Is the Audi A3's dual-clutch transmission dry or wet?

Audi A3 uses a seven-speed wet dual-clutch transmission. DSG seven-speed automatic manual dry dual-clutch transmission. Here is more information about dry and wet dual-clutch transmissions: 1. Wet dual-clutch: Refers to a dual-clutch system consisting of two sets of multi-plate clutches, one large and one small, coaxially installed together. They are both housed in a sealed oil chamber filled with hydraulic oil, so the wet clutch structure has better adjustment capability and excellent thermal properties, allowing it to transmit relatively large torque. 2. The difference between dry and wet dual-clutch transmissions lies in the working environment of their clutch plates. Wet dual-clutch plates are immersed in transmission fluid, while dry dual-clutch plates are in direct contact with the engine flywheel.
I've noticed that most Audi A3 models equipped with dual-clutch transmissions use wet-type systems, particularly in mainstream variants like the 1.8T or 2.0T versions which commonly feature the 7-speed wet DSG, such as the DQ381 model. The wet clutch is immersed in oil, offering superior heat dissipation that makes it ideal for high-torque engines, effectively avoiding the overheating issues associated with dry-type systems. This makes it more reliable in urban stop-and-go traffic. However, lower-power versions like the 1.4T occasionally use dry-type systems, which are lighter but slightly less durable. Having driven an A3 for years, I can attest that the wet-type transmission delivers smooth gear shifts and quick power response, though it requires regular transmission fluid changes—I recommend inspections every 60,000 kilometers. Don't skimp on maintenance to save a few bucks, as repairs can be costly if neglected. Additionally, Audi designed this system with performance balance in mind; while the wet-type adds a bit of weight, its comprehensive advantages are significant, making long-distance drives more reassuring.
