The 2014 Audi S4 is a compact luxury sport sedan that blends everyday comfort with serious performance, making it ideal for drivers who want an all-weather, all-season commuter that still feels quick and engaging. It sits in the B8.5-generation S4 lineup (a refreshed version of the B8), known for sharper styling and updated tech compared with earlier models. In the market, it competes with the BMW 335i/340i and Mercedes-Benz C-Class performance trims, but stands out for standard quattro all-wheel drive and strong midrange power. It’s a great fit for enthusiasts who need four doors, usable rear seats, and year-round traction without giving up a premium cabin.

- Supercharged V6 performance: A 3.0L supercharged V6 (TFSI) rated at 333 hp and 325 lb-ft delivers quick acceleration and strong passing power, with a broad torque curve that feels responsive in daily driving. - Transmission choices: Buyers could choose a 6-speed manual or a 7-speed S tronic dual-clutch automatic, giving the S4 appeal to both traditionalists and those who want fast, crisp shifts. - Standard quattro all-wheel drive: Audi’s quattro system provides confident traction in rain and snow and helps put power down cleanly, a key reason many shoppers consider the S4 over rear-wheel-drive rivals. - Sport-tuned chassis: A firmer suspension, performance brakes, and available sport differential (on many equipped cars) improve cornering balance and reduce understeer when driven hard. - Premium interior and tech: High-quality materials, supportive sport seats, and available MMI navigation/Bang & Olufsen audio help the S4 feel like a true luxury sedan, not just a fast one.

Shoppers often search “2014 Audi S4 reliability” and “2014 Audi S4 problems” because this model can be dependable when maintained, but it does have recurring trouble spots to know about. - Water pump and cooling system leaks: Many owners report coolant loss from the water pump/thermostat area, sometimes showing up as a sweet smell, low coolant warnings, or small puddles. This can occur around 60,000–100,000 miles, though earlier failures happen. Addressing leaks quickly helps prevent overheating and secondary damage. - PCV system and oil consumption/leaks: The crankcase ventilation (PCV) valve can fail and contribute to rough idle, whistling noises, or increased oil use. Some engines also develop oil leaks from gaskets/seals as mileage climbs (often 80,000+ miles), which can drip onto undertrays and create burning-oil odors. - DSG/S tronic drivability issues (automatic cars): Some S tronic-equipped S4s develop shuddering, harsh engagement, or hesitation, especially noticeable in stop-and-go traffic. While not every car is affected, higher-mileage examples (often 60,000–120,000 miles) may need fluid service, adaptation, or clutch/mechatronics-related repairs depending on symptoms. - Carbon buildup on intake valves: As a direct-injected engine, the 3.0T can accumulate intake valve deposits over time, leading to reduced performance, misfires, or poor fuel economy. It’s more common as mileage approaches 70,000–120,000 miles and is typically addressed with intake cleaning (often walnut blasting).
