Could not replicate sound, however reprogrammed the modules with the latest i step. Seemed to be good for the first 30km but I heard it again after filling up but only very briefly. |

Isn't the REAL fix just to put gas in your tank?
You bought a BMW, but you cannot keep it filled at a reasonable level that doesn't mess up the fuel pump? |

I wonder if it is a malfunctioning fuel tank vent valve in the engine bay. |

Have an appt on Monday at the dealer. Going to mention the TIS with a copy in hand to the service advisor and go from there. Have extended warranty.

It has everything to do with the how the fuel tank is vented. That's the exact language my service foreman used. He said that the software is supposed to change how the system "pulses" the venting to eliminate the noise.

Good luck! Keep us posted. You should be able to get them to do the SIB even without the extended warranty. It's an old and well known issue.

Canadian dealers aren’t as eager as US dealers to follow up on SIBs - goodwill or otherwise. Glad to have printed out the SIB because the service advisor was quick to quote 2 hours labor to update the I-Level. Advised I have extended warranty and to refer to the SIB and any questions should be directed to corporate. The service advisor indicated he would need to phone in for approval and I agreed before leaving. Returned later in the day and the advisor indicated head office approved the update which I was pleased to hear. When I arrived in the morning the service advisor synched the key data which I asked him to print which confirmed I-Level F020-18-03-530 so after the car was washed and keys returned I asked for a repeat and the key data indicted I-Level F020-21-03-545. Listened for the noise on the drive home but nothing heard; however, will keep monitoring just to be safe. Otherwise appreciate this useful thread!

I started this thread because the gas tank noise was completely unacceptable in a car this expensive. It's a FLAW and BMW knows it as the SIB clearly notes the root cause and fix. It's not about whether I'm too lazy to add gas when the tank reaches 1/4. None of my other vehicles have ever had such a disturbing noise. I'm glad others benefit from this thread. I no longer own the car but will reply if people have questions or concerns. |

By way of update - they did an I level update on my car.
Filled up and ran it down to 1/4. Noise still very present, so I shot off another email to the dealer with detailed notes. They thanked me for the detailed notes and they would consult BMW technical. Been a week and I have not heard back. Will follow up soon. I filled it back up for a second time and this time at 1/4 tank the noise was not as bad. The noise seemed to be shorter in length going away sooner rather than just helicoptering constantly. Maybe its the warmer weather or maybe its the software update? Not sure, but will keep monitoring. |

i started noticing the same 'helicopter' noise and glad i found this thread.
but, mine isn't as loud as the vids posted here, and it's mostly audible inside the car. you could hear it better in the rear left passenger area, closer to the center island/console. i just started noticing it, it might have been there before but just didn't realize it. no relation to fuel level, since i've heard it at full tank, and most recently at 75% and 50% level. 2014 f30 328ix 80k km, so no more warranty. "we will need to diagnose it" is prolly what i'll get once i bring it to the shop, and i'm trying to get more info before that. i've captured a sound only vid for now and i'll try to get more and post them on youtube.

so my options are:
1) software flush 2) change fuel pump and since warranty is done, this'll be out of pocket. i guess indy specialized mech is my next best option. what's the long term effect? if it is in fact the fuel pump vent on my car. hopefully it's not something else :| |

I had same knocking noise on my 2017 330xi when fuel tank is half or less, I tried Liqui Moly Fuel System cleaner one bottle and did some highway runs, so far noise is gone, you want to try that.
