Engine reliability and common problems:

The BMW N47 engine is sometimes called the worst BMW engine because of problems with the timing chain, which tends to stretch at 100 000 km. In addition, the engine has to be removed from the car to replace the timing chain. The cause of the timing chain problem was reportedly eliminated for engines produced after 2015. Also, the crankshaft damper on this engine tends not to last very long. Cracks between the cylinders tend to appear due to overheating of the engine.
Overall, this engine can last around 220,000 to 370,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
Engine displacement 1995 cm3
Number of cylinders 4
Bore (cylinder diameter) 84 mm
Stroke length (piston move) 90 mm
Compression ratio 16 : 1
Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.

More service info
Timing chain change interval 100,000 km (recommended)

Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur.

Fuel system Common Rail

Common rail fuel injection provides more engine power, is quieter, more environmentally friendly and offers better fuel economy, but is more expensive to maintain and repair.

Often in the first years of production, engines tend to have various constructive problems, so it is recommended to choose a car with this engine from 2010 onwards.

Engine also used on BMW 5 sērija BMW 3 sērija BMW X3 BMW X1 and 3 other models

Generally, the use of an engine in several models and its long production run is an indication of the quality of the engine and the success of its design.
