Hello all, on friday i put £30 fuel in and the petrol gauge went to just under 3/4 showing a range of 220 miles. Got in the car yesterday and now my gauge says its full with a range of 340 miles after driving 40 miles over the weekend, surely this cant be right? Could it be the sender or maybe the gauge in the dash at fault? Anyone else had similar problems, is it an easy fix? Any help much appreciated. Dave.
