So Engineering Mode and Self Test....
Petrol gauge as you see doesn't hit maximum. When I fill to the brim it shows just over 75% full, and when low it goes way below the red E line.
While powered up I've moved the needle and now...
Will fill up car on next pay but could that be it one wonders...
Oh and only thing is when I switch ignition on it does this, I didn't think there was any movement with ignition coming on...
I'll see where the needle goes now when I fill and might even leave the screen off so I can get the needle bang on.
