What are the common engine problems in the BMW 5 Series?

I recently purchased a BMW 5 Series, and I'm worried about potential engine issues. Can anyone share common engine problems in this car model? How can I prevent or address them?

One common issue is the timing chain failure in the N47 engine. It is recommended to replace the chain and tensioner every 50,000 miles as a preventative measure.

Another problem is the high-pressure fuel pump in the N55 engine. It is advised to replace it every 60,000 miles to avoid sudden engine shutdown and costly repairs.
