Review of the most popular 2-liter diesel engine BMW n47 in 2021, sometimes comparing it with the gasoline counterpart from BMW N20 using the example of BMW 520 f10, which was discussed in the previous video. We talk about the design, about replacing the chain on the N47, about swirl flaps, about cracks in the block, sores and problem areas, about the possibility of chip tuning, and also compare what is written on the Internet with real practice at the Garage Racer service station.
