Timing chain change interval | 400,000 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. |
