✓ 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 stretch and tensioner wear
usually 100,000–200,000 km · High risk
Signs: Metallic rattle from the chain side on cold start, crank/cam correlation fault code, engine light
Fix: Measure the crank/cam deviation with a diagnostic tool; replace the chain kit with tensioner and guides before the chain jumps
€800–1,300
Injector faults or leaking injector seals
usually 80,000–200,000 km · Medium risk
Signs: Hard starting, rough or knocking idle when cold, power loss, higher fuel use, sometimes limp mode
Fix: Read per-cylinder correction values and back-leak; repair or replace only the faulty injector and renew its seal
€200–1,200
EGR valve sooting
usually 80,000–180,000 km · Medium risk
Signs: Engine light, rough idle, hesitation, power loss or limp mode; worse with short trips
Fix: Check EGR movement in live data; clean or replace the valve
€200–500
DPF clogging or faulty DPF pressure sensor / hoses
usually 80,000–200,000 km · Medium risk
Signs: DPF light, interrupted or frequent regenerations, limp mode; mainly with short trips
Fix: Check and clean the pressure sensor hoses first, then read soot load; forced regeneration, cleaning or a new filter
€100–1,500
Turbo variable vanes or actuator sticking
usually 100,000–200,000 km · Medium risk
Signs: Boost fault codes, power loss, limp mode, sometimes whistling or smoke
Fix: Check boost control and charge-air hoses for leaks first; free or replace the actuator, replace the turbo only if it is worn
€150–1,300
Glow plugs or glow plug control unit failure
usually 80,000–200,000 km · Wear part
Signs: Hard starting in cold weather, smoke after a cold start, glow plug warning light
Fix: Test the plugs and the control unit; replace faulty parts (seized plugs may need extraction)
€100–400
