4.0L S65 V8
Petrol
Test Drive Task: With the engine at full operating temperature, gently accelerate in a higher gear at low RPM. | Description: Listen for any rhythmic ticking or knocking sounds that could indicate potential rod bearing wear, which is a known characteristic to monitor in the S65 engine.
Check this by: Cycling through all modes of the M-DCT transmission while stationary and during low-speed crawling. | Description: Assess the engagement quality for any harsh jerking or hesitation, as the clutch packs may eventually reach the end of their service life.
While inspecting: Look closely for any fluid residue around the electronic throttle actuators. | Description: These units can become temperamental as they age, often triggering a 'Limp Mode' if the internal gears experience wear.
Test Drive Task: Ensure the steering feels consistent and responsive while navigating winding roads. | Description: Some owners find that the steering rack or associated power steering hoses may develop minor leaks or play as the vehicle clocks up more kilometers.
Consider a full fluid refresh including the differential and transmission to maintain optimal drivetrain health.
A common point for suspension components like control arm bushings and dampers to show signs of age-related fatigue.
The cooling system, particularly the radiator and water pump, should be evaluated for integrity to ensure the V8 runs at its intended temperature.
Prioritize documented proof of oil changes every 7,000–10,000km rather than relying solely on the extended factory service intervals.
Verify the presence of high-quality, 10W-60 synthetic oil, which is essential for the high-revving nature of the S65.
Check the service history for spark plug replacements, typically due every second or third oil service.
Inspect the brake rotors and pads for even wear, especially if the car has seen any track use.
Check that the 'service due' digital readout aligns with the physical receipts provided by the seller.
Estimated repair costs if issues arise
While not a certainty, many enthusiasts choose to perform this as a preventative measure for peace of mind. Future Budget Planning: It is wise to set aside funds for this comprehensive internal engine work if it hasn't been documented previously.
These internal gears can strip over time. Depending on the car's history, you might eventually need to budget for replacing these actuators to ensure the engine runs smoothly.
To keep that sharp M-handling feeling, you may eventually need to budget for refreshing components like bushings, links, and shocks as they wear naturally with age and road conditions.
