2002 Ford Mondeo 2.0L Petrol · CK02 NCZ

The 2.0 and 2.2 TDCi Duratorq engines use a high-pressure Delphi common-rail fuel system notorious for failing injectors. Excessive leak-off drops common-rail pressure under load, causing flashing glow plug lights, limp-home mode, and cut-outs. Furthermore, the Delphi high-pressure pump can shed microscopic metallic swarf, circulating through the fuel system and destroying all four injectors. Simultaneously, the dual-mass flywheel (DMF) wears prematurely, creating loud metallic rattles and shedding metallic dust into the starter motor.

The mechanical handbrake mechanism integrated into the rear brake calipers frequently seizes on the Mk3 Mondeo. Road spray, winter salt, and brake dust penetrate past the rubber shaft seals, causing the external operating lever to corrode and stick. When the handbrake is released in the cabin, the return spring fails to pull the caliper lever back to its rest stop, causing the rear brake pads to drag continuously against the disc. This overheats the rear hubs, glazes pads, and causes MOT handbrake imbalance failures.

The 1.8 and 2.0 Duratec HE 16V petrol engines feature variable-geometry plastic swirl flaps inside the intake manifold runners to enhance low-end turbulence. Over time, engine heat and vibration wear the plastic flap bearings loose on their square steel operating spindle. The flaps rattle loudly at idle, and eventually fatigue until the plastic flaps or brass screws detach and are sucked into the combustion chambers, causing catastrophic valve, piston, and cylinder wall destruction.
