Mileage estimator/nine beeps

[KennyMacD]

Anyone else having issues with the LBX mileage estimator? Mine is consistently MILES out. Example : today I checked the estimator for the 'next fuel required' before a journey of approx. 125 miles (mostly motorway). The gauage pre-journey said 165 miles to fuel required. But 15 miles from the end of my journey (i.e. after I'd driven about 110 miles) I got a message saying 'insufficient fuel for journey, fuel low'. This has happened on almost every long journey I have made (I've only had the car two months) and is REALLY ****** me off. What's the most economical setting for driving?  I get that the figure is variable depending on city/motorway driving but being 40 miles out seems bizarre. Any intelligence, as ever, appreciated.  

And PLEASE, anyone know how to make that $*#@% 'nine bleeps' stop when I get out of the car? Happens even when I open the rear door to ensure no small children have been left behind!!!!! Also doing my head in!

I imagine the estimator will always err on the side of caution, better warn well before fuel needed than the 1 mile after!

Regarding the beeps, have you looked through the Customization functions in the handbook there are a number linked with the Smart entry & start system.
