Anyone had their fuel gauge stick showing full ?

I happened to be driving past my usual Shell garage and glanced down at the gauge to see it was showing full but I had driven 150 odd miles so was expecting around 3/4 full....

I am hoping this is not another hefty bill heading my way to repair.....

Anyone had this problem ?

No faults showing with Carista so I will keep an eye on it and see what happens on the next fill, just need to keep an eye on the miles between refill now 

Nope, but mine has on occasion gone to 'empty' and stuck....then re-set itself but with no apparent reason......
