    Yup, that's it! I heard exactly the same noise coming from your tank. Mine is just a slightly different tone. Perhaps this is just the way it was designed to sound. My guess is the reason Mini/BMW has a slightly louder pump than most cars, is because of the demand for fuel delivery to feed the engine during boost given that it's a turbocharged engine.

    I want to thank you for taking the time to make the video to compare the pump in the gas tank. It has put my mind at ease knowing that these sounds are normal, unless both of our pumps are about to fail, which I highly doubt.

    Thanks, I really appreciate it.

    Systemlord.

    I shot the underside of my 08 for you to compare. Foolishly I started at the exhaust, but realized my blunder and moved to the tank. There's not a lot to see, but it sounds very similar to me. Hope this helps!

    I can't say that I've heard that from my 08, but I'll take a listen in the garage tonight and report back.
