Ive done a forum search but havnt really found an answer to the prob, can anyone give me insight on this please?

Probably a faulty sender unit. Change the screen mode to 'KMs til empty' and monitor that aswell.

i find when i fill mine, if its near a quarter full, when i start the car after filling, it will show full then go back to where it was, stay there for a few mins, then work its way back up, it only happens when i fill up though. could this be a related problem?

Well i read somewhere, i cant remember where. i gotta find out that the fuel gauge only gives you an average mean not actual values because as you drive the fuel churns a lot in the tank which can cause the readings to go out of wack.

But then again, why is it it doesn;t happen to other cars? I dont know but i get a similar problem on my VT and every other VT i have looked at does that too. It must be something to do with the software maybe.

VT fuel guages are crap..Had mine fixed once & now stuffed again..
There should have been a recall on these I recon..
Like for goodness sake they can get the fuel gauge to work on an EH but not on a VT for fuks sake

ok guys i had a look at it yesterday when i took it for a drive and the gauge said half a tank , and the fuel light was on, how can that be? isnt the fuel light onli supposed to be on when there is 10L left? she said the light comes on sometimes at 3/4 tank also, the fuel gauge seems accurate cos we compared with how many k's she does to what the gauge says, its just the light coming on that has us confused??? any ideas? Much appreciated

I replaced my vx sender unit last month - this is a really common fault. New sender cost around $100 and you have to pull the tank out. seems a crap solution but after trying to fix the old sender a while back (lasted only a few weeks) I'd say that purchasing the new sender and dropping the tank, or paying someone to do it is the only fix that's going to work.

If you have a multimeter you can test the sender on ohms - disconnect the harness and measure the impedance - should be between 240 ohms (full) - 40ohms (empty) any other readings or if it jumps around like crazy then the sender is faulty.

If you do this measurement tho make sure you disconnect the harness - you dont want to attach the meter to the instrument computer side and risk harming that. One harness you can get to (with less dificulty than others) is in under the rear axle. Gregorys will tell you more.

If you have a Berlina/Calais then one work around is to reset the trip distance every time you fill up and then use the "fuel used" display to show how much you've used (and therefore how much you've got left).
