I have a 2016 BMW 3 Series and I've been noticing a strange rattling noise coming from the engine. It's not constant, but it seems to happen more often when the car is idling. What could be causing this and should I be concerned?
ReplyIt is likely that the rattling noise is due to a loose heat shield on your BMW's exhaust system. It could also be caused by a faulty fuel pump or a worn timing belt. It's important to get it checked out by a mechanic as soon as possible to avoid any further damage to your engine.
I had a similar issue with my BMW 3 Series and it turned out to be a problem with the engine's valve lifters. The good news is that it's a fairly common issue and won't cause any major damage. Your mechanic should be able to fix it without too much trouble.
