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.

 

 

Did you get the new battery coded to the car? It needs to be for full functionality.

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.

Stop/start failure and unrelated electronic problems are typical of a failing battery. A new battery alone will not solve them unless it is coded to the car when fitted. You need to confirm whether that was done before looking for other causes for the faults.

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.

Update

At least you can rule out the battery. It might be worth getting a diagnostic check to see if any fault codes flag up 

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.

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

spelling

Glad you've got sorted 🙂 maybe the MMI needs an update?
