335 owner: missfire under 1/4 full?

E90PC · 05-25-2009, 06:59 PM

Just want to share this info with all the 335 owners! My friend that works at BMW dealership say that 335 has a software problem with the tank under 1/4 full! If the tank is under 1/4 the engine might missfire. BMW is currently working on a new software to solve the problem. So for now all 335 owners should keep the tank over 1/4 full in order to void the chance of missfire.

Thanks for the info! 335i seems to have a lot of problem with the fuel system.

omg @@ ..something i ALWAYS said to you guys...dont let the tank get under 1/4 yet nobody listens...
too much load on these badly designed fuel pump/hpfp and possible fuel starvation....

Does the fuel pump issue also refers to 2009 335xi model?
For give me for the silly question. I'm a nubie in BMW world. My 1stpost in this form....I came from Subie Nation.

yes it does...and i am on Nasioc also (better community/forum

)
i assume you may already know that the subie owner's are smart enough to
not abuse the throttle when low on fuel cuz they MAY get fuel cut/starvation...

Did not know that! See, you learn something new everyday...Thx for the 411

Thanks, I'll try to keep the tank above the quarter mark all the time

.. at least until BMW comes out with a patch software.

bulldog_yyc · 05-27-2009, 11:07 AM

car always felt "slower" when it was the last 1/4 in the tank - hmmm I wonder why it has a problem....

yes!
my engine light came on the 1st month i got the car.
The dealership advised that it was either bad batch of gas, or low fuel.
