Many thanks for your quick reply, that's good news then! I have checked the latest TCU available in the USA which is part number 84109195455. Will this be compatable in the UK or will I have some problems with it. There is a part number for the UK one but I don't think it is as late a build as the US one!

I think that the US TCU would work OK in the UK, but I do not know for absolute certain. The main difference is the cellular band that the BMW Assist and wired telephone operation on. However, that is not involved at all with the Bluetooth, so I doubt that it matters.

I've had a similiar problem since my wife changed her phone.
Car 04 325 cI C with ULF. Phone is a Verizon Env3. Prior phone was a RAZR V3.
Even had my dealer try to pair it with the Verizon Env3 .. no luck..
It WILL pair with my son's BT ear piece, and I have not tried it with my 06 X5, which pairs fine with my LG 8300.
I don't know how to tell which ULF or TCU ( I do have Voice Reco in my X5), I have, but if I am able to successfully pair her phone to my X, can I assume that upon discovering what type of device is in the X and version ie, TCU vs ULF and Gen #, if I replicate it in an E46 will her phone work?

Thank you
ED

Try disabling the phonebook pairing and see if that helps. The Env3 phones seem to have mixed experience with people.

My two year old BMW battery is dead on a 02/2004 build X5...
Performing SIB 61 08 00 "Closed Circuit Current Measurement " shows 286 milliamps being drawn once the 16 minutes have elapsed and the vehicle goes into sleep mode. It should be less than 40 milliamps. While still measuring current, pulling Fuse 74 immediately drops the current to 21 milliamps. This tells me my Everest TCU is not powering down.

Looking at the 45+ SIB's on Telecommunications I only found SIB 84 01 04 which states the following:

SUBJECT
Service Action: Check and Replace TCU
MODEL
E46 (3 Series), E85 (Z4), E53 (X5), E83 (X3)
SITUATION
Low ambient temperatures (below 32°F) may cause the TCU (Telematics Control Unit) to go into reset mode.
The result is that calls to BMW Assist or "SOS" calls will not be completed.
Once in reset mode, the TCU will remain in this condition even with the ignition turned off. This could result in a discharged battery.
This Service Action will check the TCU and replace it if necessary.
...
AFFECTED VEHICLES
This Service Action involves E46 (3 Series), E85 (Z4), E53 (X5) and E83 (X3) vehicles which were produced from 8/2003 to 11/2003.


Has anyone found any SIB which indicates more recent TCU's have issues powering down? If the The Non-Volatile Memory (NVM) within the TCU has been corrupted (see SIB 84 07 07) can this cause it to not powerdown?

This is a TCU retrofit thread. Your issue is totally unrelated. You might have better luck if you start a brand new thread with this question.

I posted the question here as those who are adding a TCU need to be aware of all the issues BMW has had with the past parts... hence my comment about the 45+ SIB's which exist since 2003. Perhaps a list of these bulletins would be more value for the thread.

I was actually hoping you or kiwijochen would have an answer!

Ok here is a new challenge for everyone (looking at Brian and Jochen )

I have a 2003 Range Rover with MKIV Sat Nav, DSP and built in telephone module (the kind you put a sim card in) with an eject box in the arm rest.

It has voice recognition now, and i can control the nav and phone by voice.

I want to upgrade to bluetooth (either by TCU or ULF but prefer TCU because of price, and the fact i wont require a pairing button).

Obviously I already have the microphone, but i doubt there will be an antenna so i will purchase one of those.

My question is will the TCU or ULF module work? and would i remove the current phone module (whereever it may be) and replace with the TCU or ULF module?

I'm willing to experiment, and use navcoder/post results so everyone can share the info.

Cheers

This is quite straightforward:

1. Determine exactly what type phone you have now, as per WDS
2. Remove old telephone control unit
3. Adapt wiring of telephone connector (if necessary) to suit TCU
4. Connect TCU and code as required.

You are not the first to do this...

NOTE: you will currently have a separate SES module for voice recognition (VR), you can choose to retain this or replace the VR with the TCU VR (TCU = phone VR only)
