SOS call system failure help

[Billy_Whizzzz]

Have the (seemingly common) sos call system failure on my 2013 X5 40d. They don’t have the satellite box in the rear as the pre LCI models - so the bypass cable isn’t an option. Any thoughts how to solve? Means no phone, Bluetooth etc tho other things work.

Watching as we have the same problem on our X2. Couldn't see the fuel range on a long journey last night and the sat nav was showing minutes remaining rather than miles

Had this on my 2017 5 series. Had to replace the battery inside the car underneath the shark fin.

On F10 gen yes - but my X5 is gen before so not sure
If same

Same problem here (F30 340i), battery is under the shark fin, requires removal of rooflining and I don't trust the dealership to not damage anything in the process (they've always broken something while trying to fix things).

The SOS call system can be coded out, so it will not show a warning - that's my plan, pretty sure it can be done on any of the other models.

Happened in my X5 (F85).
BMW wanted north of £500 to change the (£50) battery under the shark fin. So I coded out the warning using Bimmercode and will sort it properly at some point.

Thank you. Did you have the same issue as I did - No Bluetooth? And now you have Bluetooth?

I've got a 2 series Gran Tourer with the same problem. Lots of headlining has to come out to change the battery every 3-4 years (who designed that?). I was thinking of cutting a panel in the headlining.

How do you code it out? I have Bimmercode and a Veepeak OBD.

I’m assuming you have a late model E70?

You can code it out for the warning but it will not bring the Bluetooth back, sometimes BMs give the warning but everything works as it should and in those cases, you can just code it out.

In your case, some part of the TCU MOST fibre optic loop has failed, either a part or a break in the cabling. So the first step is to find where the fault lies, which mainly consists of unplugging each device in the loop until the Bluetooth regains function. If you have the rear DVD player, that is also part of the loop.

I wouldn’t condone cutting a hole in your headliner to save an hour of work, but it’s your car.

In regards to coding it out, you’ll need NCS Expert.

I had no issues with Bluetooth, just the error message obscuring half the dash.

I used Bimmercode. I think it was instructions from this link:

I'd get an trim specialist to cut a replaceable flap/panel.
It's ~£500 labour charges removing pillar trim and headlining every 3-4 years.
I wish there was a way to just delete the sodding thing.

Thanks. (Apart from 3001 instead of 3301 in Bimmercode) it worked. Result.

Not sure if the same on other cars but on my G30 it says to remove headlining but I was able to access just by unclipping the rear of it enough to get my hand in.

Thanks all. Am thinking of adding in a CarPlay unit/screen which will deal with Bluetooth and coding out SOS
