2.2L I4 (EW12J4)
Petrol
Execute full-lock turns at low speed and listen for clicking or metallic clunks. | Note: The 407 uses a unique double-wishbone front suspension; the lower swivel hubs and ball joints are notorious for premature wear and are expensive to replace in NZ.
Cycle the automatic transmission (if equipped) through all gears, ensuring it reaches operating temperature. | Note: The AL4/AM6 gearboxes frequently suffer from solenoid failure, leading to 'Gearbox Fault' warnings and harsh downshifts from 3rd to 2nd gear.
Check the central multi-function display after the cabin has warmed up for 15-20 minutes. | Note: The LCD screens are prone to 'fading' or turning completely black when hot, making the radio and climate control settings impossible to read.
Operate the dual-zone climate control, switching from full cold to full heat on both sides. | Note: Air conditioning mixer flaps are a common failure point; if one side stays hot while the other is cold, it requires a dashboard-out repair.
Standard synthetic oil change and pollen filter replacement; check power steering fluid for foaming (common aeration issue).
Major service including spark plugs and brake fluid flush. Inspect timing belt for cracks even if it hasn't reached the age limit.
Critical timing belt and water pump replacement window. Inspect all cooling system plastic connectors for brittleness due to NZ heat cycles.
Verify Timing Belt/Water Pump replacement history (intervals are 4 years or 100,000km).
Inspect the high-pressure power steering hose for leaks or weeping near the pump.
Check lower control arm bushes and swivel hub bearings for play.
Scan for 'Depollution System Fault' codes using a Lexia/PP2000 diagnostic tool.
Clean the throttle body and inspect the breather hoses for oil sludge buildup.
Estimated repair costs if issues arise
Essential preventative maintenance to avoid catastrophic engine failure; price includes labor.
Common WOF failure item. Specialist tools are often required for removal.
Extremely labor-intensive as the entire dashboard must be removed to access the heater box.
Cost for a new 'updated' part that resists heat-fade better than the original factory unit.
