was experiencing mild hesitation when hitting the throttle and when starting up after a full stop. problem was slowly getting worsre. replaced the O2 sensor down on the exhast pipe, prior to the muffler, and that problem is fixed! part cost $50 from Amazon ($254 from BMW) and was a easy swap, although some mild soldering was required...30 min or so.
