Why does the petrol pump keep cutting out when i try to fill up my X5?—by 5446
Best Answer —by Mike B
Don’t pull the valve handle full open right from the start. Start the fuel flow slowly.Whats happening is, when the fuel flow starts at full volume immediately, you’re creating a “dam” of fuel part way down the filler pipe into the tank. As fumes need to escape, they push that fuel dam back up the filler pipe to the fuel nozzle, causing the sensor in the nozzle to indicate a full tank and shut off the fuel flow.
Starting slow allows a flow of fuel down the lower side of the filler pipe and fumes along the upper side of the pipe to start. Once established, you can increase the volume of fuel flow to full.
