HELP! 02 carrera 2 faulty fuel sensor?

[scoobyc]

Just picked my car up from birmingham yesterday and drove all the way north to John o'groats perfectly. Went to start her this morning and i've got a message saying i have a faulty fuel level report to garage. Problem is nearest opc is 350 mile round trip! Has any body had this before and know of any quick fix? eg loose conections etc? Any help greatly appreciated.
