Engine reliability and common problems:
A significant portion of this engine's issues stems from problems with the direct injection system. After 200,000 km, the timing chains often stretch, necessitating a complex and costly replacement process. Another common issue is the loss of seal integrity in the plastic intake manifold. Over time, the plastic drive shafts for the flaps wear out or become clogged with carbon deposits, potentially leading to flap breakage. If flaps enter the engine, it results in major engine repairs. A knocking sound from the intake manifold while the engine is running is an early warning of imminent failure.The engine also has weak points, including the oil separator and ignition coils, which are prone to failure. Fuel injectors are another vulnerable component, with limited durability. To extend their lifespan, it is recommended to refuel only at reliable stations and use fuel additives. Proactive maintenance and high-quality fuel are essential to mitigate these recurring issues.
Overall, this engine can last around 230,000 to 390,000 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 | 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. |
