What are the most common engine problems in the BMW 2 Series?

I've noticed some unusual noises coming from my BMW 2 Series engine. What are the possible causes and how can I fix them?

If you hear a tapping or knocking sound, it could be a sign of low oil pressure or worn out connecting rod bearings. It's important to get this checked by a mechanic as soon as possible.

Another common issue is a leaking valve cover gasket. This can cause oil to leak onto the engine, resulting in a burning smell and potentially damaging the components.
