The Audi A4 allroad (B9 8W) 2.0 TDI 190 hp quattro ultra, produced from 2017 to 2018, represents a specific configuration within the broader B9 allroad lineup. Positioned as a mid-range offering, this variant combined the practicality of a station wagon (estate) with Audi’s renowned quattro all-wheel-drive system and a fuel-efficient diesel engine. It aimed to bridge the gap between the more basic A4 models and the higher-performance or luxury-focused trims. The B9 generation A4 allroad, built on the MLB Evo platform (shared with other Volkswagen Group vehicles), sought to provide a more rugged and capable alternative to the standard A4 Avant, appealing to drivers seeking a vehicle suitable for both daily commuting and occasional off-pavement excursions.

Powertrain & Engine Architecture
The heart of this A4 allroad variant is the 2.0-liter four-cylinder diesel engine, specifically the DETA engine code. This engine is a member of the Volkswagen Group’s modular engine family, known for its compact dimensions and efficiency. It utilizes a common rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimized combustion. The DETA engine features a single turbocharger with an intercooler, boosting power output and improving torque delivery. The engine also incorporates a diesel particulate filter (DPF) to reduce harmful emissions, meeting Euro 6 standards. The six-speed manual transmission was the standard offering, providing a balance between fuel economy and driver engagement. The quattro ultra system, a sophisticated on-demand all-wheel-drive system, engages the rear axle only when needed, improving fuel efficiency during normal driving conditions.
Driving Characteristics
The 190 hp 2.0 TDI engine, coupled with the six-speed manual transmission, provided a respectable level of performance for the A4 allroad. Acceleration from 0 to 60 mph took approximately 7.2 seconds. While not a sports car, the engine delivered ample torque (400 Nm or 295 lb-ft) from low engine speeds, making it well-suited for everyday driving and overtaking maneuvers. The manual transmission allowed for greater driver control, but the gear ratios were tuned for fuel efficiency rather than outright performance. Compared to the higher-output 2.0 TDI variants (typically around 200-210 hp) or the petrol-powered A4s, this version offered a more economical driving experience, albeit with slightly less spirited acceleration. The quattro ultra system provided enhanced traction in slippery conditions, making it a capable all-weather vehicle.
Equipment & Trim Levels
The A4 allroad 2.0 TDI 190 hp quattro ultra typically came equipped with a generous array of standard features. These included automatic climate control, a multi-function steering wheel, power windows and mirrors, and an infotainment system with a color display. Upholstery was typically cloth, with leather options available as an upgrade. Standard safety features included ABS, electronic stability control, and multiple airbags. Optional extras included navigation system, parking sensors, a panoramic sunroof, and upgraded audio systems. The allroad trim level itself added unique exterior styling elements, such as flared wheel arches, roof rails, and underbody protection, giving it a more rugged appearance.
Chassis & Braking
The A4 allroad featured a fully independent suspension system, with multi-link setups at both the front and rear. This provided a comfortable ride quality and good handling characteristics. The suspension was tuned to offer a balance between comfort and stability, suitable for both on-road and light off-road driving. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power. The ABS system helped to prevent wheel lockup during hard braking, enhancing safety.
Market Reception & Comparison
The A4 allroad 2.0 TDI 190 hp quattro ultra was generally well-received by automotive critics. It was praised for its practicality, fuel efficiency, and all-weather capability. However, some reviewers noted that the manual transmission could feel a bit notchy, and the engine, while capable, wasn’t as refined as some of its competitors. Compared to other trims in the A4 lineup, this variant offered a compelling combination of features and performance for the price. It was a popular choice for buyers who wanted a versatile and economical vehicle with all-wheel drive.
Legacy
The DETA engine, while generally reliable, is known to have potential issues with the DPF system and the EGR valve, particularly if not properly maintained. Regular servicing and the use of high-quality diesel fuel are crucial for ensuring long-term reliability. In the used car market, the A4 allroad 2.0 TDI 190 hp quattro ultra remains a popular choice, offering a good balance of practicality, comfort, and fuel efficiency. Its robust build quality and all-wheel-drive system make it a capable and dependable vehicle for a variety of driving conditions.
