How do I fix my BWM's engine misfire?

I have a 2008 BWM 3 Series and I have been experiencing an engine misfire recently. I have replaced the spark plugs and coils, but the issue still persists. What else can I do to fix this problem?

Hi Tom, an engine misfire in a BWM can be caused by a variety of issues. One possible cause could be a faulty fuel injector. Have you checked them for any clogs or malfunctions?

Tom, another potential cause for your engine misfire could be a vacuum leak. Check for any cracks or leaks in your BWM's vacuum lines and repair them if necessary.

Hi Tom, have you checked the O2 sensors on your BWM? They can also contribute to engine misfires if they are malfunctioning. Consider replacing them if needed.
