I recently noticed that my BMW M9's engine is making a strange knocking noise. What could be causing this and how can I fix it?
ReplyThe knocking sound could be caused by worn out bearings in the engine. It's important to get it checked and fixed as soon as possible to avoid further damage.
It could also be due to low oil levels or dirty oil. Make sure to check and change your oil regularly to avoid any engine issues.
Another possibility is that the knocking sound is coming from the fuel injectors. This can be solved by getting them cleaned or replaced.
