Could possibly be my first fault.
 

I have lost the average mpg on my centre screen, it just reads 00, it was reading around the 27 mpg yesterday.
Anyone had this happen to them

No, this has not happened to me.
Can I suggest that you select another app to be displayed on the centre screen and then try the driver performance app again.

tem.

Make sure you have not reset it to zero by mistake. What does your VOC App say or the figure on the bottom right of the driver screen. Are they all zero.

Annoying isn't it! I've had it happen at least twice.

I don't reset my trip mileage so it keeps going up and up so my theory is, it reaches a maximum level, crashes and resets the MPG. First time it did it, it reset from about 57mpg to 0.6mpg in a day.

I thought I might have accidentally set it to zero, but then it would just start recording again, not just stay at zero mpg.
Will try tomorrow, it might cure it's self.

I will give it a go, got to be worth a try.

I'm glad to hear I'm not the only one. I like to keep a tally on my mpg, so I don't reset, that's gone by the board now, but at the moment it's not recording any mpg at all.

I will check on that tomorrow Bernard.
Thanks.

Just had a quick look and VOC is reporting I've done 54.3mpg over the time I've had the car (over 10k miles so far, coming up to 1 year). My spreadsheet of pump attendance says 56.3mpg so not horrifyingly different.

I've found the car computer to be quite accurate, especially compared to some of my previous cars.
