Will the engine stop when "range" drops to zero?
 

I have a faulty fuel level sensor, and the "range" keep dropping to a single digit. There is plenty of gas in the fuel tank.
I wonder whether I would have problem starting the engine or the engine will stop running amid a journey when the "Range" drops to zero?
any relevant info is appreciated.

No.

The range is a computer calculation based on driving habits and has no barring, IMO, on the actual fuel lines/pump/injectors/timing/etc.....

I have driven 20 miles pass the range before and nothing happen, but you may not be that lucky :)

The "range" shows "8km", I continue to drive it just now, the counter reduces to 7,6,5...1, eventually to "----", no problem at all.
I stop the X for an hour for shopping, restart the car, guess what?! The fuel warning light is off, "range" shows "648km"!! Everything seems to be back to normal.

Wierd....

I have found the Range indicator to be very accurate and when it drops to zero or nothing you're pretty much down to less than a gallon of fuel or maybe running on what's left on the fuel lines.

Why would you even want to take that chance? I would just fill up at the earliest opportunity :)

Play Fuel Light Bingo. You'll realize that the gas gauge and computer range estimate don't accurately reflect actual level of fuel. (Just try not to lose this game)

I've driven a few miles on "------" before, but it's not a habbit... On my old 5 Series sedan, when it said "0", it meant it! I ran out of gas one time in that car, and made sure I never got down that low ever again.

Some of you are mis-reading his post. There is something wrong with his gauge, he is not intentionally doing this. Read post #4.

I've lost 3 times this year!!!!

I must have a bad sending unit. My gauge will get to just below 1/4-tank and then stop, never turning on the light. Wife forgot about this while on a trip and ended up walking the expressway (luckily she stalled right under a bridge that had gas stations). The last stall I had was last week when I had forgotten that I had been idling quite a bit since the last fill-up, so my mileage did not accurately reflect how much gas I had used (had been filling up around 350 miles to be safe).

Wish someone could tell me if the fix is a DIY - most people seemed to have taken this one in to BMW to get fixed.
