Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

SensoDrive automated gearbox actuator failure

SensoDrive semi-auto only

The clutchless SensoDrive box (a manual gearbox with two robotic actuators instead of a clutch pedal) is known for actuator failure: violent judder on gearchanges followed by a refusal to select gears and a drop into limp mode. Neither actuator can be repaired, only replaced, and fault codes like clutch position adaptation errors or actuator motor faults turn up regularly on diagnostic checks. It can happen at any mileage once the unit is a few years old, and a replacement actuator runs to a few hundred pounds, more if both need doing.

Electric window failing to work properly

Emerging

Windows that jam, reverse on their own, or stop responding altogether are a persistent complaint, and it is not always a snapped cable. On these cars the window motor has a control module (Temic) bolted to it, and moisture getting into that module causes electrical faults with no obvious mechanical cause. If the motor tries to run and struggles, suspect the regulator or cable; if there is no sound at all, suspect the module. Repair is anywhere from an inexpensive regulator to a full window motor/module assembly.

ABS warning light from corroded wheel-speed sensors

Emerging

An ABS light that comes on intermittently, especially in wet weather, is usually a wheel-speed sensor or its wiring corroding rather than a failed ABS pump or module. Owners report it clearing itself after cleaning the sensor and connector, only for it to return a few months later. It is not usually a big bill on its own, a sensor and some contact cleaner, but repeated corrosion in the same spot points to a loom that needs proper repair rather than a quick fix.

Oil seeping from the head gasket or cam seal

Partly in the MOT data

Owners and specialists both flag the petrol TU-engine head gasket and camshaft oil seal as slow, hard-to-pin-down oil leak points, sometimes described as an oil leak nobody can find until the car is up on a ramp. This lines up with the measured MOT signature for this class, where emissions and leak-related items are the standout fault category for superminis of this age, and a weeping gasket is exactly the kind of leak that eventually shows as an advisory or fail. A camshaft seal is a modest job, a head gasket is more, typically a few hundred pounds either way depending on labour access.

Heater blower motor resistor packing up

Disputed

A common minor gripe: the heater fan only works on one speed (usually full blast) or stops altogether, traced to the blower resistor pack under the dash. Owners disagree on the cause, some blame debris and leaf litter getting drawn in and overheating the resistor, others just call it a wear part. Either way it is a cheap DIY-friendly fix, a resistor pack rather than a new blower motor.

Early recalls: suspension, ABS and parking brake

Confirmed pattern

The C2 was subject to a handful of official safety recalls in its first UK years: front suspension wishbone mounting bolts under-torqued (2008), an ABS control fault triggered by low battery voltage (2006), and a parking brake cable manufacturing defect (2009). These are old news on any car still on the road now, but worth checking the work was actually carried out, since an unfixed recall from a private seller is a real safety issue rather than folklore.

Viewing one? Ask this

Built from the two sections above.

On a SensoDrive (clutchless) car, pull away and change gear a few times, gently and then briskly. Judder, a thump on gearchange, or a refusal to select a gear points to a failing actuator.
Try every window up and down twice, listening for the motor. No sound at all suggests an electrical/module fault; a struggling motor with a slow window points to the regulator.
Check the dash for an ABS light after a few minutes' driving, ideally after the car has sat in the wet. An ABS light that comes and goes usually means a corroding wheel-speed sensor or loom.
Look underneath at the cylinder head and where the gearbox meets the engine for oil staining. A greasy film that has picked up road dirt is a slow head gasket or seal leak, not always visible on a quick glance.
Run the heater fan through its speed settings. Only working on one speed, or not at all, means the blower resistor needs replacing.
Ask for proof any recall work was done, or check the VIN on the DVSA recall checker. An outstanding suspension or parking brake recall is a safety issue, not just a haggling point.
Read the full MOT history for advisories on leaks or emissions repeated year after year. A recurring leak advisory that never gets fixed is the real-world version of the gasket and seal issues above.
