Ok, the car's done this before. I mean the guage stayed on empty after filling the tank. A week ago, I switched on the ignition half way through filling up and the guage moved to half. Switched off the ignition again but after filling the tank completely, it was still showing only half full.
Drove about 250km and the needle showed almost empty. (Now how can the needle move regularly towards empty while it is still over half full?) So I filled up, but only about 30 liters went in and the needle is still stuck on empty. The fuel low LED has now been on for the last 200km and the needle is still on empty but fuel consumption computer shows 8 liters per 100km which is excellent. If I could just get the needle to show what I've got in the tank. Can anyone explain how this works?
PS: My brother drives a C180 merc and says that his car sometimes still shows empty just after filling the tank too. Does the C class merc have the same crap system for measuring fuel?
