Audi TTRS 8S Maintenance Guide
Audi TTRS 8S Maintenance Guide (2016–2023)
The Audi TTRS 8S, powered by the 2.5-litre five-cylinder engine (DAZA), is a performance-oriented sports car that demands regular maintenance to ensure optimal performance and longevity. Whether you are a current owner or looking to purchase one, understanding the recommended maintenance schedule and common areas of concern is essential for keeping your TTRS in top condition.
In this guide, we’ll walk through the key maintenance points for the TTRS 8S, referencing the Audi service schedule, and highlighting areas you should keep an eye on. The engine and drivetrain of the TTRS 8S share many components with the facelifted Audi RS3 8V, so this guide will also be applicable for RS3 owners.

Engine Maintenance
The 2.5-litre DAZA engine, shared with the facelifted RS3 8V, is a high-performance unit. Regular servicing is crucial to ensure it continues to perform optimally.
Oil Changes
Engine oil should be replaced every 10,000 miles (or 12 months, whichever comes first). Regular oil changes help to maintain engine health, ensuring that the turbocharged engine is properly lubricated and running smoothly. Using the correct oil grade (5W-30 or 0W-40 synthetic) is important to keep the engine at its best.
Air Filter and Cabin Filter
The air filter helps maintain engine performance by ensuring clean air intake. Audi recommends replacing the air filter every 20,000 miles or every two years, depending on driving conditions. If you do a lot of city driving or driving in dusty conditions, you may need to replace it sooner. Similarly, the cabin filter should be changed every 20,000 miles or two years.

Fuel System
The fuel system should be inspected during each service. The fuel filter, which helps to prevent impurities from reaching the engine, typically needs replacing every 40,000 miles. Additionally, fuel injectors and pumps should be checked regularly to ensure optimal fuel delivery and combustion.
Timing Chain and Water Pump
The TTRS 8S shares many drivetrain components with the facelifted RS3 8V, and both models use a timing chain rather than a timing belt. The timing chain is generally more durable, but it should still be checked for wear and any signs of stretching. Timing chain replacement isn’t usually required under normal conditions but should be inspected every 60,000 miles for any signs of damage or excessive wear.
The water pump should also be checked at regular intervals to ensure it is functioning correctly. While the water pump doesn’t have a fixed replacement interval, it’s recommended to have it inspected during regular servicing, particularly if there are signs of overheating or coolant leaks.
Transmission Maintenance
The TTRS 8S uses a seven-speed dual-clutch transmission (S tronic), which provides quick gear changes and high-performance driving. However, the dual-clutch transmission requires regular attention to ensure smooth operation.
Transmission Fluid
Audi recommends replacing the transmission fluid every 40,000 miles. Regular fluid changes help maintain smooth shifting and prevent premature wear of the gearbox components. Always use the correct Audi-approved fluid to ensure compatibility with the transmission.
Clutch Pack
While the dual-clutch transmission is generally robust, it’s still important to monitor its performance. Signs of a worn clutch pack include hesitation or jerky shifting, particularly at lower speeds or during stop-start driving. If you notice these symptoms, it may be time for a professional inspection.
Brake System
The TTRS 8S comes with large, high-performance brakes that are capable of handling the car's significant power. Regular brake maintenance is critical for both safety and performance.
Brake Pads and Discs
Audi recommends inspecting the brake pads every 10,000 miles and replacing them as needed. The brake discs should also be inspected during each service, and they typically need replacing after 30,000 to 40,000 miles, depending on driving style. If you notice any vibrations, squealing, or reduced braking performance, it's worth getting the brake system checked.
Suspension and Steering
The TTRS 8S is equipped with Audi’s magnetic ride adaptive suspension, which adjusts the damping rate based on driving conditions. Regular checks of the suspension components will ensure that the car’s handling remains sharp.
Suspension and Dampers
Audi recommends inspecting the suspension system every 20,000 miles or two years. If you notice any unusual noises, such as clunks or rattles, or if the ride feels bouncy or unsettled, the suspension may need attention. Additionally, the dampers (part of the magnetic ride system) should be checked for fluid leaks or any signs of malfunction.

Steering System
Regular checks of the steering system, including the power steering fluid, should be done every 20,000 miles. Any steering issues, such as heavy steering or odd noises, should be addressed promptly to avoid further damage.
Tyres and Alignment
The TTRS 8S is fitted with high-performance tyres, and regular checks for tread wear and tyre pressure are essential for both safety and performance. Audi recommends checking tyre pressures monthly and inspecting tyres for any damage or uneven wear. Uneven wear can be a sign of alignment issues, which should be corrected to prevent further damage to the tyres and suspension components.
Service Intervals: Time vs Distance
According to Audi's official service schedule for the TTRS 8S, the following intervals should be adhered to for optimal maintenance:
- Oil Change: Every 10,000 miles or 12 months, whichever comes first.
- Air Filter: Every 20,000 miles or two years.
- Cabin Filter: Every 20,000 miles or two years.
- Fuel Filter: Every 40,000 miles.
- Transmission Fluid: Every 40,000 miles.
- Timing Chain Inspection: Every 60,000 miles.
- Brake Inspection: Every 10,000 miles.
- Suspension and Steering Check: Every 20,000 miles or two years.
These intervals are general guidelines, and if you drive in more demanding conditions (e.g. track use, frequent stop-start traffic), you may need to reduce these intervals to ensure longevity.
Conclusion
The Audi TTRS 8S is a high-performance machine that requires regular and diligent maintenance to keep it performing at its best. Following the recommended service intervals for oil changes, filters, transmission fluid, and more will ensure that the 2.5-litre DAZA engine and Quattro drivetrain remain in top shape. Whether you're a current owner or looking to purchase one, staying on top of these maintenance tasks will help you enjoy the full capabilities of the TTRS 8S while avoiding costly repairs in the future.
