Update- I seem to have fixed this issue by resetting the MMI- so far so good.

Battery is definitely registered correctly and no fault codes yet I still get a beep after a variable time when the clock goes off and doesn't come back on. I don't know if it's an undocumented feature or a fault. Everything else seems to work OK.

Thanks Clifford, I did confirm that the battery needed coding to the car with the garage prior to the work, so I can only assume that they have done this. I'll check this later myself, but I'm fairly certain its been done.

As far as I am aware, National Tyre Service's changed it, but the issue started before I had the battery changed. I was also intermittently losing the stop/start function so I wondered whether some electrical functions were being shut down to conserve battery ? But I was probably wrong as I cannot find this documented anywhere. I just find it odd.

A trivial issue but its starting to niggle. Q2, 1.5 petrol. I thought it might be battery related as car is over 5 years old now, the start/stop kept turning off too, so I changed the battery and it is still happening, the digital clock on the MMI radio screen goes off at the same time as a single 'beep' occurs. No warning lights and I can find no info on this phenomenom. I usually have my phone plugged in with android auto showing google maps, which has its own clock, so it isn't much of an issue for me. I know its trivial but I need to know why its happening. Any ideas appreciated Thanks.
