Citroën C2

The three-door small car that replaced the Saxo, sharing its platform with the C3 and the Peugeot 1007 — so C3 information covers most of the powertrain. What sets the C2 apart diagnostically is the SensoDrive automated manual fitted to a large share of them: a conventional manual gearbox with an electrohydraulic actuator operating the clutch and selecting gears, with its own pump, accumulator, position sensors and control unit. It fails in ways no torque-converter automatic does — a clutch that will not find its bite point sets a position-learning code, and the fix is often a recalibration rather than a part. Beyond that the 1.4 and 1.6 TU engines and the 1.4 HDi are conventional, and the BSI body computer is sensitive to a weak battery.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
