Bmw S55 engine. Last oil change done 5k km ago.

I hear a slight tapping noise around 1500 - 2000 rpm at like city driving and low speed driving, nothing at idle or higher rpms. Noise noticable only in cabin. 110 000 km.

The flakes seems to be aluminium since i cant pick them up with a magnet. Could it be rod bearings?

I changed the oil from Original bmw oil and filter to RAVENOL VST 5W-40 and original bmw filter.
