Petrol
Drive over speed bumps and listen for knocking or clicking from the front wheels. | Note: Front suspension pivot bearings are a notorious weak point on the 407; failure leads to steering play and costly repairs.
Let the car reach operating temperature and check the center multi-function display for fading. | Note: The LCD screens in early 407s are prone to pixelation and fading when hot, often requiring a total unit replacement.
Check the power steering fluid reservoir for foaming or 'bubbles' after a short drive. | Note: The high-pressure power steering pipes can fail or air-lock, causing heavy steering or a whining pump.
Operate the heater/AC controls and check for dual-zone temperature consistency. | Note: Internal HVAC heater box flaps often snap, requiring a dash-out job to repair which exceeds the value of many older units.
Standard oil and filter change; inspect cabin filter and check for early sign of power steering fluid leaks.
Major service including spark plugs, brake fluid flush, and thorough inspection of the front pivot bearings and lower arm bushes.
Critical timing belt and water pump replacement; the EW7J4 engine is interference-type and failure is catastrophic.
Timing belt and tensioner replacement (every 100,000km or 10 years).
Pivot bearing lubrication and play check.
Coolant system pressure test (plastic housings are prone to cracking).
Diagnostic scan for CAN-bus 'ghost' faults or depollution errors.
Brake disc thickness check (407s are heavy on front rotors).
Estimated repair costs if issues arise
High wear item on NZ roads; labor intensive to press out.
Preventative necessity to avoid engine replacement.
Common failure that disables cruise control and safety systems.
