Hi guys, sorry for the first post question. Just wondering if anyone else has had this issue or knows if it is common. Picked up a used Mii today from a main dealer, just over 6000 miles on the clock, showed 3/4 tank on the fuel gauge, filled it up which cost a further £20 (which I thought seemed like a lot?). Done about 70 miles of driving since and hasn't moved at all, still totally full and the navigon has not shown anything that helps on the trip distance, in fact has gone from 375 upto 385. Anyone have any ideas what can be done or if this is a common issue? Thanks in advance!
