Battery change stuffed my fuel gauge

[rhinos]

Hey I have a problem with my fuel gauge in my vyII R8. When i turn the car on it reads the right amount of fuel for about 5mins then just shoots up to full and stays there. I know this has only just happened as I changed my battery.. Is there something I need to reset? Or is it the sender? Iam stumped for answers, and its pissing me off! Any ideas guys? Any one else with this problem?

Yeah ive changed my battery before and the gauge started doing weird things, but i put a full tank of fuel in and it reset itself to normal.

Yes , try to disconnect the battery ,with the ign off, then reconnect after 15 secs. turn ign on. hey presto.....

yep I had the exact problem. VY S1. Fuel gauge start normal, then shoots to full after about 30 seconds after starting car.

I fixed mine by disconnecting the battery entirely for about 10 minutes (it resets the computer apparently?).
Anyway 8 mths of dodgy fuel gauge fixed in minutes
