4.0L V8 Twin Turbo - C63 S AMG
Petrol
While accelerating steadily in Comfort mode, check for any hesitation or jarring gear shifts, as the MCT (Multi-Clutch Transmission) requires smooth adaptation and early models may benefit from software updates.
Check this by turning the steering wheel to full lock at low speeds; listen for any 'scrubbing' or clicking noises, which can occur on these performance models due to the aggressive geometry of the front axle.
Before starting the engine cold, check for any rattle or ticking noise from the engine bay upon initial startup, as this can be an early indicator of timing chain tensioner wear.
While driving on an uneven road, listen closely for any knocking or metallic clunks from the suspension, as the stiff AMG-specific bushings can wear over time on NZ roads.
Time to inspect brake rotor thickness and pad life, as these high-performance items often require replacement around this mark depending on driving style.
Consider having the transmission fluid and filter changed to maintain shifting quality and longevity of the MCT unit.
Recommended inspection of the turbo cooling system components and secondary water pump for any signs of weeping or thermal fatigue.
Prioritise regular engine oil changes every 10,000km or annually, regardless of what the digital service indicator suggests.
Keep a close eye on your tyre pressures, as the high-torque output is sensitive to the grip levels provided by the specific Mercedes-AMG MO tyres.
Ensure the panoramic sunroof tracks are cleaned and lubricated regularly to prevent binding and ensure the motor operates smoothly.
Check the coolant reservoir levels periodically to ensure there are no minor leaks within the complex intercooler circuit.
Use high-quality 98 octane fuel consistently to ensure the twin-turbo V8 performs within its designed parameters.
Estimated repair costs if issues arise
These performance rotors provide incredible stopping power but are a significant component of your future budget planning. Because they are large, two-piece floating rotors, they are more expensive than standard discs.
If the vehicle is equipped with adaptive air suspension, it is common to consider that air struts can eventually lose their seal. Setting aside a contingency fund for these is wise for long-term ownership.
The C63 S uses active engine mounts to balance comfort and handling. Over time, these may lose their hydraulic damping properties, and replacing them is a substantial job that requires careful planning.
