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 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 190,000 to 330,000 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.

| 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. |
