    Hey all,
    2013 r56 (non S) with 57k miles. Owned it a year with no issues other than replacing ignition coils. Lately it has developed an issue with hesitation and low power when taking off from a stop. It really only seems to be an issue through mid rpms in first gear. Any thoughts?

    Welcome to Motoring Alliance. Not being much of a mechanic I’d check for any engine codes, then check the spark plugs and vacuum leaks.

    Not really sure but if you know your coils and plugs are good it could be a fuel pump or filter problem

    Thanks, I know the coils are good, but haven't checked plugs yet. No codes since the could were replaced. I'll look at plugs and vacuum leaks when I get home.

    Just spit balling here, maybe the HP fuel pump on its way out?

    Is there a way to test the fuel pump?

    You could with a fuel presser gage but I can’t remember if the R56 has a place to attach a gage. Maybe some of our R56 guys will know. If not I can look at my wife’s Mini when I get home this afternoon. Have you changed the fuel filter?

    I'm a bit embarrassed. I thought you had a Cooper S. The regular non turbo Cooper is not a direct injection engine so no HP fuel pump. If you don't have one you should pick up a copy of the Bentley shop manual for the R56.
