So……checked the oil yesterday as per instructions in manual and it was on the min mark. Phoned the dealer who said to bring it in and they would manually check it.
on the drive over it crept up a little. Apparently it was full and the advice was not to rely on the mmi, only take note if it gives you a warning.
Interestingly when I started the car the mmi reported it was full. So, did they either top it up and not tell me, or reset the indicator? I’ll never know but will continue to monitor.
As a side note on leaving the dealer the a/c decided to stop working again!
