TCU Recall on 2004 X5
 

Forgive me if I've repeated a question already answered elsewhere, but my searches have come up fruitless.

I today dropped my 2004 X5 (8/04 prod) at dealer for TCU recall (letter from NA advising that Assist module was malfunctioning). From previous posts since 2004, I understood that by replacing the 2004 Assist TCU with one from 2005+, I would gain the ability to use Bluetooth, which was lacking before.

As it is now 2007 and the dealer advised that the "latest model" TCU was installed, I believed I should now have functioning Bluetooth along with Assist.

Dealer advised midday that new TCU was installed, but they were having trouble pairing a phone with the Bluetooth.

Several hours later, Dealer called back and reported that "this" TCU did not, in fact, support Bluetooth--but I could buy one that would for about $1100.

I get the sense that something doesn't seem right with this assessment; but I'm not sure how to rebut when I pickup my truck tomorrow.

Am I correct in my belief that Bluetooth should now work in my X5? Or is my system still missing a component necessary for BT to work? Or is dealer being straight with me--the replacement TCU is different than others that are the BT/Assist combo used from MY 2005 on?

I appreciate any advice!

Probably using an old one off the shelf. Check to see what part number they used. You might also review this thread, where several of us had TCU's replaced last year.

Thanks for that...do you know if the 798 is still the latest for the X5?

Or rather, the 84-10-6-978-529?

Sorry, I don't. At least it will give you somewhere to start with the dealership. If they show you a part number of a unit older than the -798, you know you got screwed.
