How to troubleshoot engine noise in a BWM?

I am experiencing unusual engine noise in my BWM. What could be causing it and how can I troubleshoot it?

There are few things that could cause engine noise in a BWM. It could be due to low engine oil, worn out spark plugs or even a faulty engine mount. I recommend checking these things first.

Another common cause of engine noise in BWM is a failing timing chain. This can be a costly repair, so it's important to get it diagnosed by a certified mechanic as soon as possible.
