I recently bought a used BMW X6 and noticed that whenever I turn on the engine, there is a loud clicking noise that lasts for a few seconds. It goes away after the engine has been running for a few minutes. Is this something I should be concerned about? What could be causing this noise?
ReplyThe clicking noise you hear is most likely caused by a faulty valve lifter. This is a common issue in BMW X6 models and can be easily fixed by replacing the valve lifter. I would recommend taking it to a mechanic for a proper diagnosis and repair.
It is possible that the clicking noise is coming from the fuel injectors. They can become clogged or dirty over time and make a clicking sound when they are trying to spray fuel. You may want to try using a fuel injector cleaner to see if that helps. If not, it would be best to have a mechanic take a look at it.
Another potential cause could be a loose or worn out serpentine belt. If the belt is loose, it can cause a clicking noise when the engine is started. I would recommend checking the tension of the belt and replacing it if necessary.
