Engine reliability and common problems:

The BMW M57 engine is regarded as one of the best German-built power units. Its inline-six layout is praised for reliability, and cars equipped with this engine are often more desirable on the used market. Despite delivering strong performance, the engine remains fuel-efficient and user-friendly.

The Bosch Common Rail system with electromagnetic injectors is highly reliable and long-lasting, provided high-quality fuel and regular maintenance are ensured. At higher mileage, occasional issues may arise, such as leaks at the fuel rail pressure regulator or failure of the main pump, though in some cases, replacing the internal filter solves the problem. Failures are most often linked to poor fuel quality. For engines built before 2003, injectors are repairable—later versions usually require full replacement.

The turbocharger itself is robust and rarely fails. Most boost-related problems stem from cracked vacuum lines or a stuck pressure regulator. A faulty crankcase ventilation system can also cause oil to be forced through the turbo.

Timing chains in the first two engine generations were known to last over 500,000 km. However this, the third generation, received an updated timing setup, may require chain replacement before reaching 300,000 km—a costly repair.

Other recurring issues include coolant leaks from plastic piping, thermostat failure, malfunctioning viscous fan clutch, worn-out crankshaft damper pulleys, or failure of the glow plug control module. Additionally, second-generation engines used a steel exhaust manifold, which was prone to cracking, while the first and third generations came with a more durable cast iron version.
Overall, this engine can last around 270,000 to 450,000 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 2993 cm3
Number of cylinders 6
Bore (cylinder diameter) 84 mm
Stroke length (piston move) 90 mm
Compression ratio 17 : 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 200,000 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.
