Regular Service Schedule: A Service and B Service

Mercedes-Benz uses a flexible service system for the C63 W205, typically consisting of A services and B services, with intervals based on distance or time, whichever comes first. The service schedule is designed to maintain the vehicle’s performance and prevent issues that could arise from neglect.

A Service

The A service is generally focused on simpler, more routine tasks such as oil and filter changes. This service should be done approximately every 12,000 miles or 1 year, whichever comes first. The key tasks performed during an A service include:

• Engine oil and oil filter change: Ensures the engine runs smoothly and that oil remains free of contaminants.
• Check and top up of fluids: Includes brake fluid, coolant, and windshield washer fluid.
• Tyre inspection: Checking tread depth and wear to ensure proper handling and safety.
• Brake inspection: Checking the condition of the pads and discs for wear.
• Exterior light check: Ensuring all lights are functioning correctly for visibility and safety.
• Battery check: Monitoring battery charge and condition to avoid unexpected failures.

B Service

The B service is more comprehensive and typically occurs every 24,000 miles or 2 years, whichever comes first. During this service, the technician will perform all the tasks covered in the A service, plus additional checks and maintenance. Tasks during the B service include:

• Air filter replacement: Helps ensure the engine receives clean air for combustion.
• Fuel filter inspection/replacement: Ensures the fuel system is operating efficiently.
• Spark plugs inspection/replacement: Ensures the engine runs smoothly and fuel is burned efficiently.
• Brake fluid replacement: Brake fluid can degrade over time, so this is replaced to maintain braking performance.
• Comprehensive inspection of suspension and drivetrain: Checks for any wear in components like shock absorbers, struts, and joints, ensuring optimal handling and performance.
• Cabin filter replacement: Maintains air quality inside the cabin, especially for those with allergies or sensitivities. Check out the K&N Lifetime Washable Cabin Air Filter for C63 W205

Key Maintenance Areas for the C63 W205

While the service intervals cover the basics, there are other areas to pay attention to in order to maintain the performance and reliability of your C63 W205. Here are the key components that require regular checks:

Engine and Turbochargers

The C63 W205 is powered by a 4.0-litre twin-turbocharged V8 engine, which is a significant improvement over the previous naturally aspirated V8. While this engine is generally reliable, it requires regular oil changes and inspections.

• Engine oil: Always use the recommended engine oil, as the turbocharged engine can be more sensitive to oil quality. Replace the oil every 12,000 miles or annually to avoid build-up and reduce engine wear.
• Turbochargers: The turbos can suffer from oil leaks, especially as the vehicle accumulates high mileage. It's important to monitor the turbocharger hoses and seals for any signs of oil leakage or reduced performance.

Brakes

Given the performance nature of the C63, the brakes are put under significant stress. Brake wear can be more frequent than on regular models, particularly if the car has been driven aggressively.

• Pads and discs: Check the brake pads and discs regularly for wear. High-performance brake pads and discs are available, but they may need replacing sooner than standard ones, depending on usage.
• Brake fluid: Replace the brake fluid every two years as per the service schedule, as it can degrade over time, affecting braking efficiency.

Suspension

The C63 W205 features AMG Ride Control suspension, which is adjustable and designed to offer both comfort and sporty handling. Over time, the suspension components, particularly the dampers and springs, can wear out. This is especially true if the car has been driven in a performance-oriented manner.

• Suspension wear: Pay attention to any unusual noises, like knocking or rattling, which could indicate worn suspension parts. Also, keep an eye on ride height to ensure the system is functioning correctly.
• Alignment: If you notice the car pulling to one side or uneven tyre wear, it may be time to check the wheel alignment.

Cooling System

The cooling system is vital in maintaining the proper operating temperature of the engine, particularly with a high-performance V8.

• Radiator and hoses: Inspect for any cracks or leaks in the radiator and coolant hoses. Overheating can lead to serious engine damage, so keeping the cooling system in good working order is essential.
• Coolant levels: Check the coolant level regularly and top up as needed. Replace the coolant according to the manufacturer’s recommendations to avoid corrosion and maintain proper engine cooling.

Other Considerations

Tire Maintenance

Tyres are a critical component of the driving experience, especially in a high-performance car like the C63. Regularly check the tyre tread depth and look for any signs of uneven wear, which could indicate alignment or suspension issues. It’s also important to ensure the tyres are inflated to the correct pressure, as under or over-inflation can affect handling and tyre longevity.

Exhaust System

The AMG performance exhaust system is one of the defining features of the C63 W205, providing a distinctive sound. Over time, exhaust components, particularly the catalytic converters and silencers, can wear. Pay attention to any unusual sounds, such as rattling, which could indicate a problem with the exhaust system.

Battery

As with any modern vehicle, the battery is crucial for starting the engine and running electrical systems. Have the battery tested regularly, especially if the car struggles to start. The C63 W205 is equipped with a high-performance battery, and replacing it with the correct type is essential for optimal electrical system performance.

Conclusion

Maintaining the Mercedes-Benz C-Class C63 W205 with its 4.0-litre turbocharged V8 requires regular attention to ensure it continues to perform at its best. Adhering to the service schedule with A and B services is essential for maintaining the engine, suspension, and brake systems. Additionally, staying on top of key maintenance areas such as the turbochargers, brakes, suspension, and cooling system will help prolong the life of your C63.

By following these guidelines and keeping a close eye on wear-and-tear components, you can enjoy your C63 W205 for many years while ensuring it continues to deliver an exciting and reliable driving experience.
