Hi - it's a 2015 90ps petrol Sport Nav which I've had for about a year, and it has a digital fuel gauge. Managed to completely flatten the battery a couple of weeks ago (my fault), and since then the fuel gauge has been showing full, with a predicted range of 400+ miles. Everything else seems ok.

Fitted a new battery in this morning (Yuasa YBX7005), leaving a gap of 10 mins between disconnecting the old and connecting the new - someone told me that might fix it. But it hasn't; did about 140 miles today but tank is still full apparently.

Any suggestions gratefully received

Cheers
John

 

There is a old Tech bulletin out about fuel gauge issues. I would suggest contacting your local dealership.
