Replace TCU by MULF2

Hi, I have BMW radio professional and TCU unit in the trunk on my E92 2009. I would like to add USB functionality.
Could I simply replace TCU by MULF2? Are sockets on TCU and MULF2 the same? Would I need some kind of socket adapter wires?
I would loose only SOS button by doing this replacement?
I would need coding?

No support for SOS anymore by BMW in the US so you
already lost it. Due to its only 2g and there is no 2g anymore.
Yes coding is necessary.

Yes you can do that but it might be easier to do this.

My car is from USA, but I live in Lithuania currently, I wonder does SOS button work here in Europe?
If it does not work that makes perfect sense to remove TCU and install MULF2. Its a bit cheaper than "Bluetooth Streaming Box" as I prefer USB, and its maybe more clean to have one MULF2 than TCU+BluetoothStreamingBox.

I will test SOS button tomorrow and see what does it do.

But the original version of the streaming box has both
and sd slot and a usb slot both of which play music files.

Here in the state 2g is history and also it was a pay for it
subscription service. Don't know about the rest of the World.

This one

https://www.ebay.com/itm/Bluetooth-U....c100005.m1851

Which is actually the one in the installation link.

For now I am interested in USB only, I hope I wont want bluetooth later...
I tried pressing SOS button today and it seems that it does nothing. I think it might be coded out already, how could I check that?
I tried reading 2URAD and TCUM with NCSExpert but getting this error for these modules (I can read other modules fine):

How could I fix it and read 2URAD and TCUM?


P.S. It would be nice to map SOS button to some kind of function, like turn off traction control

First of all do you have Inpa working?
Looks like you don't if you are getting cable
errors.
Go to functional jobs in Inpa an readout
the hardware with the F2 and F3 functions.
Do this before preceding to NCS when you get the cable
working.
You should list the year and model of the car.
And I would go to one of the free vin checker sites and
find out the options the car came with .
SOS If you pulled the fiberoptic from the TCU that would tell
you as you would induce and SOS error but why do that when
you can read the cars modules with Inpa.
See bimmerprofs page one Inpa functional jobs.

Yes I realize streaming data is of lesser quality than usb but this box has
USB and SD slots.

I had done some coding with NCSExpert before like removing TPMS and coding it to work with FTM. So Inpa and NCSExpert should be configured correctly.
This is what I have read with same cable and same PC setup:


Where could be the problem?

In NCSExpert it writes as 2URAD. Not sure why NCSExpert has different module names?..
As I understand you cant read 2URAD (RAD2) and TCUM (TCU) modules with D-Can cable from ebay. Only code them with VO values. Hopefully I wont need backup.
I will think about which module its better for me to buy, and will need to wait for shipping... I will write DIY after if I will have success.
Also found some detailed article on similar question https://www.babybmw.net/forum/viewtopic.php?t=54406

The earlier cars pre 07 could program Most Bus modules
without Icom. I think the cutoff date was 3/07 build in the US.
This has always been a nebulously defined subject
Some of the guy on the coding board say a VO code gets
around this . But you can't manipulate individual parameters
that way as as far as I know.
Also I wonder if putting modules in from newer years stops
you from being able to code those modules even in older car.

Changing the production date of the car to get it to load new
software on an older car seems to be one of the tricks often used
for Mulf 2 Hi installation. That one and the USB Radio retrofits
are the ones I know about.

Getting changes from L7 to Hi Fi or vicsa versa seems to be
another one where Icom is needed on newer cars.

I know the name of the Radio software changed at some point.
Some people have had problems with mulf and other options and
have had to update the radio software or get a more uptodate
radio. Also this is another vague area.

I got offer with great price for MULF2 in my local area so I could not resist and bought it. I already switched it with TCU.
Changing places TCU to MULF2 was not hard, though TCU connector is a bit different so I needed to trim connector a bit to fit to MULF2.

I did not do any coding yet.

I am getting SOS error in instrument cluster.


