I recently purchased a BMW 4 Series and have noticed a rattling noise coming from the engine. It seems to happen when I accelerate or drive over bumps. What could be causing this noise and how do I fix it?
ReplyThe most common cause of a rattling noise in a BMW 4 Series is a loose heat shield. This can happen due to normal wear and tear or if the car has been driven over rough roads. To fix this issue, you can either tighten the heat shield or have a mechanic do it for you.
Another possible cause of the rattling noise could be a worn out shock absorber. This can happen over time as the car is driven and can result in a bumpy and noisy ride. To fix this issue, you will need to replace the shock absorber.
