Do you all realize that driving til the tank is that completely empty is actually bad for the fuel pump right? It is cooled off by the fuel in the tank - running it extended periods of time less than 1/4 tank causes the pump to run hotter than it could be and can shorten the life span of the pump...
Miles per tank means nothing, miles per gallon is better...

My mte is usually 375 to 385 but recently it has drop tremendously. Now MTE is 280 to 300 when filled. My gas gauge mark is full but I'm not getting all the gas in my tank. Its only letting me get 14 gallon out of 17gallon. I don't know why it's doing that. Please Help! Thanks!
I always able to fill up to 17 gallon of gas..why it wouldn't let me fill 17 gallon of gas now but only 14. Maybe something have to do with my evap system chacoal canister, fuel inject, or vents is clogged or even something wrong with some selonoids. I don't know. I was hoping someone know.
Also, now that it is winter, your mpg will go down, mostly due to extended warm up times. The range display is based off the AVG MPG so if the mpg goes down, your range will go down as well. You can reset the mpg by holding down the DISP button while the mpg is on the screen. That will probably make your range even lower though because it will then be based off only winter (low) mpg.

So the gas light never comes on? Or are you too scared to drive far enough for it to turn on.
Anyway, your lack of miles per tank of gas is due to weather. Mileage always decreases when it gets colder.

I've never actually heard of, or seen, a malfunctioning fuel rail sender in a 2IS. But they're a relatively common problem in BMWs, as I've ran into the problem in the E46 and E85 models. Usually it's due to Sulfur deposits on the metallic contacts of the fuel sender sensors, resulting in the sensors not registering a fuel level, and creating an erroneous gauge error. I've managed to clear it up by using Techron Concentrate Fuel System cleaner, and has so far been running a bottle every oil change (~10,000 miles).

You can reset it but it won't lose all of the NAV preferences - only some of it but it's easy to put back.
It is also possible that the gas has changed to the winter blend therefore your MPG would be hit because the fuel burns faster as compared to the normal blend. This would be more noticeable at the low speeds than compared to highway speeds.

I'd still go ahead and fill up at least by the time the light comes on, but you're not gonna harm your fuel pump going under 1/4 tank.
Lobuxracer has posted some pics from TIS showing the system in the past if you wanna search on it.

- Seatbelt beep on/off if you did this.
- Speed/Tacho indicator preferences
- May need to roll down all the windows and all the way back up (except for thew newer cars which have built in memory).

I agree. Those MTE estimates vary wildly. If you do all interstate trips, on my LS, and then refill the tank, the MTE might be OVER 430. If I do a whole tank and I never go anywhere and basically go around town, It might be 320 or something. Nothing really changes and your gas milieage will remain constant. That's just the nature of the animal.
