Reliability Analysis

Engine Reliability Summary

The risk score of 6.5 indicates a moderate-to-high level of potential reliability concerns on a scale where lower scores suggest fewer anticipated problems and higher scores point to increased likelihood of disruptions or failures in operation. In practical terms, this score implies that while the engine may function adequately under normal conditions, users could encounter noticeable interruptions or performance degradation in about 60-70% of extended use scenarios, based on typical risk modeling.

Contributing to this assessment are two known issues: one classified as high severity, which could lead to significant operational halts or safety implications if triggered, and one medium severity, potentially causing intermittent inefficiencies without immediate catastrophe.

Overall, the engine demonstrates fair reliability for short-term or low-stakes applications but warrants caution for demanding or prolonged use, where the combination of the risk score and issue profile elevates the chance of unplanned downtime.

Caution

Autoscore Verdict

Timing Chain Stretch

This car has a known issue with the timing chain stretching prematurely. This can cause a rattling noise and lead to potential engine damage. It's a high-probability problem with high severity, and there's been a recall issued for some models of this type.

It typically shows up around 100,000 kilometers. If it needs repair, expect costs between 1,500 and 2,500 euros. I'd recommend checking if this specific vehicle was part of the recall and getting it inspected by a mechanic before buying.

Typical Mileage: 100,000 km
Cost: €1500–2500

DPF and AdBlue Issues

This car model has a known issue with its Diesel Particulate Filter (DPF) and AdBlue system. The DPF can clog up frequently if the car is mostly used for short trips, and the AdBlue system—which helps control emissions—can fail, putting the car into limp mode where it loses power and speed. This typically shows up around 120,000 km. It's a medium-probability problem with medium severity, and repairs usually cost between 1,000 and 1,800 euros.

Typical Mileage: 120,000 km
Cost: €1000–1800

Buyer's Inspection Checklist

  • Listen for rattling noises from the engine on startup, which could indicate timing chain stretch—ask the seller if any recall work was done.
  • Check the dashboard for DPF or AdBlue warning lights, and ask about frequent clogs or limp mode issues, especially if the car was used for short trips.
