The Audi A3 Sportback 2.0 TDI (170 hp) S tronic, launched in 2009 as part of the 8PA facelift, aimed to provide a compelling blend of efficiency and performance within the premium compact segment. This variant occupied a sweet spot in the A3 lineup, offering more power and a more sophisticated driving experience than the entry-level 1.6 TDI models, while remaining more accessible than the range-topping 2.0 TFSI petrol versions. The S tronic transmission, a six-speed dual-clutch unit, was a key selling point, offering quicker and smoother gear changes compared to a traditional automatic.
Powertrain & Engine Architecture
At the heart of this A3 variant lies the Volkswagen Group’s 2.0-liter four-cylinder diesel engine, specifically the CBBB or CFGB engine code. This engine is a common-rail direct injection (CRDI) unit, utilizing piezo injectors for precise fuel delivery. The engine benefits from a turbocharger with an intercooler, boosting power output to 170 horsepower at 4200 rpm and 350 Nm (258 lb-ft) of torque between 1750 and 2500 rpm. The dual overhead camshafts (DOHC) operate four valves per cylinder, optimizing gas flow. The S tronic transmission is a seven-speed dual-clutch gearbox, known for its rapid shifts and efficiency. It operates with two separate clutches, one for odd gears and one for even gears, allowing for pre-selection of the next gear and seamless transitions.
Driving Characteristics
The 2.0 TDI with the S tronic transmission delivers a noticeably more responsive driving experience than the lower-powered A3 variants. The readily available torque makes for effortless cruising and confident overtaking. While not a sports car, the 0-60 mph time of around 7.3 seconds is respectable for a diesel-powered hatchback. The S tronic transmission contributes to a smooth and refined ride, with minimal torque interruption during gear changes. Compared to the six-speed manual transmission available on other A3 models, the S tronic offers convenience and quicker acceleration, but some enthusiasts might find it less engaging. The gear ratios are tuned for a balance of acceleration and fuel economy, with a relatively tall final drive to maximize efficiency on the highway.
Equipment & Trim Levels
The 2.0 TDI S tronic typically came equipped with a generous level of standard features. These included air conditioning, alloy wheels (usually 16 or 17 inch), a multi-function steering wheel, and an Audi Concert audio system. Higher trim levels, such as Sport or S-line, added features like sport seats, upgraded interior trim, and exterior styling enhancements. Optional extras included a panoramic sunroof, navigation system, parking sensors, and xenon headlights. Interior upholstery was typically cloth, with leather options available as an upgrade. The dashboard layout was typical of the 8PA A3, characterized by a clean and functional design.
Chassis & Braking
The A3 Sportback 2.0 TDI utilized a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable yet controlled ride. The suspension setup was tuned to balance handling and comfort, making it suitable for both city driving and longer journeys. Braking duties were handled by ventilated discs at the front and solid discs at the rear, with ABS (Anti-lock Braking System) as standard. The steering was a rack and pinion system, offering precise and responsive control. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Audi A3 2.0 TDI S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, and comfortable ride. Fuel economy was a major selling point, with combined figures around 50 mpg being achievable in real-world driving. Compared to the 1.6 TDI, the 2.0 TDI offered a significant performance boost, while the S tronic transmission provided a more sophisticated driving experience. Against the 2.0 TFSI petrol models, the TDI offered superior fuel economy, but at the expense of outright performance. Reliability was generally good, although the diesel particulate filter (DPF) could be a potential issue if the vehicle was primarily used for short trips.
Legacy
The Audi A3 8PA 2.0 TDI S tronic remains a popular choice in the used car market. The engine and transmission combination is known for its durability, provided it has been properly maintained. Regular servicing, including oil changes and DPF regeneration, is crucial for long-term reliability. While newer A3 generations offer more advanced technology and features, the 8PA model still provides a compelling package for those seeking a refined and efficient compact hatchback. The 2.0 TDI engine, in particular, has proven to be a robust and reliable unit, capable of covering high mileages with proper care.
