I noticed my BMW X5's engine has been making a strange knocking sound lately. It seems to happen only when the car is idling or when I first start it up. What could be causing this and should I be worried?
ReplyThis could be due to a few possible reasons. It could be a sign of any loose components in the engine or a worn out engine mount. It could also indicate an issue with the fuel injectors or a dirty air filter. It is recommended to have a mechanic check your car to diagnose the exact cause and address any necessary repairs.
One possible cause could be low quality fuel. Make sure you are using a high quality fuel that is recommended for your BMW. Also, try using a fuel additive to clean out any deposits in your engine that could be causing the knocking sound.
