Why does my BMW X8 make a knocking noise when I accelerate?

I recently noticed that my BMW X8 makes a knocking noise whenever I accelerate. It doesn't happen all the time, but it's becoming more frequent. What could be causing this and what can I do to fix it?

The most likely cause of the knocking noise is a worn out engine mount. This is a common issue in BMWs and can be easily fixed by replacing the mount.

Another possible cause could be a loose or damaged exhaust system. Check for any loose or missing parts and have them replaced if necessary.

If you notice the knocking noise is more pronounced when turning, it could be a sign of worn out suspension components. Have a mechanic inspect your suspension and replace any worn parts.
