The faults with the highest risk: timing chain wear (150,000–250,000 km, €3,000–5,000); timing chain tensioner (pre-2013) (80,000–160,000 km, €1,000–2,000); DCT mechatronic / solenoids (120,000–220,000 km, €800–2,000); EGR / DPF (120,000–200,000 km, €400–1,800). The full list by engine is on this page.
Before you buy, ask an authorised dealer to check by VIN whether the car has any open recalls. If the engine has a timing belt, ask for the invoice for its replacement: with no proof, assume it has not been done. On the test drive, watch for these signs: rattle at rear of engine; rattle on start. The full checklist is in the guide to buying a used car.
