Dead ULF?

statdoc · #1 01-23-2010, 08:18 PM

Suddenly a couple days ago my phone stopped connecting via Bluetooth. I power cycled the phone, made sure the BT was on, set it to search, and still nothing. Then, I deleted the BMW from the phone pairing, and tried to re-pair the phone. That is when I found I couldn't get the "Activate Phone" to come up on the car screen. I no longer have any response when I push the Voice Control button. Lastly, I now get nothing when I push my BMW Assist SOS button.

Is there any other possibility besides a dead ULF module? If so, is there anything else I can try, short of purchasing a new module from the dealership?

Hi There,

I am in the same boat as you. Having the same exact issues. Furthermore, none of the lights come on next to the NAV screen. The phone option is also gone from the NAV screen. One thing i have also noticed is that it seems the Bluetooth is always on even when the car has been powered off. At first I thought it was my phone acting up, but I used my wife's blackberry and searched for bluetooth devices. Sure enough, if found the X5, even though the car had been turned off for hours.

I hope someone can provide a way to manually reset the ULF box. I have an 2006 3.0 X5.

FYI: I fixed my issue by disconnecting and reconnecting the Bluetooth Module located in the back under the CD Changer / Nav. I followed these instructions below. I did not have to reset the battery, just power cycled the Bluetooth Module. It all now works as it did before. I think these modules get "locked" up over time and just need a power reset.

Good Luck!

I am out of town right now, but will try this as soon as I can. Thanks, and I will let you know if it works for me, too.

Oh well, it wasn't meant to be so simple for me. I just did the "disconnect TCU & reconnect" trick, without effect. Still no Bluetooth for me.

Anybody got one for sale cheap?

UPDATE: I finally got a chance to take my X5 in to the dealership for this. I figured out that not only was the Bluetooth not working, but also the stereo wasn't working correctly (power on, and subwoofer woofs, but no sound from the stereo). My dealership tells me the main amplifier is dead. They assure me this will explain all the problems. A part is being ordered. I will update when it is all fixed (about a week, probably).

My dealership replaced the stereo amp, and it fixed only the stereo. The Bluetooth module (TCU) was also dead. They were kind enough to suggest that I could find the new TCU much cheaper from a third party and replace it myself. How is that for taking care of the customer, rather than pushing a rip-off? I love these guys!

Anyway, I bought a new TCU from Tom at EAS, and he was great! Sent me exactly the right item, and I saved almost half of what the dealership would have charged. Now, my Bluetooth works fine, my Voice Recognition works, and the phonebook transfers right over. The only thing left is for me to take the car in sometime to get the dealership to re-activate my BMW Assist (some coding I can't do at home).

So, kudos to both EAS and my local guys!

Glad to help.

No dealer visit is necessary, simply get the numbers on the label and give that to your CSR when talking to Assist.

I tried that. I called BMW Assist twice today. They wouldn't do it for me. Said they only give those numbers to the service techs. I called my service guys, and they will take care of it for me next week.
