Same engine, other cars
This is the same physical engine (Sigma) sold under different names across brands. Reliability is broadly shared — cross-check these:
Known Issues
Belt-driven; change on schedule.
Fix / Workaround: Belt + water pump on schedule.
Repair cost: €250–€450
Typically appears after: 100,000 km
The 1.4 is slow; the 1.6 is more usable.
Fix / Workaround: Prefer the 1.6.
0The composite thermostat housing cracks and weeps with heat cycles — the classic Duratec/Sigma failure. Cheap part, awkward access; ignore it and you'll cook a head gasket.
Fix / Workaround: Inspect for coolant crust around the housing at every service; replace at first sign — some owners fit it preventively.
Repair cost: €60–€200
Typically appears after: 100,000 km
Ti-VCT versions rattle for a second on cold start as oil pressure fills the VCT units — normal when brief; a rattle that persists warm means worn VCT pulleys or stretched oil intervals.
Fix / Workaround: Brief cold rattle = fine. Persistent rattle = budget VCT pulleys and check oil history.
Repair cost: €250–€600
Mileage Thresholds
After 250,000 km: Reachable with basic maintenance.
After 150,000 km: Thermostat housing usually replaced at least once by now — ask; otherwise these engines just keep going on basic care.
