I recently noticed a loud knocking noise coming from the engine of my BMW 1 Series. It only happens when the car is idling and the noise gets louder when I accelerate. What could be causing this and what should I do to fix it?
ReplyThe loud knocking noise could be due to a worn or damaged engine bearing. It is important to get this fixed as soon as possible to prevent further damage to your engine.
Another possible cause could be a loose serpentine belt or faulty tensioner. These can be easily fixed by a qualified mechanic.
I had a similar issue with my BMW 1 Series and it turned out to be a cracked engine mount. I would recommend getting this checked out by a professional to avoid any potential safety hazards.
