Reliability, common problems and owner reviews for the Ford Focus II 1.8 / 2.0 Duratec-HE (petrol). Check this before you buy used.
Widely regarded as the best of the Duratec petrols — this is the Mazda MZR (L-series) shared with the Mazda 3/6, and it's genuinely tough: 350,000 km is on the cards. Importantly it's TIMING-CHAIN driven (the chain is rated for the life of the engine, not a belt to schedule), so there's no expensive belt job lurking. 'Reliable' is well earned; the only niggles are minor and electrical/ancillary — coil packs, thermostat, and the intake's variable runner flaps with age. A safe, strong used petrol.
Known Issues
Chain-driven and normally good for the life of the engine, but it can stretch on neglected, very high-mileage cars; as an interference engine a skipped chain bends valves. A cold-start rattle is the warning.
Fix / Workaround: Keep oil changes regular (clean oil = long chain life); investigate any persistent cold-start rattle.
Repair cost: €400–€900
Typically appears after: 200,000 km
Coil packs fail with age (misfire) and the thermostat can stick, causing slow warm-up or overheating warnings.
Fix / Workaround: Replace failed coils/thermostat as needed.
Repair cost: €40–€250
The variable intake-manifold runner flaps and their actuator can stick with carbon, causing a rough idle or hesitation.
Fix / Workaround: Clean the intake/runner flaps; replace actuator if faulty.
Repair cost: €80–€300
Typically appears after: 150,000 km
Mileage Thresholds
After 150,000 km: Coil/thermostat/intake-runner niggles become more likely.
After 250,000 km: Robust with maintenance — routinely reached; many go far beyond.
Fault Codes to Scan
Pre-Purchase Checklist
- ☐Confirm regular oil-change history (protects the timing chain)
- ☐Rule out a misfire (coils) and a sticking thermostat
- ☐Listen for any cold-start chain rattle on very high-mileage cars
- ☐Good all-round petrol — the durable Duratec
