Just checking - I haven't used the car for 4 or 5 days. I pulled out of the garage and stopped. About 30 mins later we left and this was displayed for about 300m before it corrected itself and said all functions now working.
I think I've had this once before. No other issues related to it.

To me knowledge both batteries were replaced in 2015.

Does that sound about right?
 
I get the same message after 3 or so days and I have had both batteries replaced 12 months ago. I'd suspect a possible drain if the batteries are good and fully charged.
This recent short spell of cold weather tests the battery on start up quite severely.
Unless you are capable using a fuse tester and know what you are doing might be worth getting an indy to check if you have a drain as well. Door and seat controllers are both suspects for this.
 
My 211 didn't move for 10 days. Got the same message for 3 mins. All back to normal after. Nothing to worry about.
