I have been chasing cylinder misfire for a while now. After getting error code P301 (29CD) changed coil pack (one was worn out) and spark plugs.
Did not solve the issue. Next morning started up car. Got misfire on cylinder one and four with codes P300, P301, P304 and more specifically code P2ED2 and P29D0 (guessing they are just BMW specific codes).
However, after two minutes when I restart the engine EML goes off and car runs fine with a engine vibration.
Could it be vacuum issues or injector?
have the same problem?
