Bluetooth module location

Hi all

I know this has been asked several times, but I haven't found an accurate answer yet.

I have a 2008 BMW X5 E70 (RH Driver side). The bluetooth module seems to have stopped working. Can you tell me where this module is in the car?

Note: I asked this last week and for some reason my account was disabled and the thread deleted, so I didn't see any of the responses that were posted. Thanks to all who had replied!

Thanks in advance.

I am not certain that there is a Bluetooth Module, but that it is integrated in perhaps the Telecommunication unit.

Bluetooth is in the TCU (Telematics control Unit) which also handles all the BMW Assist functionality - which ofcourse no longer works since the telecom network that supported it has being turned off !

If however you're car also has option 6FL - known as USB Audio with a USB port in the center console, then bluetooth functionality is handled by the MULF2 box. TCU is also present, but only handles BMW Assist.

replacing the TCU or MULF2 if you have it will require coding to your car VIN.

Thanks for the reply.

My first course of action is to find the unit and see if there is anything obvious wrong with it (e.g. loose cable). But... I'm still no closer to anyone being able to advise as to where I can find it...

You were given the name of the module and a link to the BMW service manual. Which includes system description, diagrams, wiring diagrams and locations of every connector.

And you are 'no closer'??????????

The people in post #2 and post #3 each provided links to www.newtis.info.

Go there. Spend more than 30 seconds. It is quite dense and challenging to get your arms around it, but once you understand how it is organized and how to navigate and piece it together, it is an invaluable resource


Edit: they linked to specific sections. If you back out and go in the front, you will see how it is organized....

Thanks for the reply. Excuse my ignorance, but all I see when I click on those links is a bunch of search results (none of which make mention of bluetooth location) - so at first glance this appears to be the equivalent of someone telling me to 'google it'.

I had hoped this would be a really simple question with an answer something like 'look under the drivers seat'. I didn't expect that I would have to start trawling through technical wiring diagrams until I find something relevant.

But, thank you for informing me that 'tis.info' is in fact some kind of BMW resource and not just some random search engine - I will take a further look.

I linked a whole Bluetooth section of Newtis. This is the realoem.com of the location of the Bluetooth antenna. Only part that comes up as “Bluetooth.” https://www.realoem.com/bmw/enUS/sho...21#84506928461

Thanks Zulu95 - that's what I was looking for.

So, for future reference to others, in an X5 E70 it seems to be located above and behind the left side rear wheel. It can be accessed by pulling off the side panel in the luggage compartment. There are 2 metal boxes - I assume it is the top box because it has the bluetooth symbol on it.

We were trying to teach you to fish.

Across the top of the page that you say was 'just results' you will see a nested address. "home" all the way on the left. Click on that.

On the next page enter your VIN

you will then have the service manual (technical information system = TIS) for your car.

Have you checked the codes . If the TCU has failed or HW fault then it should have logged an error.

No I haven't. How do I do that? Do I need some special equipment?

It is located in the Trunk, behind the Left side Plastic Panel.

I once had to change mine, several years ago, with one I bought on E-Bay. It's still working very well till date and I didn't have to code it. However, the BMW ID bears the last VIN digits of the dismantled Bimmer from which it was removed; that never bordered me since my SOS subscription had long been expired.

You are correct but it does not limit the functionality.

However, the BMW ID bears the last VIN digits of the dismantled Bimmer from which it was removed; that never bordered me since my SOS subscription had long been expired so didn't see the need to spend the extra quid. It showed up just the one time you are pairing your phone with the vehicle and if you hadn't known your original VIN before then, you wouldn't be any wiser. :-)
