✓ 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.
Timing chain tensioner / chain stretch: rattle on cold start
usually 40,000–150,000 km · High risk
Signs: Rattle for a few seconds after a cold start, later camshaft timing fault codes
Fix: Check chain stretch and the tensioner revision; replace chain, tensioner and guides with the updated parts before the chain can skip
€500–1,500
Coolant leaks (water pump area) and overheating
usually 40,000–160,000 km · Medium risk
Signs: Coolant level drops, traces of coolant near the water pump, temperature rising in traffic or summer
Fix: Pressure-test the cooling system; replace the water pump or leaking seals, check thermostats and the radiator; do not keep driving if it overheats
€150–700
Carbon build-up on intake valves (direct injection)
usually 60,000–150,000 km · Medium risk
Signs: Rough idle, hesitation, misfire when cold, slight loss of power
Fix: Inspect the valves with a scope and clean them (walnut blasting); sprays give little result
€300–700
Spark plugs fail early: misfire, rough running
usually 30,000–120,000 km · Medium risk
Signs: Misfire, shaking at idle, flashing engine light, hard starting
Fix: Replace all plugs with the specified type and gap, check the coil on the misfiring cylinder, do not stretch the plug interval
€80–300
Injector fouling or early injector wear
usually 60,000–150,000 km · Medium risk
Signs: Loss of power, uneven running, misfire codes, engine light
Fix: Check injector balance and fuel trims; clean or replace the faulty injector with new seals
€200–900
