Maybe the easiest tech question ever....

my fuel light died years ago.........I never fixed it and do like a number of others and just reset the trip odometer and know that at 300km coming to a stop on the side of the road is imminent.

A wise man once told me that the fuel warning light only comes on to let you know that the bulb for the fuel warning light is still working.

Actually,
during the years I`ve owned my M900,
my fuel light always have been accurate except once when sender was broken.
Otherwise it has always showed empty at about 13,5L consumed.
Period.

Still, the trip meter is your friend/backup....
