Service Intervals: Distance and Time

Audi recommends specific service intervals for the TTS 8S to ensure the vehicle performs optimally and remains reliable. The intervals for major and minor servicing are based on either distance or time, whichever comes first.

Minor Service (Oil Change and Basic Checks)

A minor service typically involves an oil and filter change, as well as a general check-up of the vehicle’s systems. For the TTS 8S, Audi recommends this service at the following intervals:

• Every 10,000 miles (15,000 km) or 1 year, whichever comes first.

This service includes:

• Oil and filter change: Essential to maintain engine performance and prevent premature wear.
• Fluid levels check: Includes checking brake fluid, coolant, and other essential fluids.
• Inspection of tyres: Check tread depth and overall condition.
• Brake inspection: Check pads and discs for wear.
• General system checks: A basic inspection of various systems, including the exhaust and suspension.

Major Service

The major service is more comprehensive and includes everything in the minor service, with additional checks and replacements of more critical components. Audi recommends the major service at the following intervals:

• Every 20,000 miles (30,000 km) or 2 years, whichever comes first.

In addition to the tasks in the minor service, the major service includes:

• Replacement of cabin and air filters: Helps maintain air quality and engine efficiency.
• Brake fluid replacement: Ensures optimal braking performance, especially important in performance models like the TTS.
• Inspection of the cooling system: Check for leaks or signs of wear in the radiator and hoses.
• Spark plug inspection: Spark plugs should be checked for wear and replaced if necessary, depending on their condition.

Extended Service Intervals

For those who don’t drive the vehicle often or primarily use it for long-distance journeys, Audi has also included extended service intervals. These can be reviewed based on your driving conditions, and the car’s on-board diagnostics may also influence when service is due.

Additional Maintenance Tasks

While the above intervals cover most of the essential maintenance, there are a few other tasks and checks to be aware of, depending on the age and mileage of your TTS.

Timing Chain (EA888 Engine)

The 2.0 EA888 engine in the TTS 8S uses a timing chain, which generally does not require frequent replacement. However, it's important to ensure it is properly maintained to avoid potential issues. If you hear unusual rattling sounds from the engine, particularly at startup, it could indicate a problem with the timing chain, and it should be inspected.

Turbocharger Maintenance

The turbocharged engine in the TTS is an important component that requires some attention. While generally reliable, it’s wise to check for any signs of turbo wear, such as unusual whining noises or a decrease in performance. Regular oil changes and ensuring the turbo is running at optimal temperatures are key to its longevity.

Transmission Service

Whether your TTS 8S has the manual or dual-clutch S Tronic transmission, regular fluid checks and changes are important. Audi recommends that the S Tronic transmission fluid be replaced every 40,000 miles (64,000 km), although this can vary depending on driving conditions. If you notice any sluggish shifting or jerking, have the transmission checked immediately.

Brake Pads and Discs

Given the performance nature of the TTS, the braking system is a critical component. Brake pads should be checked at every service, particularly if you use the car for spirited driving. Audi recommends replacing brake pads approximately every 30,000 to 40,000 miles (48,000 to 64,000 km), but this can vary based on driving style. Brake discs should also be inspected regularly for any signs of warping or excessive wear.

Tyre Maintenance

Ensure that your tyres are regularly rotated and aligned, especially if you drive the TTS hard. The TTS 8S is equipped with performance tyres, and uneven wear can affect handling and safety. Check the tyre pressure regularly, as performance tyres may wear faster if underinflated.

Cooling System

The cooling system should be checked every two years or 20,000 miles (30,000 km). This includes inspecting the radiator, hoses, and coolant levels. Overheating can lead to serious engine damage, so make sure to address any leaks or issues promptly.

Special Maintenance Considerations

Driving Style

Your maintenance needs may vary depending on your driving style. If you often drive your TTS in high-performance conditions, such as track days or aggressive driving, you may need to service the car more frequently. This includes more regular checks on the brakes, suspension components, and tyres. For everyday driving, the service intervals outlined above should be sufficient to keep your vehicle in good condition.

Short Journeys

If your TTS is primarily used for short trips, the engine may not reach optimal operating temperatures, which can cause increased engine wear. In this case, it’s especially important to maintain the recommended service intervals, particularly for oil changes.

Climate and Road Conditions

Harsh climates and road conditions can also affect maintenance needs. For example, if you drive in areas with frequent snow or heavy rain, it’s crucial to check the brakes and tyres more regularly. Similarly, extreme heat can place extra strain on the engine and cooling system.

Conclusion

Regular maintenance is key to ensuring that your Audi TTS 8S remains reliable and performs at its best. By following Audi’s recommended service intervals of 10,000 miles (15,000 km) for minor services and 20,000 miles (30,000 km) for major services, you can avoid costly repairs and keep your TTS running smoothly for years. Pay attention to the engine, transmission, and braking systems, and don't overlook the importance of checking fluid levels, tyres, and suspension components. With proper care, the Audi TTS 8S can continue to deliver thrilling performance for a long time.
