Good to know. Just had mine pop up for the second time in 2 months

I had the same problem a month ago and BMW replaced the "TCB and Accumulator"; less than a month later and the same error message popped up again, I'm at the dealership now and they are looking at it again.

I have just had mine repaired for the second time. As stated above leaking through the shark fin.

I just got the "emergency call malfunction" this morning and all my bluetooth calls the other person could not hear me. I called my service adviser and asked if I could clear it on my own and see if it comes back to see if it might be just a "glitch", he said "NO". Explaining that while in Social lockdown I am not going to bring it in, "what if I disconnected the battery - would that clear it"? Again "NO".
I tried anyway......
Deleted my bluetooth connections then removed the battery negative terminal for about 30 min. The "malfunction" is gone, I re-paired my phone and it is working. Maybe the malfunction will return but at least I can rule out a temporary glitch.

GREAT information here - THANKS!!!
(last night was wind driven rain storm so not ruling out a shark fin leak)

It will come back. I suggest taking to your dealer and having it fixed. If you get into an accident SOS call may not function

Lucky you!

Mine called the BMW Emergency Services while I frantically tried to cancel. Wouldn't let me so I had to speak to the representative to tell them the car "went rogue" and called without me asking. Then this notice popped up and I took it in for service where they replaced the antenna because they said it was leaking. Took two days and warranty paid.

[bimmer444]

Any updates?

We had same issue. Interestingly, it is happening in all models with id7 installed. Some owner who have 840d had the same problem after 4 time replacements.
We take this situation very seriously, and it is known that more than 200 vehicles with id7 shipped from 2019 are experiencing this problem.
If this problem occurs after the warranty period, we will have to pay for the module replacement every time, despite the vehicle's chronic defect.

I have this issue currently. Malfunction came on and because of Covid-19 dealer could see car to fix it. In the meantime i had the roof wrapped. Car is at dealership now and they are saying because i had the roof wrapped they will not fix the problem under warranty because they claim its caused by not installing the antenna correctly. smh

Was the antenna removed? If not then there should be no issue. If so, then it is possible it was not resealed properly and water could have leaked into the antennae or telematics control unit.

That exact same scenario has happened to at least 1 or 2 members on this forum. I think the one individual got the shop who wrapped his roof to cover the cost of the repair because of their error in re-installation.

The malfunction occurred before the roof was wrapped.

Sorry, missed that part. However, unfortunately now you are stuck in the position of trying to show that it did in fact occur prior to the roof being wrapped. Maybe freshxdough can confirm if the malfunction would be logged and dated and then you can have them check the date on when the error first logged and then provide the invoice for the wrap showing that it occurred after the date of the first malfunction.

There usually a time stamp showing the fault when it occurred for the first time and the most recent time. The issue with the dealer is that they aren't offering any other solutions. For example, You could say "I'll put down a 1.0 diagnosis on the RO if it comes to the conclusion that the fault lies because of the job performed by the wrap company". That way the dealership isn't out the time the technician took to diagnose the issue.

They do their diagnosis and find that the wrap job wasn't the issue, then you're fine and warranty covers whatever is necessary. If the unfortunate event occurs that it is somehow related then you're out 1.0 and now you get to decide the next course of action.

If the wrap company never removed the antenna cover, then you should have no issue with warranty. It has been known for the sealing at the antenna cover to leak from improper installation from factory. It's also common for the emergency battery in the telematics control unit to fail which can also cause this check control message.

Thanks for the input guys. They offered to charge 2.0 hours of labor to pop the shark fin and let me know if it was due to improper installation or not. I chose not to go this route. It is clear to me that the shop removed the shark fin to wrap the roof properly. I can almost guarantee it will be a "pay us $350 to tell you it isn't covered" situation. If the computer does show a date malfunction first occurred then I'm good. The wrap was done after the malfunction occurred. That i know. I will just take it to a different dealership who is willing to work with me on this. Shitty situation as its my first BMW after selling a Maserati that i wasn't happy with how the dealers operated.

Why not just lower the headliner and inspect the telematics control unit that is mounted under the antennae on the inside of the vehicle? It would help more to also know the fault.

I may do that when i have some time. I have to look at how the headliner comes out. Sucks because the microphone now doesn't work when phone is connected and taking a call.

My module was replaced about a month ago after I got the malfunction that would not clear. The battery was not replaced only swapped into the new module. The malfunction is back and I absolutely HATE the car without a working mic. I have to wait about a month to get a service appointment with a loaner as they tell you its a multi day job. From reading this thread I am assuming my shark fin is leaking - hope to convince dealer to address that.
THANKS!

[joft6]

I had this issue back in my X6, the issue was with a fuse, If you are under warranty they'll take care of it anyways

[richardr773]

I had this issue last year and all they did was replace the small battery that it uses

[Kevin2772]

Ours is going in tuesday for this issue. Have had the car for 3 whole months and already got it.

[london_v]

I had a slightly different but kind of relevant issue last year. As I was driving, the sos number would dial by itself. I'd hear a 'hello what's your emergency' on the other side and I was like WTAF. Strange thing is, I could see a countdown on iDrive but couldn't select no, so it would dial every time.

A few times I had a nice conversation with a nice sounding German lady, in Germany. She knew I was the random dude in the UK who would be unintentionally dialling everyday.

Took it to BMW. They replaced the aerial. Problem came back. They replaced it again with additional water proofing. They kept it for a few days and tested it daily with a jet wash.

Problem was eventually solved.

[Kevin2772]

Apparently ours was the fuse being the issue. Also had them throw on all season tires while there as our summer tires are garbage in the cold/snow.
