Regular Servicing
Audi recommends following a regular service schedule to keep the RS6/RS7 C8 in optimal condition. The standard service intervals for these models are as follows:
- Minor Service (Oil change and basic checks): Every 10,000 miles (16,000 km) or 1 year, whichever comes first.
- Major Service (Includes a full inspection, fluid changes, and other in-depth checks): Every 20,000 miles (32,000 km) or 2 years, whichever comes first.
At these intervals, the service includes the essential oil change, a check of all fluids, brake inspection, and other essential maintenance to keep the car running smoothly.
Oil Changes
The 4.0-litre twin-turbo V8 engine in the RS6/RS7 requires high-quality engine oil to function properly. Oil changes are a critical aspect of maintaining engine health, particularly for performance engines that endure high levels of stress. As mentioned, the recommended oil change interval is every 10,000 miles (16,000 km) or 1 year. Always ensure that the correct grade and specification of oil is used, as specified by Audi. Using the wrong oil can lead to excessive engine wear and potential damage.
Brake Fluid
Brake fluid absorbs moisture over time, which can reduce its effectiveness and damage the braking system. Audi recommends changing the brake fluid every 2 years, regardless of the vehicle’s mileage. This is a crucial maintenance task to ensure the RS6/RS7's powerful braking system continues to function correctly, especially when pushing the car to its performance limits.
Spark Plugs
The spark plugs on the RS6/RS7’s twin-turbo V8 should be replaced as part of the major service, which occurs every 20,000 miles (32,000 km) or 2 years. Worn spark plugs can cause misfires, rough idling, or decreased fuel efficiency, so regular replacement is important for smooth engine performance.
Air and Cabin Filters
Both the engine air filter and cabin air filter play important roles in ensuring optimal engine performance and interior comfort. The engine air filter should be replaced every 20,000 miles (32,000 km) or 2 years, while the cabin air filter should be changed at the same interval, or sooner if you notice reduced air quality or airflow inside the cabin.

Transmission Fluid
The RS6 and RS7 C8 are equipped with an eight-speed automatic transmission, which requires attention at regular intervals. Audi does not have a fixed schedule for changing the transmission fluid, but it’s important to keep an eye on its condition. If you notice any issues with shifting or transmission performance, it may be worth having the fluid checked or replaced. Typically, this may be necessary every 40,000 miles (64,000 km), but always refer to your specific car's service manual.
Timing Belts and Chains
The RS6/RS7 C8 uses a timing chain, rather than a timing belt, which generally requires less maintenance and has a longer lifespan. While timing chains do not need to be replaced at fixed intervals, it is important to monitor for any unusual noises or signs of wear. If you hear a rattling or clicking sound from the engine, it’s best to have the timing chain inspected.
Suspension and Steering
Due to the dynamic nature of the RS6/RS7, the suspension and steering components will undergo considerable stress, especially if the car is driven enthusiastically. The adaptive air suspension system, fitted as standard, requires regular checks for any signs of leaks or wear. Audi recommends checking the suspension system during each major service (every 20,000 miles/32,000 km or 2 years). Additionally, ensure that the steering system is functioning smoothly and that there are no unusual noises when turning the wheel.

Tyres and Alignment
Given the high-performance capabilities of the RS6/RS7, maintaining proper tyre condition is essential for both safety and performance. Regularly check tyre pressure and tread depth, as well as for any signs of uneven wear, which can indicate alignment issues. Audi recommends checking tyre condition at every service interval and performing an alignment if necessary, particularly if the car pulls to one side when driving.
Cooling System
The cooling system ensures the engine maintains optimal temperatures, especially during high-performance driving. Regular inspection of the coolant level and quality is essential. Audi recommends checking the coolant level at every service interval and replacing the coolant every 5 years or 60,000 miles (96,000 km).
Battery
With the advanced electronics and features in the RS6/RS7, it’s essential to keep the battery in good condition. Regularly check the battery’s charge level and look for any signs of corrosion around the terminals. Audi recommends replacing the battery every 4 to 5 years, but this may vary depending on driving conditions and usage.
Exhaust System
The RS6/RS7’s exhaust system is built to handle the immense power of the twin-turbo V8. Over time, it’s important to inspect the system for any signs of damage, leaks, or rust. Pay particular attention to the exhaust valves and catalytic converters. Any unusual noises, such as rattling or a loss of power, should be investigated.
Conclusion
Maintaining an Audi RS6 or RS7 C8 ensures that the vehicle continues to perform at its best and lasts for many years. By adhering to the recommended service intervals and staying on top of regular checks and maintenance tasks, you can enjoy the full performance potential of your RS6/RS7 without unnecessary repair costs.
Make sure to follow the Audi service schedule for oil changes, brake fluid replacements, and other critical tasks. Regular inspections of the suspension, tyres, and cooling system will also help maintain optimal performance. By doing so, you can ensure your RS6 or RS7 remains as thrilling to drive as the day it left the showroom.
