The Audi A4 35 TDI (150 hp) S tronic, produced from 2018 to 2019, represents a significant iteration within the B9 (8W) generation of Audi’s popular compact executive car. This variant, introduced with the facelift of the B9 platform, aimed to balance fuel efficiency with acceptable performance for the European market, where diesel engines remained dominant. Positioned as a mid-range offering, it slotted below the more powerful 40 TDI and petrol-powered variants, and above the entry-level A4 models. The 35 TDI was primarily sold in Europe and other markets where diesel fuel was readily available and preferred.

INTRODUCTION
The Audi A4 35 TDI S tronic, launched as part of the B9 facelift in 2018, was designed to appeal to buyers seeking a balance between economy and usability. It utilized a 2.0-liter turbocharged diesel engine paired with Audi’s seven-speed S tronic dual-clutch transmission. This combination aimed to deliver improved fuel efficiency and reduced emissions compared to higher-powered variants, while still providing adequate performance for everyday driving. The B9 A4, overall, represented a significant step forward in terms of technology and refinement for Audi’s best-selling model, and the 35 TDI played a key role in its success in the European market.
Powertrain & Engine Architecture
At the heart of the 35 TDI lies the Volkswagen Group’s EA288 engine family, specifically the DEUA code. This is a 2.0-liter inline-four cylinder diesel engine featuring common-rail direct injection and a turbocharger with an intercooler. The engine produces 150 horsepower at 3250-4200 rpm and 320 Nm (236 lb-ft) of torque between 1500-3250 rpm. The common-rail system, operating at very high pressures, ensures precise fuel delivery for optimal combustion. The engine also incorporates a diesel particulate filter (DPF) to reduce harmful emissions, complying with stringent Euro 6d-TEMP standards. The S tronic seven-speed dual-clutch transmission provides quick and smooth gear changes, contributing to both performance and efficiency. This transmission features two separate clutches, allowing for pre-selection of the next gear, resulting in near-seamless shifts.
Driving Characteristics
The 35 TDI S tronic offers a comfortable and refined driving experience. While not as overtly sporty as the higher-powered A4 variants, it provides sufficient acceleration for most driving situations. The 0-100 km/h (0-62 mph) sprint takes approximately 8.9 seconds. The S tronic transmission contributes to a responsive feel, and the engine delivers a broad torque band, making it easy to maintain speed on highways and navigate city traffic. Compared to a manual transmission version (which wasn’t widely available in this configuration), the S tronic offers greater convenience and smoother shifts. However, some drivers might find the automatic transmission less engaging than a traditional manual. Compared to the 40 TDI, the 35 TDI feels noticeably less powerful, particularly during overtaking maneuvers.
Equipment & Trim Levels
The A4 35 TDI S tronic typically came well-equipped, even in base trim. Standard features generally included Audi’s MMI infotainment system with a 7-inch display (larger screens were optional), automatic climate control, power windows, and a leather-wrapped steering wheel. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Higher trim levels offered options like Audi’s Virtual Cockpit (a fully digital instrument cluster), navigation system, premium sound system, and leather upholstery. Exterior options included various wheel designs, LED headlights, and metallic paint finishes.
Chassis & Braking
The A4 B9 utilizes a sophisticated chassis design featuring independent multi-link suspension at both the front and rear. This setup provides a comfortable ride and good handling characteristics. The 35 TDI variant, due to its lower power output and weight compared to higher-spec models, generally featured slightly softer spring rates. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and electronic stability control are standard features, enhancing safety and control.
Market Reception & Comparison
The Audi A4 35 TDI S tronic was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the engine lacked the outright performance of its more powerful siblings. Compared to the A4 40 TDI, the 35 TDI offered a more affordable entry point into the A4 range, but at the expense of performance. In terms of fuel economy, the 35 TDI consistently outperformed the petrol-powered variants, making it a popular choice for drivers covering long distances. Reliability reports suggest that the EA288 engine and S tronic transmission are generally reliable, although regular maintenance is crucial, particularly regarding the DPF.
Legacy
The Audi A4 35 TDI S tronic remains a popular choice in the used car market, particularly in Europe. Its combination of fuel efficiency, comfort, and reliability makes it an attractive option for buyers seeking a practical and well-built compact executive car. While diesel engines have faced increased scrutiny in recent years, the A4 35 TDI, when properly maintained, continues to offer a compelling ownership experience. The longevity of the S tronic transmission, when serviced according to Audi’s recommendations, is a key factor in its continued desirability. The B9 A4, as a whole, is considered a well-engineered and refined vehicle, and the 35 TDI variant represents a sensible and economical choice within the range.
