DFOX TCU VAG DQ250 Cable 6EACBB02

The DFOX TCU VAG DQ250 Cable (6EACBB02) is a specialized adapter cable used in automotive transmission diagnostics and programming — specifically for VAG Group (Volkswagen, Audi, Škoda, SEAT) DSG DQ250 6‑speed transmission control units (TCU).

• It connects a DFOX diagnostic/programming tool to the TCU of a VAG DQ250 DSG gearbox.
• This allows technicians to read and write TCU data, perform software updates / reflashing, clone TCUs, and do other advanced transmission diagnostics.
• Such cables are essential when working on the TCU outside the car (“bench mode”) or when doing deep tuning, cloning, or recovery work that goes beyond simple OBD‑only communication.

Typical Use Cases

✔ Automotive repair shops and tuners working on DSG transmissions
✔ Cloning or reflashing a DQ250 TCU
✔ Bench programming (working on the unit out of the vehicle)
✔ Advanced diagnostics or tuning beyond standard OBD tools

Compatibility

The cable is meant for VAG Group cars equipped with the 6‑speed DSG DQ250 transmission (various VW, Audi, SEAT, Škoda models).
