✓ 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.
High oil consumption (piston rings), can damage the catalyst
usually 70,000–180,000 km · High risk
Signs: Oil level drops between services, low oil warning, blue smoke, later P0420 catalyst code
Fix: Check the level every refuel and do a documented consumption test; shorten oil changes to about 10,000 km; rings or short block if consumption is high, then check the catalyst
€300–4,000
Carbon build-up on intake valves (direct injection)
usually 80,000–160,000 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
Turbo wastegate actuator sticking or failing
usually 60,000–150,000 km · Medium risk
Signs: Engine light, boost fault codes (e.g. P2562/P2563), sudden loss of power or limp mode, rattle from the turbo
Fix: Check the actuator and the wastegate linkage for carbon and free play; adjust or replace the actuator, the turbo only if it is damaged inside
€150–1,500
Oil leak at turbocharger oil lines
usually 40,000–150,000 km · Wear part
Signs: Oil traces around the turbo and its lines, burning smell after a drive
Fix: Replace the line seals and tighten or renew the banjo bolts; the turbo itself is usually fine
€100–400
Misfire codes caused by the dual-mass flywheel (manual, to 2018)
usually 20,000–120,000 km · Medium risk
model years 2015–2018 only
Signs: Engine light with misfire codes P0300-P0304 although plugs, coils and injectors are fine
Fix: Check the date code on the dual-mass flywheel; if older than 'MLE', fit the revised flywheel and clear the codes
€700–1,300
