It's been some months since I made reports on this thread and thought to share an update. I've just come back from smc Woking seat and spent 3 hours on software updates. The dealer was not at all surprised by the issue. Regular thing.
They've applied the manufacturers code but commented they've applied a fix release they specifically use. In the 23 mile drive home there was no pops or bangs from the centre speaker. There was plenty on the way there. Noticed the car voice has gone to male and the air conditioning label has changed to say clima now. Not explored fully but it does perform quicker. I'll reply back in a month after some usage and see if the sos appears. It was doing it all the time prior to the update.
A temp work around I used was to press the sos button for at 2 minutes. The sos call will start 30 seconds later. Cancel and the sos goes away until the next time.
