Build my inspection planFrequently asked questions
Is the C1 a safe used buy?
Yes, it shares its platform with the reliable Aygo and is cheap to maintain.
What is the main engine concern?
A rattly timing chain tensioner on higher mileage 1.0 litre cars.
Are parts easy to source?
Very easy, as parts are shared across Citroen, Peugeot and Toyota versions.
Should I stock the 1.0-litre or 1.2-litre engine variants?
The 1.0-litre Toyota-derived chain-driven engine is generally more reliable and popular with first-time buyers due to lower insurance groups. The 1.2-litre PureTech offers better performance but uses a wet timing belt system that requires strict adherence to oil change intervals to prevent belt degradation and oil starvation.
Are the ETG automated manual gearboxes reliable?
The ETG is a single-clutch automated manual that can feel inherently jerky during low-speed manoeuvres. While mechanically robust, the clutch actuators are prone to premature wear if previous owners held the car on the throttle at junctions. Always ensure smooth gear engagements during your forecourt checks.
What are the standard servicing intervals for the Mk2 C1?
Routine servicing must be carried out every 10,000 miles or 12 months, whichever comes first. Sticking to this schedule is crucial to maintain oil quality, particularly for the 1.2-litre engines. Brake fluid requires changing every two years, and engine coolant should be replaced at the four-year mark.
