✓ 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.
Injector faults and injection control software (misfire, engine light)
usually 30,000–150,000 km · Medium risk
Signs: Engine or injection warning, 'risk of engine damage' message, misfire or rough running, fuel smell, oil level rising
Fix: Read fault codes and check for an ECU software update first; test the injectors one by one and replace only the faulty ones; change the oil if fuel got into it
€100–1,400
Increased oil consumption
usually 60,000–180,000 km · Medium risk
Signs: Oil level drops between services, low-oil warning, sometimes blue smoke on start
Fix: Rule out external leaks and the crankcase ventilation first, use only approved oil, then do a measured consumption test; rings or engine repair only if confirmed
€100–3,500
Oil leak at the timing chain cover
usually 40,000–150,000 km · Wear part
Signs: Oil traces on the timing side of the engine, oil smell, slowly falling oil level
Fix: Clean and find the exact leak point; reseal the timing cover with the specified sealant
€200–800
Thermostat or thermostat housing fault (coolant leak, slow warm-up)
usually 60,000–150,000 km · Wear part
Signs: Small coolant loss or traces at the housing, engine slow to warm up, temperature gauge erratic
Fix: Pressure-test the cooling system; replace the thermostat housing with seals and bleed the system
€200–600
Carbon build-up on intake valves (rough idle)
usually 80,000–200,000 km · Wear part
Signs: Unstable or hunting idle, hesitation, slight power loss, misfire codes when cold
Fix: Inspect with an endoscope; clean the intake valves (walnut blasting or chemical cleaning)
€250–700
