Known weak points
- Timing belt interval is short on this engine (often 60,000 km) and is frequently overlooked, risking valve damage
- Fuel pump and injector wear sensitive to fuel quality, causing hard starting and rough running
- EGR valve clogging with soot, causing rough idle and hesitation
- Turbocharger wear from oil starvation if oil change intervals are neglected
- Glow plug failure causing hard cold starts and white smoke
- Flywheel and clutch wear causing vibration at idle and biting point changes
