BMW SOS call system failure ! emergency battery

Replacing emergency battery for Telematic Communication Box (TCB)
In this episode I will replace the emergency battery used by the TCB module on this beautiful BMW x6 f16 from 2018 , the battery as any battery is consumable and must be replaced at a certain interval, the battery is part of a very important safety system and therefore it is necessary to replace it, the procedure is very simple if you have the necessary information and a little skill. 90% of the cases when this message appears in the on-board instruments is due to the battery but there are chances that the tcb module is defective, they are usually affected by water.

Remove the headliner to replace a battery? Insane! Video content is great, but hard not to get angry at BMW for doing this to it's customers

Avec l'aide de ce tuto très bien fait, j'ai remplacé la batterie 7, 4 volts sur ma X4 2020. Tout n'est pas pareil et il m'a fallu 1 heure pour le faire, mais ça fonctionne très bien. Par précaution j'avais chargé la nouvelle batterie à 8, 2 Volts, et je n'ai pas eu besoin de réinitialiser le défaut. Reste plus qu'a tout remonter. BMW me demandait 420 € pour faire le même travail qui m'a coûté 35 € pour la batterie.

Huge thanks for posting this! I have a 2017 BMW X6 and was getting frustrated because every other video was for different BMW models. This was the first one that actually matched mine, and it helped me fix the emergency call malfunction perfectly. You seriously saved me a lot of time and stress — really appreciate it!

Finally got around to replacing this battery as it was ok during the 'warmer' months of spring\summer, but as the colder months come it's started to report as failed again. It was a fairly easy job to do, most difficult was getting the coat hooks out as it's a fiddly job. Thanks for the guidance on this.

Ah yes…the most beautiful BMW ever made 😌 (aside from the 7 series of course 😝)

I recently successfully repaired the rattle in my F16’s tailgate by inspecting the clips - half were broken - and when I replaced them and realigned the latch everything was fine. The previous technician who worked on my car wasn’t as careful and thorough as you are. Thanks for always working carefully and ensuring the cars are better when you finish working on them.

BMW Fairfax (Virginia, USA) wants to charge me over $1, 200 to replace this. I purchased the battery for <$50 and will be following this video soon. Thanks for saving me $$$$!

After reading another comment, I understand the logic behind the location and accessibility of the battery. My BMW is 5.5 years old and only has 40k miles on it. The dealer charges $900 to replace this. That's an eye watering amount of money for a tiny little battery that only takes 20 minutes to change. In contrast; I had my oil changed, microfilter (cabin) replaced, and new spark plugs, and that only cost $472 and took almost two hours...also at the dealer. I'm having a hard time reconciling the massive disparity between the two.

Update: Ordered the battery online, bought a cheap set of trim tools at the local parts store, and ordered an NT530 from Foxwell and only have $230 wrapped up in all of it. Already received the code scanner and verified it will clear the code. This particular battery doesn't need to be registered to the vehicle the way the engine battery does. Now I'm just waiting on the battery to arrive.

Thank you for your detailed step by step instructions. It made the job incredibly easy.

[Jotdotcom]

Very clear explanation, thank you! I was quoted £430 for this...

BMW - you have got to be kidding. I found this site because I have just started to get an intermittent warning. Started off with replace the battery and then downhill from there. Not any ordinary battery but some special BMW battery. And then not a simple matter of replacing it but you have to dismantle a lot of the interior. For god's sake, the error message even suggests that the battery charge will run out and need to be replaced - so why on earth do BMW put it somewhere so inaccessible.

Helpful vid - I have a BMW 220 Gran Tourer, roof is longer but I managed to replace the battery by just undoing the roof trim from the back rubber and easing it down gently M. Not much room to work with this way and wouldn’t have been able to do it without this vid detailing the release clip and how to lever off the battery cover.
No need to reset any warnings via OBD though they may still be logged but not displaying 👍👍

i appreciate how thorough you are cleaning as you go very admirable

[robertvereb]

Great, so I just have take the car apart, replace the battery, find a 10000 pieces and put it back together. Bravo, BMW!

I had the problem on my X1 F48 2017 model. Assume it’s software have bugs.

Tested to call SOS after shows SOS system failure message, get through perfectly, which proves the system NOT failure. Used voice control coincidentally last week, the fault message disappeared dramatically, and didn’t back till today.

I rarely use voice control before, have tried to disconnect blue tooth device and reconnect from other youtube video, didn’t work well.

Can’t say it’s the solution, but cost nothing and worth a try.

Very nicely done and well explained video! Thank you. It's nice to see a professional show the correct way of repairing and servicing these modern cars. Do you have any video on 2019 X1 brakes? I just did a complete brake job, sensors, fluid etc. won't allow me to reset
the dash brake light.

[matthewgee]

Is there any way the function can just be coded out? I've had the message appear intermittently for the last month. Sometimes it comes on for a week and then just vanishes.

[franksanchez]

Wow. Definitely doable, but not a quick fix. Thanks for sharing.

[moonwalk]

You the best, once again thank you for cleaning the parts you took off

[calibrax]

Great video, but you really should check the error is fixed BEFORE you put back the headlining and all the trim... just to make sure the problem is fixed! Even a new battery can be faulty!

[lakersbaby]

Hello, after you replace the battery, do you have to reset anything or will the error be eliminated on its own? Thanks for the video!
