Hi, yes it was. I got the car back yesterday - dealer replaced the 12 V battery and updated the entertainment software to 1896. All appears good and back in love with the car again! Still got a pop on the sound system but the interface definitely seems a little slickerThat's almost certainly low voltage on the 12V battery. Mine did the same at the dealer after having stood still for weeks. A tidal wave of error messages and pinging, unwillingness to start etc.
You can charge it manually - the positive terminal is in the fuse box on the right hand side of the engine bay (your right, when standing in front). Negative terminal is on the frame, towards the top rear of the engine bay.
