The 7-speed DSG transmission DQ381 and the DQ500 (0GC / 0DL) with Bosch control unit from VW, which was used in many vehicles of the VAG Group, is an electronically controlled dual-clutch transmission.

The DQ381/ DQ500 uses a wet clutch. This type of clutch is immersed in oil, which allows for better cooling and a longer service life. The DQ381/ DQ500 is designed for a maximum torque transmission of up to 420/ 600 Nm, making it suitable for a wide range of engines, including powerful variants such as the VW Golf R.
Once the DQ381/ DQ500 has been tested and repaired by us, the basic setting must be carried out using a diagnostic tester after installation.
