Reliability, common problems and owner reviews for the Citroen C5 2.0 16V (EW10, petrol). Check this before you buy used.
The PSA EW10 2.0 — a genuinely tough, long-lived engine that PSA rated for 300,000+ km and that frequently reaches 350,000–400,000 km on nothing more than regular oil and timing-belt changes. The most durable petrol in the C4. It's belt-driven and interference, so the belt schedule is critical, and the day-to-day niggles are minor: the coil packs aren't its strong point (misfire/rough running), it can weep oil from the cam/crank seals with age and use a little, and worn engine mounts cause vibration. Thirstier and less common, but as close to bulletproof as a 2.0 petrol gets.
Same engine, other cars
This is the same physical engine (6FY) sold under different names across brands. Reliability is broadly shared — cross-check these:
Known Issues
Belt-driven interference design; a snapped belt destroys valves.
Fix / Workaround: Belt + tensioner + water pump every ~100,000 km / 5 yr.
Repair cost: €250–€450
Typically appears after: 100,000 km
Coils aren't this engine's strong point; failure causes misfire and unstable running, worse with fouled plugs on low-octane fuel.
Fix / Workaround: Replace coils/plugs as they fail.
Repair cost: €30–€200
With age it can weep oil from cam/crank seals and use a little oil; perished engine mounts cause vibration at idle.
Fix / Workaround: Reseal as needed; check oil; replace worn mounts.
Repair cost: €50–€400
Typically appears after: 150,000 km
Coil failures, catalytic-converter faults and occasional engine-control glitches.
Fix / Workaround: Replace coils; diagnose cat/ECU faults.
Repair cost: €80–€600
Typically appears after: 120,000 km
Belt-driven; change ~90–100k miles with water pump.
Fix / Workaround: Belt + water pump on schedule.
Repair cost: €300–€550
Typically appears after: 100,000 km
Mileage Thresholds
After 150,000 km: Oil seal weeps, mild oil use and engine-mount vibration become more likely.
After 400,000 km: Famous for extreme longevity with belt + oil care.
