Audi A3 8V (2012 – 2020)

Reliability score : 8.2/10

The third-generation Audi A3 (Type 8V) marked a major turning point for the Volkswagen Group by introducing the modular MQB platform. Available as a 3-door, Sportback (5-door), Sedan (Limousine), and Cabriolet, it redefined finish standards in the premium compact segment. Facelift: Introduced mid-2016 (Phase 2), it brought aesthetic updates (optional Matrix LED headlights), the integration of the Virtual Cockpit, and an update to the engines (arrival of the 1.0 TFSI, 1.5 TFSI, and 2.0 TFSI, the 1.6 TDI increasing from 110 to 115 hp). Diesel Focus: Unlike the previous generation (8P) affected by Dieselgate (EA189 engines), the A3 8V uses the EA288 family of diesel engines. These blocks are intrinsically more reliable, quieter, and compliant with Euro 6 standards (with the addition of AdBlue

🎯 Verdict

The Audi A3 8V is undoubtedly one of the most accomplished premium compacts of its decade. If you're targeting a diesel, the 2.0 TDI (150 or 184 hp) is the preferred choice: it erases the flaws of the old generation, offers superior driving pleasure, and proves very robust provided you monitor the cooling system (water pump, silicate reservoir). The 1.6 TDI should be approached with more caution, especially if it's paired with the S tronic 7 gearbox (DQ200), whose erratic reliability can lead to exorbitant costs. Regardless of the engine, avoid examples that have been used exclusively in the city or whose maintenance history (especially DSG/S tronic gearbox oil changes) is incomplete.
