✓ 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 or high-pressure pump faults: hard starting, smoke
usually 100,000–250,000 km · Medium risk
Signs: Hard or no starting (often when warm), uneven running, smoke, injector or fuel-pressure fault codes
Fix: Read the injector corrections and do a return-flow test; replace the faulty injectors or the pump control valve / pump; change the fuel filter on time and avoid running the tank empty
€300–1,300
Turbocharger wear or failure
usually 100,000–250,000 km · High risk
Signs: Whistling, loss of power, blue or grey smoke, oil in the intake pipes
Fix: Replace or recondition the turbo, and check the oil feed and return pipes and the oil level; keep oil changes on time
€500–1,200
Crankshaft pulley (damper) rubber breaks up
usually 70,000–160,000 km · Medium risk
Signs: Rattle or knock at idle from the belt side, wobbling pulley, auxiliary belt slips or jumps off
Fix: Replace the crankshaft pulley with a quality part and fit a new auxiliary belt; a loose belt can damage the timing belt
€100–300
EGR valve sooting or sticking
usually 80,000–200,000 km · Medium risk
Signs: Power loss or limp mode, jerking, black smoke, EGR fault codes; mostly with city driving
Fix: Clean or replace the EGR valve; on older engines also check the vacuum solenoid and hoses
€100–450
DPF clogging (Euro 5 68 hp with DPF, to 2013)
usually 60,000–180,000 km · Medium risk
model years 2010–2013 only
Signs: DPF warning, loss of power or limp mode, usually after mostly short trips
Fix: Forced regeneration with a diagnostic tool and a longer drive; check the pressure sensor and software; clean or replace the DPF if it is full
€100–1,200
Oil consumption at higher mileage (breather membrane, wear)
usually 120,000–250,000 km · Wear part
Signs: Oil level drops between services, oily intake, sometimes blue smoke
Fix: Check the turbo first, then replace the valve cover with the built-in breather membrane; a compression test shows if the rings are worn
€100–1,500
