Fine, I'll be the guy who brings up fuel pump cooling. The pump does need fuel in and around it to not overheat and fail.
Also, why take a chance on clogging injectors or fuel filters ?
These machines cost 65K++ and you want to ruin them by running on empty?-I don't get it.

Just to wrap up this thread, here is what I've concluded based on your input. When the "Distance to Empty" read out gets to "0" or "--" you have used ~17.5 gallons of your tanks 18.5 capacity. Driving your F10 (or any car) near empty poses a significant risk to the engine. I'm assuming that the engineers at BMW designed the tank to hold an extra gallon to prevent owners from doing significant damage to their engine. Bottom line: Don't let it go to "--", and definitely don't go beyond that. Your car will hate you forever, and so will the poor bastard that you sell it to.

You're conclusion is right, German Roots....
Last week I nearly ran out. I never saw the distance meter get to "---" before... and I was still .4 miles away from the nearest gas station! And it was a hot day and I needed A/C on high... and there was traffic!!!! Real nail biter!!!

Filled the tank and it took ~17.5 gal so I guess I had more room than I thought... Hope it never happens again!!

Shua,
Thanks for sharing! great Photo-Story:thumb up:

I can confirm when the "---" appears you can easily drive at least 1 mile. Made the same experience with my F25 xDrive28i. It was a Thriller !

My highest MPG for a tank has so far has been 30.7 MPG (OBC).
My lowest MPG for a tank so far has been 23.7 MPG (OBC).
My MPG since new is 25.5 MPG.
My longest range on a tank has been 463 miles.
My cumulative OBC MPG error is +0.52% (pump MPG 0.52% higher than OBC MPG).

Resetting the OBC MPG when filling up the tank, I've found a gas pump that's cheating me by about two percent.

I have made 2 miles on "--" on rush hour traffic including waiting on a few traffic lights. When filled it the pump reading was 17.45 gallons. This was not on purpose but the traffic that day was so bad that I spent an hour burning 30 miles range... Very scary though the car did not bark or made any strange noises.

I never let my car go below a quarter tank.
Obvious, mileage depends on engine size, driving condition, even air temp..

Keeping the tyres at the correct pressure saves on fuel bills. I think BMW should install a device that prevents all the fuel from being used up in order to save the fuel pump and injectors. They should make the reserve tank bigger but then devise a locking mechanism to retain 20% of the fuel in the reserve tank. I think that's a brilliant idea if I should say so myself. BMW should employ me as a think-tank (for a fee of course)!

Yeah, and somebody, eventually, will be taking a heart-attack victim to (the) hospital, or will be trying to escape from a mad cannibal serial killer, hit the 20% hard lock on the fuel reserve and their car will stop working. Then, it will be BMW's fault that the heart attack victim died, or the person got killed, chopped up, and eaten by the cannibal serial killer. BMW will be sued for $100,000,000,000,000 and lose. The liquidated company will be sold to VW. VW will use the factories to build more Audis. So, we'll all be driving Audis for the rest of our lives and it will be YOUR FAULT. Can you live with that on your conscious?

Seriously, it looks like they've held back a gallon (3.8 liters) of fuel even after the calculated fuel range has reached zero. They first warn you at sixty miles, again at 30 miles, and then count down your range to zero. If you run a modern BMW dry, it's your own fault.

In the U.S., BMW cannot use the feature that closes the windows and sunroof if the rain detector detects rain. It's because of some possible scenario (involving heart-attack victims, mad cannibal serial killers, et al) could possibly result in BMW getting sued.

LOL at your entire post Autoputzer... love it. They'd deserve to pay the 100,000,000.... in the cannibal scenario, but maybe just a few mil for a lost finger in a closing window...

Interesting Once I was washing my 14 535d and the passenger side window was open and automatically rolled up shut

Maybe yours slipped through. I'm going to experiment this weekend. US E46's had this function disabled. Later E46's also did away with passenger window automatic up.
