I just replaced the fuel pump and the fuel pressure regulator on my 2006 e90 330i. Started up fine and runs fine. Can you guys chime in and let me know how many miles your dash reads on the till empty on your dash after a fill up? Anyone know if either the float on the fuel pump or the fuel pressure regular sends the miles till empty for the car? Mine says 210 after the fill up. Seems low and I'm hoping I didn't reinstall something correctly. Thanks in advance.

I'm pretty sure that is simply calculated by the computer based on your driving habits. It's never all that accurate... You can expect more miles on a tank.

Depending on how you drive of course. Try adding some fuel system cleaner in there.

You should run a few tanks of fuel before you start evaluate the BC tank miles calculation.

Did you replace with OEM?

Better way to check it is with the OBC menu. Enter the hidden gauge cluster menu and go to 6.01. It'll tell you how many liters are in the tank, and also give you the resistance in ohms of the raw readings. In fact, you can rock your car back and forth to watch the values move.

Note that if you're at half a tank, it's normal for the left side to read 0. Gas is not consumed from the tank equally from both sides. It's sucked from the left side first, then the right. This ensures that the fuel pump is submerged in fuel and helps with weight distribution.

for me +/- 400 miles on a full tank

Thanks. I decided to run the car for a while and monitor the gauge. I think everything is ok. The mileage kept climbing. It's all the way up to 360 miles till empty and I've driven around 18 miles or so. I think I'm all good.

Better to use something fuely app to compute milage .
The mpg computer is genrally pretty close. I would never
depend on the the digital readout to tell me when to get gas.
