Bluetooth unstable connection after VO

Hello

I recently bought a 645 that was equipped with the stupid professional phone. So it had the 638 option. Its has the professional CCC with voice command.
I used NCS to remove $638 from both CAS and LMA and added the $633 option. I then changed some settings in the files to allow Bluetooth from other devices and disabled the SIM bits.
Currently I am at the stage that I am able to pair my phone, Insert SIM screen has been removed and was replaced with Please activate your phone. My phone pairs (I tried other phones as well) but keeps disconnecting.
My production date is 07.04 for the Bluetooth module.
Do I have to replace the TCUM at the back or there is something I am missing here?
I though you only replace them if you cannot pair.

Thanks!

The TCU needs a firmware update and then default code CIC/TCU/MULF(if equipped) with the updated VO

i read about defaulting the modules but how do you do it? Just empty the MAN file and push it to the module? Or untick the checkbox from the profile?
Can the firmware update be done individually for the TCUM? or the whole car needs doing? BMW here doesnt want to do upgrades to 04 models anymore as they are too old..

those are instructions on default coding, you need to default code the module after changing the VO to get the updated settings.

As far as the firmware upgrade, that is done with WinKFP

ok just to give an update here as someone might have similar issues.
I upgraded the TCU module to the latest version (it took 80 minutes!) and then defaulted it using NCS but I still have the same problem. The phone pairs but cannot connect for more than 5 seconds.
In INPA its telling me something about the antenna but if there is no antenna I guess that I wouldnt be able to connect at all (and the cradle phone as well)

What do you mean there is no antenna? it should attach to the TCU via a FAKRA style cable. I think it is purple.

What is the model number of your TCU??

Its made by Motorola

well tried the vo change to 612 and enabled bmw assist and the only think i managed was to get an SOS error.
I also tried to pair it with my laptop in case the android was not compatible but same think happens. Connects for 5 seconds and disconnects. Keeps going on like that forever.

you're default coding the CCC and TCU right?

Yes always. Maybe i should try to remove 633 and add 644 instead. I think 633 only works if you have bmw assist?

I think the MULF from the earlier cars (2004) only works with the BMW handset.

You should use "ExpertMode" in NCS Expert for default coding rather than blank MAN file.

I would suggest you pick up a ULF2 on EBay and install that. You need to default code it. If you want to have your correct VIN displaying then you also need to use Tool32 to write your VIN to it. That is an easy thing to do, load ulf2_60.prg file, select FG_Schreiben (double check for exact function), copy the vin as read from your car by NCS Expert (on main screen, it might have a "v" after the vin number). Then select "Run job once".

i give up. i tried everything with this TCU and nothing works. I think it is not a full bluetooth module and only works with the motorola handset. I need to source another one but which type I am confused.
My car has the SOS button so it has to be the telematic one?

Here you go, this will explain the differences:

http://www.e90post.com/forums/showthread.php?t=1181654

As I said go for a ULF2 and retrofit, code out the SOS button if you can't get it working with ULF2, but you should be able to.

but i thought MULF2 also supports USB and my car being 2004 cannot have it?
By the way, can I flash another rom into my TCU? I dont care if I break it since its useless now. I was thinking that I might be able to update the bluetooth stack with a new version.

i fixed my problem by replacing the old TCU unit with a newer one. The new one is a TCU 1.5 version from a 2009 model.
Plug and play. Default coded and now my phone pairs and I have a phonebook right away. I also have the SOS function enabled so in case of an accident it will automatically trigger the services.
Bought the new TCU for 40 and sold my old one for 25 so 15 for bluetooth!
I cannot display Unicode character though even though I enabled it through ncs
