Oh..that car..drives us crazy. My 17y/o Fiat car was waaay better.
Anyways, now sometimes fuel indicator beeps showing that fuel tank almost empty, but it's 80% filled!
When we only was driving with 30% of full tank-there were not such problems and now when we filled 40 Litres, burned like 10 it sometimes shows empty. Turn off the car, wait until BSI shutdown and turn on - and it shows ok.

I know that this car measures fuel level by resistance. SO it's ether sensor stupid, or something influences resistance.
Or maybe this is BSI dieing?

DOes anyone had such problems?
