Help needed - Citroen Picasso - fuel leak or faulty guage

[Evo]

Hi,

Would really appreciate somehelp with a problem on the family bus.

The car is a 1.6 petrol Picasso, it has now repeated the same problem twice. The petrol tank is filled up to the top and the digital fuel guage shows all the bars lit. After 100 miles (as normal) the first bar goes out, then it drops from having two bars out to only half a tank in one hit

The trip reading also shows it only has 200 miles to go till empty, where the hell has all my fuel gone. I can't see it being a leak because the bottom half of the guage drops one bar at a time as normal and if it were a fuel leak it would be the same for the whole tank. I've refilled the fuel tank once it has dropped to halfway and it takes 20 pounds which would equate to 25mpg, the car as it usually does displays 42mpg

This would mean it's not much less economical the the TVR, only i cant get the kids in it for the nursey run

The car was involved in a rear end accident which required the car to be put on a jig, new rear axle etc, could this have damaged the sender in the fuel tank?

Thanks in advance.

It's French, it'll be an electrical fault, or a feature of French cars in reality.


Have you checked from fill to fill to see what actually doing

That's the next step, it may be the digital display falls to half way but the trip meter still reads accurately, seems odd that it was fine pre accident and now it's gone a bit hay wire.

The accident could quite likely have bent the sender float and it is sticking.
Take it back and get it fixed as part of the insurance claim.
