Dual-clutch transmission records
Volkswagen Group uses DQ designations for particular DSG dual-clutch gearbox families. Its training material identifies DQ381 and DQ500 examples and describes the mechatronic control of the clutches. The Bosch catalogue contains the following separately imported gearbox and control-unit labels:
- Bosch DQ380
- Bosch DQ381
- Bosch DQ381 Gen2
- Bosch DQ381.g1
- Bosch DQ381.g2
- Bosch DQ500 (MQB)
- Bosch DQ500 Gen2
- Bosch DQ500.g3
Browse Bosch → Transmissions → DCT. A shared gearbox designation does not by itself identify the controller manufacturer, exact hardware or compatible software. Some labels overlap and require further source-specific review.
