All 2 Known Issues
On the 2005-2022 Citroen C1, the C1 shares the Toyota/PSA 1.0-litre platform clutch judder issue. The clutch disc develops hot spots from urban driving and the lightweight flywheel amplifies vibration through the drivetrain on take-off.
Common Symptoms
- Judder on take-off
- Vibration through clutch pedal
- Shudder in first gear
- Inconsistent engagement
How to Fix
Replace the clutch disc and pressure plate. Resurface or replace the flywheel. Check engine mount condition as worn mounts exacerbate the judder sensation.
On the 2005-2022 Citroen C1 1.0L 1KR-FE, the 1.0-litre three-cylinder engine in the C1 is prone to ignition coil failure, causing misfires and rough running. The coil-on-plug design makes individual cylinder misfires easy to diagnose but the coils fail frequently.
Common Symptoms
- Engine misfire
- Rough idle
- Loss of power
- Check engine light
How to Fix
Replace the faulty ignition coil. Consider replacing all three coils simultaneously as they tend to fail in sequence. Replace spark plugs at the same time.
