nothing with power in 2 so tried power in 1 and same (only have one power wire it seems some guide surges having 2)
I had a blue and a brown left over in my TCU plug so read somewhere else to add the brown to COMBOX pin 14 so I did, no change

when I unplug my MOST wire I get a red light in the wire on one side. but no red light on the Combox? which seems wrong?



Coding:

I changed my VO to as follows in the pics but basically changed date to 03/11
Delete $633, $612, $616, and add the following instead: $614, $615, $644; $6AL; $6FL; $6NF; $6VC and $6NR

process ecu

MEDIA shows in here

FA WRITE to CAS

FA WRITE to NFRM

this works

SG CODIEREN TO CIC

this works, can see bluetooth audio in the idrive

SG CODIEREN MEDIA

this fails, says coding active then coding failed with the below message which kinda hints at my Combox wiring?


in idrive when I click bluetooth audio it just stays on please wait?


thanks!

My options now,

until you will not get CMEDIA in identification job, you may not try to code it

but you sould understand that your packet to CMEDIA goes thru 2 CAN bus gateways
JBE translate from OBD to K-CAN and CIC is traslate it from K-CAN to MOST bus
so you need code them as well, and specifically code MOSTGW, may be they have to update their gateway table with new recipient

Thank you,

It shows up in NCS now as an ECU from choose ecu but that’s probably just as I added the $6VC VO?
Hence I thought I’d check the INPA

Ah so when I did the

SG CODIEREN CIC
I should then do the same for MOSTGW

Before I attempt the media one?
Then hopefully the media will be successful?

I’m a bit new to coding and on the steep part of the learning curve so thank you !


Also a bit concerned I don’t have any red lights on the combox MOST in/out plug?

The plug and wire its self have one side lit up. But I’ve read the COMBOX should have a lit up terminal?!

[ptpending]

you need to get red light from combox too
if you didn't, then you didn't powered it, or module is not working or you have fuse burned for this circuit

Going to get a multimeter and confirm 12v across the power terminal (1 or 2) and the brown earth wire. Start from there

If that works I’ll switch the power wire to 2 see if that helps (can’t recall if I tried that after adding the earth)


From there it’s probably another combox !

[Andy198712]

Okay, mostly success!

Confirmed 12v across the pins.

Tried the power back in pin slot 2

Plugged it in and had a red light on and off again slowly. Result !

Plugged it in it works! Can see the previous combox owners linked phones then added mine and can get music to play!

Got very limited office and no apps but tbh I don’t have the armrest USB yet so not especting the world yet!


Thanks for your help, think I still need to code the MOSTGW or no as it’s working now?


Guess it means I got a tele combox?!

[ptpending]

i would code them
but i think i've also had upgraded the CIC code to newest version too

[Andy198712]

Guessing I need the ish for internet ect and apps like Spotify?

I think that comes into play with the apps is that right? Should they show up on the idrive? Might be that as it’s an older combox, I’ll try check the software on it all

[Andy198712]

Saying that.

I still havnt re done that SG CODIEREN MEDIA step as it failed before so I guess that’s a the first thing to do and while I’m at it MOSTGW then ? With the new VO is that what it’s telling those modules?

[ptpending]

the best way is
upgrade firmware in all modules
cic uppgrade will require 1-2 hours , you need external charger to finish that
code all relevant modules

if you cannot upgrade now, then code gateway modules,cic and then code combox

Thank you for the help!

Is that via I COM cable? Might have to find somewhere that can do that for me in the future, like you say. Short term I’ll code those for now and look at adding USB,
Hardware wise is it literally the plug/socket for the armrest and a long enough cable to make it to the black round plug on the combox?
