Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.
Ranked by probability × repair cost, not by how loudly a failure is discussed. Inherited from the engine, gearbox, chassis and shared components, each written once.
Pre-purchase inspection
The same issue records, reordered into the sequence you can actually check them in: cold start, static, drive, paperwork.
1Cold startYou get one. If the engine is warm when you arrive, come back another day.
2Static checksEngine off, ideally on a lift.
Mileage and servicing
What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.
These sold in enormous numbers, so you can afford to be fussy about condition rather than mileage. A tidy car with a book beats a cheap one every time here.
| Service item | Interval | Cost |
|---|---|---|
| Engine oil and filter Chain and tensioner wear track oil condition. | 15,000 km or annually | €65–100 |
| Steering column check The electric assistance fails and the repair is a large share of the car's value. | annually | €0–60 to inspect |
