I noticed that my BMW M7 engine has been making a strange noise lately. It sounds like a rattling or knocking noise. What could be causing this and what should I do?
ReplyYour engine may be experiencing an issue with the timing chain or the valves. It's important to bring your car to a BMW certified mechanic for a diagnostic test and repair.
It's possible that the noise is being caused by a loose component, such as a belt or pulley. Have a technician inspect your engine to identify the source of the noise and make necessary repairs.
If the noise only occurs when the engine is cold, it could be a sign of a worn-out serpentine belt or tensioner. Have a mechanic check these components and replace them if necessary.
