✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Coolant loss from EGR cooler or water pump leak
usually 80,000–180,000 km · Medium risk
Signs: Coolant level keeps dropping, damp traces near the pump or EGR cooler, white smoke or EGR faults, temperature warning
Fix: Pressure-test the cooling system; replace the EGR cooler or the water pump (pump best together with the timing belt)
€200–900
EGR valve sooting or cracked EGR housing
usually 80,000–180,000 km · Medium risk
Signs: EGR fault codes, power loss, higher fuel use, more frequent regenerations
Fix: Check EGR operation in live data; clean or replace the valve
€200–600
DPF clogging or faulty DPF pressure sensor
usually 80,000–200,000 km · Medium risk
Signs: DPF light, frequent or incomplete regenerations, power loss, higher fuel use; mainly with short trips
Fix: Check the differential pressure sensor and hoses first; forced regeneration, cleaning or a new filter
€100–1,500
Oil diluted by regeneration; early 'change oil' warning
usually 20,000–200,000 km · Wear part
Signs: Flashing oil warning or 'change oil' message well before the service, oil level above max; rev limit if ignored
Fix: Change the oil and reset the counter; avoid only short trips so regenerations can finish
€80–150
Turbo failure or sticking variable vanes
usually 120,000–220,000 km · Medium risk
Signs: Loss of boost, hesitant throttle, whistling, smoke, limp mode
Fix: Check boost hoses and the actuator first; replace the turbo if worn (rebuilds are often not worth it)
€300–1,300
