I recently purchased a BMW 7 Series and noticed that my engine is making a loud knocking noise when I accelerate. I'm worried that this might be a sign of a more serious issue. Has anyone experienced this before? What could be causing this and how can I fix it?
ReplyHi Jane, I am a car mechanic and have worked on many BMW 7 Series engines. A loud knocking noise is definitely not normal and could indicate a potential engine problem. I recommend bringing your car to a trusted mechanic as soon as possible to diagnose and fix the issue.
