225 MPG Message Display Playing Up

Hopped into the car this evening after about 5 mins driving I thought something wasn't right took me another 5 mins to realise I had no display above where the picture of the car is where the MPG is normally displayed tried getting something to flash up. Has anyone heard or seen this before on a 225?

thanks

I assume you mean car battery not key card battery

 

I've had no trouble starting, must be very early signs

 

Fair enough it is 5 years old now
