Petrol
When cold starting the engine, listen carefully for any metallic rattling from the top of the engine, as this may indicate potential timing chain tensioner wear.
While driving at low speeds, navigate over some uneven road surfaces and listen for any knocking sounds from the suspension, specifically looking for signs of worn control arm bushings.
Check the infotainment system by scrolling through all menus; ensure the screen remains responsive and doesn't flicker, as these modules can occasionally present electronic quirks in this generation.
Monitor the transmission during gear changes at light throttle; it should feel smooth, but if you notice any harshness, it is worth asking to see if the gearbox fluid service records are up to date.
Usually marks the first significant service interval, including oil and cabin filter changes.
A major interval where spark plugs and transmission fluid services become highly recommended for ongoing engine health.
The time to look closely at cooling system components and potentially inspect suspension dampers for optimal handling.
Keep a consistent eye on engine oil levels, as these performance biturbo engines can consume a small amount of oil between services.
Ensure the cooling system is maintained, as the M177 engine runs at high temperatures and appreciates fresh coolant.
Regularly inspect your tyre tread and brake pad thickness, as the C63’s weight and torque can accelerate wear on these consumables.
Verify that the software has been kept up to date at your local Mercedes-Benz specialist during your scheduled visits.
Keep the service book stamped religiously, as full history is a significant factor in the long-term desirability of the W205 model.
Estimated repair costs if issues arise
Given the performance capabilities of the C63, you might eventually need to budget for high-performance brake components when the current set nears its wear limit.
If the vehicle is equipped with adjustable dampers, these can occasionally show signs of wear over time; it is wise to set aside some funds for eventual suspension refreshing.
Depending on the car's history, you might eventually need to budget for cooling system maintenance, such as water pump or expansion tank servicing, to maintain optimal engine temperatures.
