Fiat 500 dash problem

[Furyblade_Lee]

Hi guys, my daughter has a 2011 Fiat 500 1.2, manual gearbox, and she keeps telling me than the centre circle of her dash ( the bit with the temp and fuel guage ) randomly goes blank but the rest of the outer dash stays illuminated / functional ? But of course, every time I go to check it it works ….. Is this a common fault on these? I can find lots of other faults with the dash but not this particular one? Strange. Any help or advice much appreciated!!
