Dodgy Fuel Gauge!!

[GilesS3]

I'm sure that someone has had this problem before, but some assistance would be much appreciated!!
I picked up my Griff last week, and when I fill the tank to the brim, the gauge only reads half full!! It then drops to zero, and when I fill up again it only takes £20 - £25 of fuel!!
Is this a common problem??

It sounds like the pointer has been set in the wrong position or possibly moved.

These gauges have to be taken appart to re-calibrate and it can be done at home if VERY carefull.

I'd get your local dealer have it re-calibrated or buy a new one.

Thanks for that!!
You don't think that it might be the sender unit then???
