Mercedes A35 AMG W177 Maintenance Guide
Mercedes AMG A35 W177 Maintenance Guide
The Mercedes AMG A35 W177, with its 2.0-litre turbocharged engine, offers impressive performance and driving dynamics. However, like any performance-oriented vehicle, regular maintenance is essential to ensure it continues to operate at its best. This guide will provide you with essential information on maintaining your A35 AMG, covering the service intervals, recommended maintenance tasks, and what to look out for in the long run.
Service Intervals: A and B Service
Mercedes-Benz uses a flexible service system that divides maintenance into two types: A Service and B Service. These services are scheduled based on time or distance, whichever comes first. Below are the key details you need to know about these service intervals for the A35 AMG:
A Service
The A Service is generally scheduled every 12 months or 12,000 miles (20,000 km), whichever comes first. This service focuses on the following tasks:
- Oil Change: The engine oil and oil filter will be replaced. This is crucial for ensuring the longevity of the engine and maintaining optimal performance, especially with a turbocharged engine.
- Brake Fluid Check: The brake fluid will be checked for level and condition, ensuring that the braking system operates efficiently.
- Fluid Levels Check: Other essential fluids such as coolant, power steering fluid, and windscreen washer fluid will be topped up if necessary.
- Tire Condition Check: The tires will be inspected for wear and proper pressure.
- Visual Inspection: A general inspection of the car’s key components, including lights, wipers, and exhaust system.
B Service
The B Service is typically scheduled every 24 months or 24,000 miles (40,000 km), whichever comes first. This is a more comprehensive service compared to the A Service and includes all the tasks from the A Service, plus:
- Air Filter Replacement: The cabin air filter will be replaced, ensuring clean air inside the vehicle for both the engine and the cabin.
- Spark Plugs Check/Replacement: Spark plugs will be checked and replaced if necessary to ensure the engine runs smoothly and efficiently.
- Brake Pads and Discs Check: A more thorough inspection of the braking system will be carried out, including brake pad thickness and disc condition.
- Engine and Transmission Inspection: The engine, gearbox, and exhaust system will be checked for any signs of wear or issues that might affect performance.
- Suspension Check: The suspension system, including shocks and springs, will be inspected for wear.
Both the A and B services are critical to maintaining your vehicle’s performance, and it’s important to keep track of when these services are due. Mercedes-Benz uses a service indicator that will display a warning when your vehicle requires service, but it’s still wise to follow the recommended intervals to avoid any issues.
Additional Maintenance Tips
While the A and B services cover the majority of routine maintenance, there are a few additional items to keep an eye on as an AMG owner:
Turbocharged Engine Maintenance
The A35 AMG’s 2.0-litre turbocharged engine is designed for performance, but it requires proper care to ensure longevity. Regular oil changes are particularly important to keep the turbocharger running smoothly, as lack of proper lubrication can cause premature wear. Check the oil level regularly and ensure that the oil used meets Mercedes-Benz's specifications.
Transmission Care
The A35 features a dual-clutch automatic transmission, which delivers fast gear shifts but can be sensitive to neglect. It's important to check for any signs of irregular shifting or unusual noises. If you notice jerking or hesitation when changing gears, it may indicate an issue with the transmission. Ensure that the gearbox fluid is replaced according to the manufacturer’s recommendations, even if the vehicle isn’t heavily driven.
Suspension and Handling
The A35 features an advanced suspension system with options like AMG Ride Control for a more dynamic driving experience. Over time, suspension components can wear, especially if the car has been driven hard. Regularly inspect the suspension for any signs of wear, and check for any knocking or unusual noises when driving over bumps or uneven surfaces.

Brakes and Tyres
Given the performance nature of the A35, the brakes will be under more strain than those on a regular hatchback. It's essential to check the condition of the brake pads and discs at regular intervals. You may need to replace them more frequently, depending on driving habits. Likewise, regularly inspect the tyres for wear, ensuring they have sufficient tread depth, especially if you often push the car to its limits.

Mercedes-Benz Extended Warranty and Maintenance Packages
For new owners, Mercedes-Benz offers extended warranty options and service packages, which can provide additional peace of mind. These packages often cover the cost of routine services and repairs, including the A and B services, which can save you money over time. If you’re buying a used A35, it’s worth checking if there’s any remaining warranty or if you can purchase an extended warranty for added security.
Conclusion
The Mercedes AMG A35 W177 is a finely tuned performance hatchback that requires regular maintenance to keep it running at its best. Adhering to the A and B service intervals is crucial, with the A Service every 12 months or 12,000 miles (20,000 km), and the B Service every 24 months or 24,000 miles (40,000 km). Additionally, keeping an eye on components like the turbocharged engine, transmission, brakes, and suspension will ensure your A35 remains a reliable and enjoyable car to drive. Regular servicing, using genuine Mercedes-Benz parts, and paying attention to the specific needs of your vehicle will help maintain its performance and value over the years.
