Hey.. good question you posted. I was driving this Xmas from Prague to Barcelona and deciding to skip a few fuel stations on a lonely highway in France went down to about 40Km remaining.. looked not very optimistic until I've come to a station that was some 20Km from the 40Km reserve few minutes ago - remember it was during Xmas so the temperature was around +3 Celsius, but in the place of the fuel station almost freezing because of a hilly terrain. The computer was showing some 25Km fuel left but after I slowed down from 150Km/h to 20Km/h closing to the station via series of roundabouts my 3.0 170kW diesel started choking and refused to start.. just perfectly stopped at the fueling bar..
My only explanation is the temperature drop. It took 5 test starts after refilling the car until it went on again. Pretty scary being stuck in the middle of France during 24th December
So the answer is - NO there is no reserve, be careful!

You might have experienced a bit of foam on the diesel remaining in the tank. As opposed to petrol, does diesel foam. It will put off the sensors and register too high a level remaining.

My car was showing 0 on display by the time i reach at gas station. After filling up gas, everything was smooth until evening and when i started again to go out, it was accelerating more than normal. Even when I'm trying to stop on signals it keep accelerating. Is it something I can revert it normal?

I see this often, when I stop at on an incline. But I never have figured if I lose or gain fuel when stopped on (or traveling) uphill or down.

Driving a diesel (no matter what car) to empty is extremely dangerous for the car.
Condensation and gunk from the fuel tank floats on top of the diesel.
When emptying the tank, the fuel system in the car gets flooded with water and junk (which the fuel filter doesn't always remove!).
This gets into the fuel lines, fuel pump AND into the injectors/engine!

Restarting the car a few times after refilling flushes the system, but there will always be a little bit of water/junk remaining in the system.

So, i have no idea about the reserve, my record on a fill-up is 65 liters, which means there's about 5 liters left in the tank.

haha that's funny, reminds me of back in my teens in my 89 535i we used to almost play a game with the flucuation of the mls left reading, some cars we passed gave us fuel, others took it! That thing could jump either direction 50+ miles in an instant

I will say the e60 is a whole lot better at sustaining a reading then was the case of the 5ers back then

By the time I reached a fuel station, the computer reports 14 miles remaining, the 18.5 gal fuel tank took in 18.1 gal of fuel. I'd say my fuel gauge is pretty accurate. 0.4 gal / 1.5 L for 14 miles / 22.5 km.

you can still drive at 0, maybe up to roughly 30 miles

I never experienced this situation , but I belived for you guys that drive small engine or diesel would be safe to say after the dash warning display saying 0mpg or 0km would be alright to drive a couple more distance until refilling, but how about us that drive v8 or a moster v10 m5 , would you take a chance?

New to the forum so be gentle! I normally go for about 10-20 miles past the "---" (0 miles) before filling up my 520d and get about 69L in the tank. I did manage to get a 3-series 320d to go into "limp-home" mode once as I had so little fuel in. Company cars...
Oh, and I never re-fill until I have got more than 600 miles out of a tank!
