Recently bought an auction vehicle. Still hasn't been delivered. My DA did not see the video that was attached to the vehicles page. I just opened it up to see its a 10 sec video of the engine running. The engine is making an awful knock and possibly a misfire. I have no mechanical experience w/ BMW's so reaching out here to see if this is likely an engine replacement scenario. 2013 4.4L 750i w/ 106k on the clock.
