2.4 D5 5-cylinder 212bhp2008–2017DieselAutomaticSUV14 known faults

The 5-cylinder D5 is a legendary engine, but the auxiliary belt tensioner can fail, throwing the belt into the timing belt and destroying the engine.

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

Auxiliary Belt Tensioner Failure (Engine Destruction)

Critical
2008-201250,000–90,000 miles£150–£2500

A catastrophic design flaw on the 5-cylinder D5 engine. The auxiliary (alternator) belt tensioner fails, snapping the aux belt. The debris gets sucked into the timing belt, destroying the engine.

Alternator / Smart Charge System Failure

Severe
2008-201770,000–120,000 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
2008-201770,000–130,000 miles£150–£350

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

Automatic Gearbox Valve Body / Mechatronic Solenoids

Severe
2008-201780,000–140,000 miles£800–£1500

The solenoids inside the automatic transmission valve body get clogged with clutch material, causing harsh, thumping gear changes.

Suspension Coil Spring Snapping

Severe
2008-201760,000–120,000 miles£150–£300

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

Sticking Brake Calipers (Slider Pins Seized)

Moderate
2008-201740,000–100,000 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
2008-201750,000–110,000 miles£120–£250

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

Glow Plug Failure / Snapping in Head

Moderate
2008-201760,000–110,000 miles£100–£300

Diesel glow plugs burn out over time causing cold starting issues. The major problem is they often snap in the cylinder head when mechanics try to remove them.

Shock Absorber Oil Leak and Failure

Moderate
2008-201770,000–120,000 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
2008-201740,000–120,000 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
2008-201730,000–80,000 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
2008-201750,000–120,000 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
2008-201760,000–120,000 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
2008-201730,000–150,000 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.
