Summary
NOISES FROM THE FUEL TANK AT IDLE: All vehicles except the F48 (X1): While driving slowly with low RPM or while idling a faint knocking or fluttering noise can be heard from inside the fuel tank with a low fuel level (approximately less than 2 gallons). The customer may describe this noise as a "helicopter noise" from the rear of the vehicle. F48 (X1) only: While driving slowly with low RPM or while idling a faint knocking or fluttering noise can be heard from inside the fuel tank when the tank is full. The customer may describe this noise as a "helicopter noise" from the rear of the vehicle. CAUSE Pressure fluctuations from the tank ventilation valve will cause the fuel tank filler pipe non-return valve to vibrate. In some cases, the vibration can be heard inside the vehicle.

SITUATION
All vehicles except the F48 (X1):
While driving slowly with low RPM or while idling a faint knocking or fluttering noise can be heard from inside
the fuel tank with a low fuel level (approximately less than 2 gallons). The customer may describe this noise
as a “helicopter noise” from the rear of the vehicle.
F48 (X1) only:
While driving slowly with low RPM or while idling a faint knocking or fluttering noise can be heard from inside
the fuel tank when the tank is full. The customer may describe this noise as a “helicopter noise” from the
rear of the vehicle.
CAUSE
Pressure fluctuations from the tank ventilation valve will cause the fuel tank filler pipe non-return valve to
vibrate. In some cases, the vibration can be heard inside the vehicle.
PROCEDURE
1. Duplicate the customer complaint.
Release the fuel cap while the noise is occurring. Is the noise eliminated by removing the fuel cap?
Yes - Go to step 2.

No - Go to step 3.
2. All vehicles except the F48 (X1):
Check the integration level of the vehicle, if it is not already F020-19-03-540 or higher, then reprogram the
vehicle with ISTA 4.17.1X (released late April 2019) or higher.
F48 (X1) only:
Check the integration level of the vehicle, if it is not already F056-20-03-540 or higher, then reprogram the
vehicle with ISTA 4.23.1X (released early May 2020) or higher.
Always connect a BMW-approved battery charger/power supply (SI B04 23 10) when performing
programming.
3. If the noise continues with the fuel cap removed, the noise may be related to the fuel pump itself. Continue
troubleshooting to isolate the root cause and repair the vehicle as needed.
