What are the signs of a clogged oil filter in a BMW 2 Series, and how does it affect engine health?

During my last oil change, the workshop said the oil filter was very dirty. I’ve also noticed some engine noise and rough idling. What problems can a clogged oil filter cause if not replaced on time in Pakistan’s hot weather?

A clogged oil filter restricts oil flow, which leads to:

Increased engine noise due to poor lubrication.

Rough idling and potential overheating of engine parts.

Accelerated engine wear and possible long-term damage if ignored.

In Pakistan’s hot climate, oil and filters degrade faster. BMW recommends changing the oil and filter every 10,000 to 15,000 km o r once a year, whichever comes first. Using high-quality synthetic oil and filters helps maintain engine health.
