I recently purchased a BMW M8 and have noticed a knocking noise coming from the engine. It only happens when the engine is cold and seems to go away after it warms up. Is this a cause for concern? What could be causing this issue?
ReplyThe knocking noise you are hearing is most likely due to a phenomenon known as engine knock. This occurs when the fuel in the engine is ignited prematurely, causing a knocking sound.
One possible reason for this could be a low octane rating in the fuel you are using. Make sure to use premium gasoline with an octane rating of 91 or higher for your BMW M8 to avoid engine knock.
Another possibility is that the engine's timing may be off. This can be caused by a malfunctioning timing belt or chain. It's important to have this checked and fixed by a certified mechanic.
