Skoda Rapid dashboard fault

Hi all. 

Recently my 2013 Skoda Rapid SE had a fault with the display on the dashboard, the one in the middle of the the speed and rpm gauge. 

(sorry, can't remember what it's called) 

I don't know what caused it, but was hoping by posting here I might be able to guess how to fix it whithout going to a garage.

About a week ago some of the data on the display went rogue. Now the average mpg, distance and driving time are all way out. 

Everything else works but it is annoying. 

Average mpg is stuck on 49.7 

Distance is on 1997.

Driving time is on 69 hours. 

I would like to fix it, since the Average mpg is very helpful to me.  None of my driving is ever so extreme (69 hours, 1997 distance driven? I don't think so... ) so I know it s a fault. 

Would putting VCDS on it work, or perhaps looking at any error codes? 

Thanks.
