Trip Computer Fault?

[K1w1]

Hello all I own a 2006 Megane Mk2 1.9L DCi Diesel and when the Fuel range on the Trip Computer reaches 65mi remaining it beeps (which is fine), but when the Diesel remaining mileage reaches 63mi..the trip computer zero's out (no numbers at all!) and i have to rely on the needle Is this common as I would thought it would have continued to show more mileage than 63mi remaining? Any help would be greatly appreciated. Thanks

Its standard, I had a 2004 1.5 dci and still have a 2008 1.5 dci, both of these zero'd like yours, had a 62 dci and i think that did the same. You get used to it.
