Engine Maintenance

The Audi TTS 8J is powered by a 2.0-litre turbocharged engine, known for its performance but also for being sensitive to maintenance. Regular checks and oil changes are vital to keeping it running smoothly.

• Oil Change: Audi recommends an oil change every 10,000 miles (16,000 km) or every 12 months, whichever comes first. If you're driving the car hard or taking it to the track, you may want to reduce this interval to maintain engine health.
• Timing Chain: The timing chain should be inspected around the 100,000-mile (160,000 km) mark. While Audi’s engines are known for their longevity, neglecting the timing chain could result in significant damage. Listen for unusual engine noise or rattling, which could be a sign of wear.

Brakes and Suspension

Given the TTS’s performance capabilities, keeping the brakes and suspension in top shape is essential for both safety and driving enjoyment.

• Brake Pads and Discs: Check the brake pads every 15,000 miles (24,000 km), or sooner if you notice a decrease in braking performance or hear squeaking. Brake discs should be inspected every 30,000 miles (48,000 km) to check for warping or excessive wear. Check out our range of aftermarket disc options here
• Suspension: The TTS’s sport-tuned suspension might start to show signs of wear around the 50,000-mile (80,000 km) mark, particularly if you’re driving on uneven roads or pushing the car to its limits. If the ride becomes uncomfortable or you hear clunking noises, it’s time to have the suspension components inspected. Does your suspension need some love? We have you covered!

Clutch and Transmission

Whether you have the manual gearbox or the DSG (Direct Shift Gearbox), maintaining the clutch and transmission is crucial for smooth shifting and reliable performance.

• Manual Transmission: The clutch in the manual TTS can wear out more quickly, particularly if you frequently drive in a performance manner. Check for signs of slippage or difficulty in shifting, and consider replacing the clutch around the 60,000-mile (96,000 km) mark, depending on driving style.
• DSG Gearbox: The DSG transmission requires specific care to ensure longevity. Audi recommends changing the DSG transmission fluid every 40,000 miles (64,000 km) to maintain smooth gear changes and prevent potential transmission issues.

Turbocharger and Intercooler

As a turbocharged vehicle, the TTS 8J’s turbocharger needs attention to maintain optimal performance.

• Turbocharger: Ensure that the turbo is running smoothly by changing the engine oil regularly and using high-quality oil. Sludge can build up in the turbo over time if the oil is neglected. If you notice a decrease in power or hear unusual whining noises, the turbo may need to be inspected.
• Intercooler: The intercooler ensures that the air entering the engine is cool, which is vital for optimal performance. If the TTS starts to feel sluggish, it could be a sign that the intercooler is clogged or damaged. These issues are rare but should be checked if you notice a power loss.

Cooling System

The TTS's cooling system is critical to maintaining engine temperatures, especially under heavy use.

• Coolant Fluid: Check the coolant levels every 30,000 miles (48,000 km) or every two years, whichever comes first. If the coolant is low or dirty, it could lead to engine overheating. It’s a good idea to flush the cooling system every 60,000 miles (96,000 km) to ensure it’s working optimally.
• Radiator and Hoses: Inspect the radiator and hoses for any cracks or leaks. The rubber hoses can degrade over time, and leaks can cause coolant loss and engine damage. Check the hoses at least every 50,000 miles (80,000 km) or when performing routine servicing.

Electronics and Sensors

Modern Audi vehicles, including the TTS 8J, are packed with electronic components that can require attention over time.

• Oxygen and Mass Airflow Sensors: These sensors help regulate engine performance and fuel efficiency. If you notice rough idling, reduced fuel economy, or increased emissions, have these sensors checked. They should be cleaned or replaced around 60,000 miles (96,000 km) if you’re noticing performance issues.
• Battery: The TTS’s battery should be inspected every 3 years, particularly if you notice any issues with starting or electrical accessories. A healthy battery ensures that the vehicle’s electrical system functions properly, especially with all the advanced features in the TTS.

Exhaust System and Catalytic Converter

A healthy exhaust system is vital for performance and emissions compliance.

• Exhaust Inspection: The exhaust system, including the catalytic converter, should be inspected for leaks or damage every 40,000 miles (64,000 km). A blocked or failing catalytic converter can cause a decrease in power and efficiency, so early detection is important.

Service Intervals Summary

Here’s a quick recap of the recommended service intervals for the Audi TTS 8J:

• Oil Change: Every 10,000 miles (16,000 km) or 12 months
• Timing Chain: Inspect at 100,000 miles (160,000 km)
• Pollen Filter: Change at 2 years, or 20,000 miles
