What should I do if my BMW Z4's engine is making a knocking sound?

I recently noticed that my BMW Z4's engine is making a knocking sound. What could be causing this and how can I fix it?

First, check your oil level and make sure it is at the recommended level. Low oil can cause knocking sounds in the engine. If the oil level is fine, then it could be an issue with the fuel injectors or spark plugs. You may want to take your car to a mechanic for a diagnostic test to pinpoint the exact cause.

It is important not to ignore this issue as it could lead to further damage to your engine. If you are not comfortable diagnosing and fixing the issue yourself, it is best to take your car to a reputable mechanic or dealership for repairs.

Another possible cause of the knocking sound could be a worn out timing chain or tensioner. This is a more serious issue and requires immediate attention. Ignoring it could result in complete engine failure. Have your car checked by a professional as soon as possible.
