Known issues, ranked by expected cost
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.

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 are simple enough that a 200,000 km example in good condition is a fine buy. The chassis and the interior wear out before the engine does.
| Service item | Interval | Cost |
|---|---|---|
| Engine oil and filter Chain and tensioner protection. | 15,000 km or annually | €65–100 |
| Brake fluid Routine safety work that budget cars often skip. | every 2 years | €60–90 |
