3.0L V6 (ES9A)
Petrol
Drive the car for at least 30 minutes until fully warm, performing repeated stop-and-go transitions. | Note: The Aisin AM6 6-speed automatic transmission is prone to valve body wear. Watch for harsh downshifts or jerky 2nd-to-3rd gear shifts when the transmission fluid reaches operating temperature.
Toggle through the suspension modes (Sport/Comfort) and drive over varying NZ road surfaces. | Note: The AMVAR electronic active dampening system is highly complex. Warning lights on the dash or a overly harsh ride point to failed electronic dampers which are extremely expensive to source and replace in New Zealand.
Perform a cold start and listen closely to the top of the engine, then accelerate hard on an open road to check for flat spots. | Note: The ES9A V6 utilizes variable valve timing (VVT). Rattle on startup indicates worn VVT gears, while hesitation under load often points to failing ignition coils (historically problematic Sagem units) or blocked catalytic converters.
Operate every single electrical accessory, including the motorized boot lid, electric seats, and dual-zone climate control. | Note: French luxury cars of this era are notorious for multiplex wiring (BSI unit) failures. The motorized boot mechanism is a common failure point, and repairing multiplexed electrical gremlins in NZ requires specialist Peugeot diagnostics (Diagbox).
Routine oil and filter change using high-grade 5W-40 synthetic oil. Inspect the cabin/pollen filter to ensure the HVAC system functions efficiently and doesn't strain the blower motor.
Replace the spark plugs (the rear bank on this transverse V6 is difficult to access, requiring plenum removal). Perform a partial automatic transmission fluid (ATF) drain and fill to preserve the valve body, despite Peugeot's 'sealed-for-life' claim.
Critical timing belt, tensioners, and water pump replacement interval. This is an interference engine; failure will result in catastrophic valve damage. Also, inspect the condition of the auxiliary belt and its tensioner pulleys.
Verify the condition of the dual-battery system (if equipped on earlier models; one main starter battery and one auxiliary service battery in the boot).
Inspect the plastic radiator end tanks and thermostat housing for signs of degradation or coolant weeping due to NZ's UV exposure and thermal cycling.
Ensure only genuine PSA-approved coolant and total Quartz lubricants are used to prevent corrosion in the alloy V6 block.
Regularly clean the sunroof drainage channels to prevent water ingress from damaging the delicate floor-mounted electrical modules.
Monitor the exhaust manifolds and flexible joints; the rear bank manifold is prone to cracking and is exceptionally labor-intensive to replace.
Estimated repair costs if issues arise
Sourcing these electronically controlled shock absorbers from Europe is incredibly costly due to shipping to NZ and low local inventory.
A labor-intensive job due to the tight clearances in the 607 engine bay. Requires specialized locking tools that only European car specialists in NZ will possess.
Required if the transmission begins to slip or shift violently when warm. Includes a new valve body unit, fresh fluid, and adaptation programming.
