The OBDSTAR TCM-005 connects a 16-pin TCM connector on the vehicle side to a 15-pin DB15 connector on the device side. The cable is designed for Bosch TCM control modules of the DQ380 (0DE), DQ381 (0GC), and DQ500 type, whose connector sits directly on the transmission housing.
These are seven-speed wet-plate DSG transmissions used in high-performance models and heavy-duty variants within the Volkswagen Group. This cable provides direct access to the transmission control module, bypassing the OBD2 port entirely. This approach is intended for operations where standard OBD2 communication doesn't provide sufficient access, such as reading or reprogramming TCM data on MQB and MLB platform vehicles.
The cable establishes a hardware-level connection; the actual operations depend on your programming software. Note the market difference: the DQ380 (0DE) is primarily intended for the Chinese and Asian markets and is rarely found in Europe. The model list below shows the transmission type and production years for each model.
KEY BENEFITS
IMPORTANT NOTES
Applications and Functions
When used with OBDSTAR equipment, the cable supports the following operations on the Bosch transmission control module.
Control units you can access
- Bosch TCM (DQ380, DQ381, DQ500): directly connected via the 16-pin connector on the transmission housing.
- No other control units: the cable connects directly to the transmission control module, bypassing the OBD2 port.
What you can do
- Read TCM data: retrieve current programming data from the control module via the direct 16-pin connection.
- Write TCM data: rewrite or update software and calibration parameters through the DB15 interface.
- Identify the transmission: query the software version and hardware identification of the DQ380, DQ381 or DQ500.
- Work at hardware level: perform operations that are unavailable or limited through the standard OBD2 interface.
- Important: first determine which transmission type is installed in your vehicle; DQ380, DQ381 and DQ500 units can be mixed within the same model name.
Compatible vehicles and applications
What matters is the Bosch control unit for the DQ380, DQ381 or DQ500 with 16-pin TCM connector, not the vehicle model. The vehicles listed below are equipped with these transmissions, with the transmission type specified for each model. Only confirmed models and production years are included.
