    Good morning,

    I have a 2011 BMW 328i that has 72,000 miles and it’s been running rough at low speeds, with a bump as it accelerate but runs fine at higher speeds.
    This is an intermittent problem. I have the following codes P22aa, P24aa and P2600.
    Can you provide any suggestions and a self-help guide to replacing the defective component that will most likely fix the existing problem?

    Thanks,

    Pedro Vinas