I already saw USB icon on Radio, when clicking on USB icon I get "Insert" message (don't have USB cable, so cant test it, shipping from ebay will taike time...) so it seems to work?



But I don't see Telephone icon any more, so I guess Bluetooth is gone...


Is this what I need to do to disable SOS?
Code:
KOMBI:
TCM_ALIVE_MONITOR -> nicht_activ
TCM_ID_MONITOR -> nicht_activ
Or do I need to remove something from VO?

What about bluetooth?

I also noticed that AUX is not working any more. I guess its switched to MULF2 AUX? How to switch it back to radio AUX?

From posts on the coding board its either 6fl
with the aux coming from the mulf combox or
not . No choice .

Be careful of the spelling of activ
I think its spelled with a K aktiv
compare it to other aktiv spellings.
You should only have to remove nicht anyway.

I believe you have to repin the connector or buy one
of the adapter cables for the TCU.

Bluetooth is contained in the Mulf module to for phone.

For coding I have done this for VO:
Removed $639
Added $644 and $6FL

Reset to factory defaults:
CAS, NFRM, KOMBI, FZD.
After reset I saw changes only in KOMBI:
Code:
TCM_ALIVE_MONITOR
	nicht_activ
TCM_ID_MONITOR
	nicht_activ
CBS_SCEN_01H
	nicht_aktiv
CBS_SCEN_02H
	nicht_aktiv
CBS_SCEN_03H
	nicht_aktiv
CBS_SCEN_04H
	nicht_aktiv
CBS_SCEN_06H
	nicht_aktiv
CBS_SCEN_07H
	nicht_aktiv
CBS_SCEN_10H
	nicht_aktiv
CBS_SCEN_11H
	nicht_aktiv
CBS_SCEN_12H
	nicht_aktiv
CBS_SCEN_13H
	nicht_aktiv
CBS_SCEN_14H
	nicht_aktiv
CBS_SCEN_20H
	nicht_aktiv
CBS_SCEN_21H
	nicht_aktiv
Also in MULF2 HIGH I wrote my VIN with Tool32 -> ULF2_hi.prg -> c_fg_schreiben.

SOS error does not appear any more, but Radio shows all the same menus as before: USB with "- -" icon, no Bluetooth and BMW assist is still there.

I believe I need to reset 2URAD (RAD2) to factory default?
But When I try to do SG_CODIEREN (or CODIERDATEN_LESEN) I get same error as before:
Code:
2020       Error LFCDHDIA.CPP (A_E65MMI.IPS/IPO) CDHapiResultText     1
SG antwortet nicht  IFH-0009: SG nicht angeschlossen oder meldet sich nicht  RAD2
I also tried to do SG_RESET on 2URAD (RAD2), Radio screen went off and on but nothing has changed, all the same menus are there.

Any ideas?

Did you read the file in the 2urad it lists which options
are turned on and off. I believe ulf is the Mulf or usb .

when you change the VO it does not change the module
till you default (VO code the module)

Lessen means to read in German so
coderiedn lessen literally mean read the code.
Not write the code.

https://www.bimmerforums.com/forum/s...ith-NCS-Expert

To remove SOS at the VO level I believe -Teld or +Teld is used
You should really move this to the coding sub forum as these
are all coding questions.

SG does not answer IFH-0009: SG not connected or does not answer RAD2

The guy in the following thread where struggling with the
2rad and 2urad problem

Below is my thread where I retrofitted a MULF2 HI into an 06 using the TCU wiring. Your current aux wire may go to the head unit so you may need to run a new one to the trunk. If I were to do this mod again, I would just hook a tune2air (bluetooth music) to the MULF2 HI and leave it in the trunk. ebay has some generic standar USB to bmw USB connectors. Aux in is a few new pins added to your TCU wiring.

Most MULF2 HI have the bluetooth phone disabled. In the US, they are normally just used for USB. You may need to enable BT in the module via coding.
