I recently purchased a used BMW 5 Series and I noticed that it is making loud, high-pitched noises when I accelerate. I'm not sure what is causing it or if it's something I should be concerned about. Can someone please explain why this is happening and if there is anything I can do to fix it?
ReplyIt's possible that the noise is coming from a worn or damaged belt in the engine. I would recommend taking your car to a certified BMW mechanic for an inspection and possible belt replacement.
Another potential cause could be a loose or misaligned exhaust pipe. This can sometimes happen with age or if you've recently driven on rough terrain. I suggest having a mechanic check the exhaust system to see if any adjustments need to be made.
I had a similar issue with my BMW 5 Series and it turned out to be a faulty fan belt tensioner. It's important to have this fixed as soon as possible to avoid any further damage to the engine.
