2019 Edition One
.... and fun update. It is back Whatever the problem is, replacement of electronic modules seems not to have solved anything, at least permanently. My saga begins ..
In my case, it is yellow triangle and yellow SOS symbol at the bottom of the dash.After that, all is normal, except for the red warning triangle in the upper left and the "SOS Phone" alert icon at the bottom of the Cockpit Display
Did you notice in the repair statement they mention, ‘the fault switched to sporadic’. To me that implies the fix was not truly a fix, not when the issue is now ‘just’ sporadic.
The software is designed to ignore "sporadic" issues because the assumption is that that would be related to issues with cell service, such as brief dead zones within the cell network or driving through a tunnel. This may be what they are referring to. But if the car just sits in the lot with good cell reception , it should not be sporadic. So I do see your point. It depends on how they tested it, i.e. sitting in the lot vs. driving around.Did you notice in the repair statement they mention, ‘the fault switched to sporadic’. To me that implies the fix was not truly a fix, not when the issue is now ‘just’ sporadic.
But they still got sporadic fault indications. That would be concerning for me and would certainly explain why the issue persists.Based on the mileage in and out of the shop, they did not test it at any length. I suspect it was just a scan software to validate, nothing more.
Hmm. My problem is very consistent. To modify my previous description a little, when I very first start the car I get the alert bleep and the red triangle in the upper left and the SOS icon down below. The message says Malfunction/service not available. Then, as the car boots up, I get a second BLEEP and the triangle turns to yellow and the message that you are displaying shows up. Then the message goes away, leaving the yellow triangle and SOS icon, and all is fine. I sure understand your annoyance with the BLEEP happening randomly. My Z4 has an "icy road" alarm that would wake the dead. Sometimes when it goes off, I almost run off the road. The sporadic nature for your car does seem to imply a possible loose connection, or other hardware problem. My problem seems more like a software lock up, especially since I can trace its origin to a Cell/Data Dead Zone. I hope I don't have to go through this every time I drive to the coast!It goes off right now every time I start the car, but at random times. Sometimes it is immediate, sometimes it is a few minutes afterwards ... no sense, no reason, no pattern as far as I can tell. It is annoying like ****, because it scares me driving along in quiet and out of the sudden the bleeping alarm.
In my case, it is yellow triangle and yellow SOS symbol at the bottom of the dash.

Waiting for the update from the dealership when I can get my baby back in. It took the whole 2 days of having it back and now ... in she goes again.

Unless the dealer wants to gamble that replacing one antenna will fix the problem, so they won't incur the costs for replacing both. That would also let them identify which antenna is the problem.Small update: the car went in today and just got it back. It turns out there are two daisy-chained antenna assemblies and the one that was failed, was not replaced the first time around. YaY. Now both are new and I hope the problem goes away for good.
It does beg the question about the service technician training, something that has been debated here at length on many topics. It does seem at times they do not exactly are 100% sure what they are doing. It is hard for me to believe that a trainer tech would miss the fact that there are two assemblies to be checked and validated, unless I am missing here something basic.
Anyway, next 48 hours should be all telling. It will be pretty warm and I noticed the incidence probability was apparently directly related to the ambient temperature (the warmer, the more likely the issue to occur).
