What is the VW DQ500?

The DQ500 is a 7-speed wet dual-clutch DSG gearbox fitted to higher torque VW Tiguan, VW Transporter T6 and other VAG group vehicles. It is a heavier duty variant of the DSG family designed for larger engines and all-wheel drive applications. The mechatronic unit controls all gearbox functions including both wet clutch packs, gear shift actuation and hydraulic pressure — and shares the same internal failure patterns as the DQ381 and DQ380.

Our full mechatronic repair and cloning service covers all DQ500 variants. See our VW mechatronic repair page and our VW DQ381 fault page for full VW DSG coverage.
