    Transmission could be worn, general wear and tear.
    Check the trans oil level and condition.
    Nothing on these trans can be adjusted and filters are not fitted.
    The 02 sensor fault will not be linked to your trans noise.
    Have the noise checked by your nearest BMW dealer or mechanic found in the "Find a shop" tab at the top of the screen.
    As acceleration noises can be linked to diffs and in some cases misdiagnosis of tyres or bearings.

    Good luck
