General Maintenance Overview

Audi recommends a service interval of every 12 months or 10,000 miles (15,000 km), whichever comes first. However, depending on your driving style and conditions, certain components may need attention more frequently. It’s important to adhere to these service intervals to keep the vehicle in optimal running condition.

Service Intervals and Key Maintenance Tasks

Every 10,000 Miles (15,000 km) or 12 Months:

The first major service interval typically focuses on routine checks and minor maintenance tasks. Some of the key items covered during this service include:

  • Engine Oil and Filter Change: Essential for keeping the engine lubricated and running smoothly. Audi recommends changing the oil and filter at this interval to ensure the engine is protected from wear.
  • Brake Fluid Check and Replacement: Brake fluid should be checked for moisture content and replaced if necessary. Over time, brake fluid can absorb moisture, which can reduce braking performance.
  • Air Filters: The air filter helps ensure clean air enters the engine. It should be inspected, and if necessary, replaced during this service to avoid engine performance issues.
  • Tyre Inspection and Rotation: Tyres should be checked for uneven wear and rotated to promote even wear patterns. Audi recommends replacing tyres when tread depth reaches 3mm or lower.
  • Fluid Checks: All major fluid levels should be checked, including coolant, power steering fluid, and transmission fluid. Top-ups or changes should be carried out if required.
  • Inspection of Drive Belts and Hoses: The belts and hoses should be visually inspected for any signs of wear, cracks, or leaks.

2. Every 20,000 Miles (30,000 km) or 24 Months:

The second major service interval involves more detailed checks and potential component replacements. Key tasks during this service include:

  • Engine Air Filter Replacement: If it wasn't changed during the previous service, the engine air filter should be replaced at this stage.
  • Cabin Air Filter Replacement: Ensures that air inside the cabin remains fresh. It’s essential for maintaining the air quality and the performance of the climate control system.
  • Spark Plugs: Depending on the model and engine, the spark plugs may need to be replaced to ensure proper engine firing and fuel efficiency.
  • Brake Pads and Discs Check: Brake pads should be checked for wear, and the brake discs should be inspected for any damage or excessive wear.
  • Battery Condition Check: Ensure the battery is in good condition and that terminals are clean and corrosion-free.

3. Every 40,000 Miles (60,000 km) or 48 Months:

This is the interval where more significant maintenance may be required. In addition to the checks from the previous services, you can expect:

  • Transmission Fluid Check: For automatic transmissions, Audi recommends checking the fluid level and quality. If necessary, a fluid change can help prolong the life of the gearbox.
  • Coolant System Inspection: The cooling system, including the radiator and hoses, should be inspected for any signs of leaks or damage. Replacing coolant at this stage is often recommended to prevent overheating issues.
  • Timing Belt and Tensioner: While the RS4 and RS5 B9 models are equipped with timing chains, which generally require less maintenance, the system should still be inspected for wear or damage at this interval.

4. Every 60,000 Miles (90,000 km) or 72 Months:

At this stage, the car will require more comprehensive checks, including:

  • Differential and Final Drive Oil: Audi recommends changing the differential and final drive oils to ensure that the Quattro system continues to perform optimally. This is particularly important for those who drive their RS4 or RS5 in demanding conditions.
  • Brake System Overhaul: At this interval, it’s worth having the entire braking system thoroughly inspected, including the brake lines, master cylinder, and calipers. Replacing the brake fluid is also part of this check.
  • Suspension Components: The suspension system should be checked for wear, including the shock absorbers and bushings. Any worn parts should be replaced to maintain the car’s handling characteristics.

Other Considerations

  • Performance Parts: Audi RS models are designed for high-performance driving. Therefore, if you’ve fitted aftermarket parts, such as performance brakes, suspension, or exhaust systems, ensure they are regularly checked and maintained according to the manufacturer's guidelines.
  • Driving Conditions: If you frequently drive in harsh conditions (e.g., short trips, stop-and-start traffic, extreme temperatures, or on poor roads), you may need to shorten the service intervals. Regular checks of the tyres, brakes, and fluid levels are especially important in such conditions.

Conclusion

Maintaining your Audi RS4 or RS5 B9 is vital to ensuring that it continues to deliver the high-performance experience Audi is known for. By following the manufacturer’s recommended service intervals and staying on top of regular maintenance tasks, you can avoid costly repairs and keep your car in top shape for many years to come. Always refer to the official Audi service schedule, and if in doubt, consult a professional Audi technician to help with more specific maintenance needs.
