The 2019 Audi A4 is a compact luxury sedan (also offered as the A4 allroad wagon) known for a refined cabin, confident handling, and premium tech. It’s ideal for drivers who want a quiet, upscale daily commuter that still feels sporty on back roads, without moving up to a larger midsize sedan. The 2019 model sits in the B9 generation (introduced for 2017), and it represents a mature point in the redesign with strong standard safety and infotainment features. In the market, it competes directly with the BMW 3 Series and Mercedes-Benz C-Class by blending all-weather capability with available quattro all-wheel drive and a high-end interior.

1) Turbocharged 2.0L engine: The 2019 A4 is powered by a 2.0-liter turbocharged inline-4 (TFSI) producing around 248 horsepower, paired with a 7-speed S tronic dual-clutch automatic transmission and available quattro AWD (front-wheel drive configurations also exist in some trims/markets). 2) Strong balance of comfort and handling: A well-tuned suspension and precise steering give the A4 a composed, German-sedan feel, especially on the highway and in sweepers. 3) Audi Virtual Cockpit (available): The configurable digital gauge cluster is one of the A4’s most sought-after features, integrating navigation, media, and vehicle data in a sharp display. 4) Modern infotainment and connectivity: An MMI infotainment system with smartphone integration (Apple CarPlay/Android Auto, depending on equipment) plus available navigation and premium audio makes it easy to live with daily. 5) Advanced driver assistance options: Depending on package, the A4 can include safety tech like adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, and parking aids.

Shoppers researching 2019 Audi A4 reliability and 2019 Audi A4 common issues will find that many owners report solid day-to-day dependability, but like most turbocharged German luxury cars, the A4 can be sensitive to maintenance and can be expensive when things do go wrong. 1) Water pump/thermostat housing coolant leaks: A frequent theme on modern Audi/VW 2.0T engines is coolant seepage or leaks from the water pump or thermostat housing area. This can show up around 30,000–70,000 miles with low coolant warnings, a sweet smell, or visible crusty residue near the front of the engine. 2) Oil consumption and minor leaks: Some owners report oil level dropping between services or small leaks (often from gaskets/seals). While not every car has it, it’s common enough that checking oil level regularly is wise—especially after 50,000+ miles or on vehicles with inconsistent service history. 3) S tronic (dual-clutch) drivability complaints: The 7-speed dual-clutch can feel hesitant at low speeds, with occasional jerky engagement in stop-and-go traffic. In some cases, owners cite mechatronics or clutch-related concerns, though many cars simply need up-to-date software and correct fluid service. 4) Electronics and sensor glitches: Infotainment freezing, Bluetooth connection drops, parking sensor faults, or warning lights tied to sensors can occur intermittently. These are often resolved with software updates, battery checks, or sensor replacement, but diagnosis can add cost.
