Exceptionally reliable by European standards. Steering rack knock and corrosion on high-mileage examples are about as bad as it gets.

What To Check Before Buying

  • ✓Check service history — was oil changed regularly?
  • ✓Look for blue/black smoke on startup and under load
  • ✓Listen for rattles, knocking, or turbo whine
  • ✓Test all electrics including windows, AC, and central locking
  • ✓Check for DPF warning light or recent regenerations
  • ✓Inspect for rust underneath and around wheel arches
  • ✓Request a pre-purchase inspection by an independent mechanic

Known Faults

MMT Semi-Automatic Gearbox Actuator Failure

Critical
2005-201150,000–90,000 miles£500–£1500

Models fitted with the Multi-Mode Transmission (MMT) — an automated manual — suffer from severe actuator wear, causing the car to drop into neutral while driving.

Alternator / Smart Charge System Failure

Severe
2005-201170,000–120,000 miles£250–£450

Modern vehicles use smart charging systems to reduce engine load, but the complex regulators on the alternators frequently fail.

Starter Motor Solenoid / Brush Wear

Severe
2005-201170,000–130,000 miles£150–£350

The starter motor wears out internally. This is particularly common on vehicles equipped with Stop/Start systems.

Clutch Slave Cylinder / Concentric Bearing Leak

Severe
2005-201170,000–120,000 miles£400–£800

The concentric slave cylinder (CSC) inside the gearbox bellhousing fails, leaking hydraulic fluid and causing clutch failure.

Suspension Coil Spring Snapping

Severe
2005-201160,000–120,000 miles£150–£300

A very common MOT failure in the UK. Suspension coil springs corrode and snap, usually near the bottom pigtail.

Water Pump Leak and Bearing Failure

Moderate
2005-201160,000–100,000 miles£150–£250

While incredibly reliable, the 1.3 VVT-i engine's most common weak point is the water pump, which develops a leak and noisy bearing.

Sticking Brake Calipers (Slider Pins Seized)

Moderate
2005-201140,000–100,000 miles£80–£150

The floating brake caliper design relies on sliding pins. In the UK climate, salt and water ingress cause these pins to rust and seize solid.

Wheel Bearing Wear and Drone

Moderate
2005-201150,000–110,000 miles£120–£250

Wheel bearing wear is a normal consumable on UK roads, but frequent pothole strikes accelerate the failure rate significantly.

Ignition Coil Pack Failure

Moderate
2005-201150,000–100,000 miles£50–£150

Coil packs break down internally with heat and age, causing severe misfires under load.

Shock Absorber Oil Leak and Failure

Moderate
2005-201170,000–120,000 miles£200–£400

Shock absorbers lose their damping efficiency over time, and eventually blow their seals, leaking hydraulic fluid.

Air Conditioning Condenser Leak (Stone Damage)

Minor
2005-201140,000–120,000 miles£250–£450

The air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.

Front Anti-Roll Bar Drop Link Wear

Minor
2005-201130,000–80,000 miles£60–£120

The front anti-roll bar drop links wear out on heavily potholed UK roads, causing an annoying knocking sound at low speeds.

Electric Window Regulator Cable Failure

Minor
2005-201150,000–120,000 miles£100–£200

The cables inside the electric window regulator mechanism fray and snap, causing the window glass to drop into the door frame.

Engine Thermostat Sticking Open

Minor
2005-201160,000–120,000 miles£100–£250

The engine coolant thermostat fails in the 'open' position. The engine never reaches its optimal operating temperature, killing fuel economy.

12V Battery Degradation and Failure

Minor
2005-201130,000–150,000 miles£80–£250

Lead-acid and AGM batteries have a finite lifespan. Modern cars are highly sensitive to voltage drops, causing bizarre electrical faults before the battery completely dies.
