All Known Issues

1.5 / 1.6 TDCi Fuel Injector Failure & Leaking Copper Sealing Washers

SeriousFuel System

The Continental piezo injectors suffer from electronic coil breakdown and erosion of the copper combustion sealing washers, allowing hot combustion blow-by gas ("black death" carbon tar) to bake around the cylinder head.

Est. Repair Cost: £300–£1,100
Warning Signs:

Chuffing steam-train sound from under bonnet when idling, Diesel fuel or exhaust fumes entering cabin through heater vents, Engine cutting into limp mode under load with flashing glow plug light

What to Inspect:
  • Remove plastic engine cover and inspect base of injectors for bubbling black tar residue
  • Listen for rhythmically chuffing injector leak noise

DPF Differential Pressure Sensor Silicone Pipe Heat Degradation

ModerateExhaust & Emissions

The dual rubber/silicone pressure sensor hoses connected to the DPF exhaust pipe degrade and crack from high exhaust temperatures, sending false differential pressure readings to the PCM and blocking DPF regenerations.

Est. Repair Cost: £150–£380
Warning Signs:

"Powertrain Malfunction" amber wrench warning symbol, Engine enters limp-home mode with reduced power, Failed active DPF regenerations causing rapid soot buildup

What to Inspect:
  • Inspect DPF pressure sensor hoses behind the engine bulkhead for heat splitting or melting
  • Scan for DPF differential pressure sensor circuit codes (P2452 / P2453)

Rear Leaf Spring Shackle Bush Corrosion & Clunking Under Payload

ModerateSuspension & Chassis

The rear leaf spring shackle mounting bushes and rubber bump stops deteriorate under continuous payload carriage and salted winter roads, causing rear axle steer and metal-on-metal knocking.

Est. Repair Cost: £200–£450
Warning Signs:

Loud metallic clanging over potholes when driving empty, Squeaking from rear suspension over speed bumps, Uneven ride height side-to-side

What to Inspect:
  • Inspect rear leaf springs for cracked leaves and perished shackle eye rubber bushes
  • Check rear axle u-bolts for tightness and corrosion

Twin Sliding Side Door Lower Guide Roller Wear & Latch Microswitch Sticking

MinorBodywork & Rust

The nylon lower sliding door guide rollers wear flat from grime, causing the heavy side loading doors to drop, scuffing the rear wing paintwork and misaligning the central locking contact pins.

Est. Repair Cost: £120–£300
Warning Signs:

Side sliding door requires forceful slam to latch shut, "Door Ajar" warning lamp stays illuminated on instrument cluster, Scratched paint along lower door sill runner track

What to Inspect:
  • Slide both side doors open and closed, checking for smooth glide and correct door gap alignment when latched
  • Inspect lower nylon rollers for flat spots
