Reliability verdict

Not enough recent tests to rate this family hatchback. Watch seatbelts/airbags and lights & electrics. Not enough recent MOT data to call this one yet.

What owners report

Reported

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

Clutch and dual-mass flywheel wear on the HDi diesels

Emerging

Owners repeatedly report a slipping or soft clutch pedal on the HDi diesels, sometimes needing replacement under warranty on cars barely run in. Some 1.6 and 2.0 HDi cars have also needed the dual-mass flywheel and hydraulic clutch actuator replaced together, with actuator failures reported around 70,000 miles doing further damage if ignored. A full clutch and DMF job runs roughly £700-£1,200 depending on what else has to come out with it.

1.6 HDi turbo failure from carbon-blocked oil feed

Emerging1.6 HDi diesel only

The 1.6 HDi (shared PSA engine, also in Peugeots, Fords and Volvos of the era) is known for carbon building up in the oil circuit and blocking the small strainer filter that feeds the turbo, starving it of lubrication. Fitting a new turbo without flushing the whole oil circuit just kills the replacement too. It tends to show up from around 90-100k miles as whining, smoke or a warning light, and a proper fix (turbo plus oil pipe and cooler) is £700-£1,500+.

Fuse box (BSI) water ingress causing electrical gremlins

Emerging

Water getting into the underbonnet fuse box connectors corrodes the multipin terminals feeding the ECU, causing intermittent warning lights, central locking that stops working, dashboard glitches and, in bad cases, a dead ECU that needs replacing. It is described as a design weak point on cars from the early-to-mid 2000s rather than a one-off. Repairs range from a clean and reseal of the connectors up to £150-£800 for sensor or ECU replacement if it has been left to corrode.

Timing belt and pulley failure on the HDi diesels

Emerging

This is a cambelt engine, not chain, and owners report cases of the belt or its rubber-cushioned tensioner pulley letting go, which bends valves. On the 2.0 HDi the pulley itself is known to need replacing alongside the belt, not just inspecting, at the recommended 60-70k mile interval. Routine replacement is £400-£700; if it snaps and takes the engine with it, budget £1,500-£3,000+.

Air conditioning and heater faults

Disputed

A recurring but inconsistent complaint: air con blowing weak or warm, or heating that comes and goes, usually down to a refrigerant leak or a failing compressor rather than anything electrical. Some owners get years of trouble-free use, others report repeat visits to sort it, which is why it is a judgement call rather than a universal fault. Regassing or a minor repair is £60-£200, a compressor is more like £400-£800.

Seatbelt pretensioner connector triggering airbag/seatbelt warnings

Partly in the MOT data

This model's measured MOT weak spot is seatbelts and airbags, and there is a real owner-level version of it: a loose or corroded plug at the seatbelt pretensioner (commonly the passenger side) trips a permanent airbag or seatbelt warning light, sometimes clearing itself if you unplug and reseat the connector, sometimes not. It is a connector problem rather than the pretensioner itself failing, but the dash light and the fault code both point at the restraint system, which is exactly what shows up as an MOT advisory or fail on this model. A garage diagnosis and connector repair is typically £50-£150; if the pretensioner unit itself is found faulty it is more like £150-£400 per seat.

What to check on this car

Ranked from this model’s own MOT record, then from what owners report.

Saveable checklist

From this model’s MOT record

The physical checks its own defect data says are worth your time, most telling first.

Underneath, with a torchRuns high on this model Get down and look at the sills, the subframes and the rear suspension mounting points. Flaking scale and bubbling matter; light surface rust does not. On older cars this is the one check that finds the fault that scraps them.Recorded on 8.7% of tests at age 10-15 · class average 0.1%
LeaksRuns high on this model Look at the ground where the car usually stands, then glance under the engine after your test drive. Fresh drips of oil or coolant are the cheapest warning you will ever get about a car.Recorded on 8.6% of tests at age 10-15 · class average 4.8%
Lights and horn walkroundRuns high on this model With a helper, run every light: dipped, main beam, indicators, brake lights including the high-level one, reverse, fog, and the horn. On newer cars a dead LED section can mean replacing the whole lamp unit rather than a bulb.Recorded on 8.5% of tests at age 10-15 · class average 3.5%
Steering playRuns high on this model With the engine running and the car parked, waggle the wheel lightly about the straight-ahead. The wheels should respond almost at once. A dead zone before anything happens means wear in the rack or the track rod ends.Recorded on 7.7% of tests at age 10-15 · class average 1.7%
Rubber boots and gaitersRuns high on this model On full steering lock, look in behind each front wheel at the concertina rubber boots on the driveshafts and steering rack. Splits, or grease flung around the arch, mean dirt is getting into a joint that costs far more than the boot protecting it.Recorded on 6.6% of tests at age 10-15 · class average 1.4%
ExhaustRuns high on this model Listen along the exhaust at cold idle for blowing or chuffing, and give the tailpipe a push to check nothing hangs loose. Small blows only get louder.Recorded on 6.3% of tests at age 10-15 · class average 2.2%
Headlamp lensesRuns high on this model Check for condensation inside the headlamps and for cloudy or yellowed lenses. Both attract MOT trouble, and moisture inside a sealed LED unit generally means a whole new lamp.Recorded on 6.2% of tests at age 10-15 · class average 1.1%

Worth doing on any used car

These judge the seller’s upkeep rather than the model, and they are where the haggling money is.

Tyres, all four Check the tread across the full width of each tyre, inner edge included, and look for cracking and mismatched brands. A set of decent tyres is £500 or more on most cars, which makes this the easiest money to take off a price. If the pressure warning light is on, budget for sensors too.Recorded on 28.1% of tests at age 10-15 · class average 20.9%
Pads and discs Look through the wheel spokes at the brake disc. A pronounced lip on its outer edge, or a rusty and scored face, means discs and pads are due all round, a few hundred pounds on most cars. A haggling point rather than a reason to walk away.Recorded on 5.5% of tests at age 10-15 · class average 11.4%

Because of what owners report

Drawn from the reports above rather than the MOT data. These are the model-specific ones.

Push the clutch pedal and pull away under load, e.g. up a slope. Slipping or a spongy pedal points to clutch or dual-mass flywheel wear.
On a diesel, ask for proof of cambelt (and pulley) replacement at or before 60-70k miles. No paperwork means you don't know if it's due, and a snapped belt can wreck the engine.
On a 1.6 HDi, listen for turbo whine and watch for blue-grey smoke under load. Both suggest the oil feed to the turbo may already be partially blocked with carbon.
Check the dash for a permanent airbag or seatbelt warning light with the engine running. Points to a seatbelt pretensioner connector fault, and will also show up as an MOT issue.
Test all electrics: central locking, windows, dash warning lights, in both dry and just-washed conditions if possible. Intermittent faults after washing suggest water has got into the fuse box connectors.
Run the air con and heater on hot and cold for a few minutes each. Weak or absent airflow either way suggests a refrigerant leak or failing compressor.
Read the full MOT history, not just pass/fail. Repeated advisories on the same seatbelt, brake or suspension item mean it's been left unaddressed.
