Audi TT (8J): A Comprehensive Buyer's Guide
The Audi TT, a name derived from the Tourist Trophy motorcycle race held on the Isle of Man, is a 2-door sports car marketed by Audi since 1998. Characterized by its distinctive Bauhaus-inspired styling and spirited performance, the TT aims to blend engaging handling with everyday usability. The second generation, known as the 8J, is the focus of this guide.
Class of Car
The Audi TT (8J) occupies a unique space in the automotive market. It is generally classified as a compact sports car or a grand tourer (GT). It competes with vehicles like the BMW Z4, Mercedes-Benz SLK (later SLC), Nissan 370Z, and Porsche Cayman, albeit at a slightly lower price point than the latter in many configurations.
Generations
- 1st Generation (8N): 1998-2006: The original TT, known for its iconic design, debuted with a 1.8-liter turbocharged engine.
- 2nd Generation (8J): 2006-2014: This guide focuses on the 8J generation. Key changes included:
- New aluminum and steel spaceframe (Audi Space Frame - ASF), improving weight distribution and rigidity.
- Introduction of the 2.0-liter TFSI engine with direct injection.
- Magnetic Ride adaptive damping system became an available option.
- More aggressive styling, moving away from the pure Bauhaus curves of the 8N.
- Available in Coupe and Roadster (convertible) body styles.
- 3rd Generation (8S/FV): 2014-2023: Featured a more angular design language and further technological advancements.
Reliability & Common Issues (8J)
The Audi TT (8J) generally offers good reliability, but like any car, it has its share of potential issues. Thorough maintenance records are crucial when considering a used 8J.
Engine Issues:
- 2.0 TFSI (EA113 & EA888):
- Cam Follower Wear (EA113): The high-pressure fuel pump cam follower (driven by the camshaft) is a well-documented weak point on earlier 2.0 TFSI engines (EA113). Failure of this follower can lead to fuel pump damage, camshaft damage, and even engine failure. Regular inspection and replacement (every 30-50k miles) is crucial. This issue is less prevalent in later EA888 engines.
- Oil Consumption (EA888): Some EA888 engines, particularly those from the earlier years, are known for excessive oil consumption. This can be caused by piston ring design issues or faulty PCV valves. Regular oil level checks are essential, and a compression test can help diagnose worn piston rings.
- Diverter Valve Failure: The diverter valve, which recirculates boost pressure, is prone to failure, leading to a loss of power. A revised, stronger diverter valve is available.
- Timing Chain Tensioner (EA888): Although not as widespread as on some other VW/Audi models, the timing chain tensioner can fail, leading to timing chain rattle and potential engine damage. Listen for unusual noises at startup.
- Carbon Buildup (Direct Injection Engines): Direct injection engines are susceptible to carbon buildup on the intake valves, which can reduce performance and fuel economy. Regular intake valve cleaning (walnut blasting) may be necessary.
- 3.2 VR6:
- Timing Chain Stretch: The VR6 engine is known for timing chain issues, particularly timing chain stretch. This can lead to poor performance and eventual engine failure if not addressed. Listen for a rattling noise at startup or when idling.
- Oil Leaks: VR6 engines can be prone to oil leaks from various seals and gaskets.
Transmission Issues:
- DSG (S Tronic) Transmission:
- Mechatronic Unit Failure: The DSG's mechatronic unit (the electro-hydraulic control unit) can fail, leading to erratic shifting, limp mode, or complete transmission failure. Regular DSG fluid changes are crucial (every 40,000 miles or so).
- Clutch Wear: The DSG is a dual-clutch transmission, and the clutches can wear out over time, particularly with aggressive driving.
- Manual Transmission:
- Generally reliable, but clutch wear is dependent on driving style.
Suspension & Brakes:
- Magnetic Ride Suspension: If equipped, the Magnetic Ride dampers can fail, leading to a loss of damping control. Replacement dampers are expensive. Check for fluid leaks and listen for unusual noises from the suspension.
- Wheel Bearings: Wheel bearings can wear out, especially on higher mileage examples.
- Brake Wear: Regular brake pad and rotor replacement is necessary. Check for uneven brake wear, which could indicate other issues.
Electrical & Other Issues:
- Instrument Cluster Issues: Some 8Js have experienced issues with the instrument cluster, such as pixelation or complete failure.
- Convertible Top Problems (Roadster): The convertible top mechanism can be complex and prone to problems, such as leaks, motor failure, or sensor issues. Thoroughly inspect the operation of the top and check for leaks.
- Central Convenience Module: Issues with door locks and window regulators can sometimes be traced to a faulty central convenience module.
Driving Experience
The Audi TT (8J) provides a compelling driving experience, blending performance with a touch of luxury.
Pros:
- Agile Handling: The TT offers sharp handling and good grip, making it enjoyable to drive on twisty roads. The Quattro all-wheel-drive system (on some models) further enhances handling and traction.
- Refined Interior: The interior is well-designed and features high-quality materials, creating a premium feel.
- Powerful Engines: Both the 2.0 TFSI and 3.2 VR6 engines offer strong performance and responsive acceleration.
- Distinctive Styling: The TT's distinctive styling sets it apart from other sports cars.
- Available Convertible Top: The Roadster version offers open-air driving enjoyment.
Cons:
- Rear Seats: The rear seats are small and best suited for children or cargo.
- Firm Ride: The ride can be firm, especially on models with the sport suspension or larger wheels.
- Potential Reliability Issues: As discussed above, the TT (8J) has some potential reliability issues that need to be considered.
- Running Costs: Maintenance and repair costs can be higher than average for a sports car.
Buying Advice
Here's some advice to help you find the right Audi TT (8J):
Years to Look For:
- 2010-2014 (Late Model EA888): Later models (2010 and newer) generally benefit from improvements and refinements, particularly regarding the EA888 engine's oil consumption issues. The EA888 engine is generally considered to be more reliable than the earlier EA113 engine.
- Models with Thorough Service Records: Prioritize examples with complete and well-documented service history. This indicates that the car has been properly maintained and that any potential issues have been addressed promptly.
What to Avoid (or be cautious of):
- Early 2.0 TFSI (EA113) without Cam Follower Service History: If considering an earlier 2.0 TFSI, ensure that the cam follower has been regularly inspected and replaced. Evidence of this service is essential.
- High Mileage Examples with Neglected Maintenance: Avoid examples that appear to have been neglected or that have a questionable service history.
- Magnetic Ride Suspension Failures: Thoroughly test the Magnetic Ride suspension (if equipped) and check for any signs of failure.
- Models with Unexplained Warning Lights: Be wary of cars with warning lights illuminated on the dashboard, as this could indicate underlying problems.
- VR6 Models with Timing Chain Rattle: Listen carefully for timing chain rattle on VR6 models, especially at startup.
Key Things to Check During Inspection:
- Cam Follower (2.0 TFSI EA113): Inspect the condition of the cam follower.
- Oil Level and Consumption: Check the oil level and ask about oil consumption.
- DSG (S Tronic) Functionality: Ensure smooth and precise shifting from the DSG transmission.
- Convertible Top Operation (Roadster): Thoroughly test the operation of the convertible top and check for leaks.
- Suspension and Brakes: Check the condition of the suspension components and brakes.
- Electronics: Verify that all electronic systems, including the instrument cluster, lights, and power windows, are functioning correctly.
- Obtain a Pre-Purchase Inspection (PPI): Have a qualified mechanic perform a pre-purchase inspection to identify any potential issues before you buy.
By carefully considering these factors, you can find a well-maintained Audi TT (8J) that provides years of driving enjoyment.
