Exact compatibility depends on the TCU part number, hardware/software revision, transmission code, and vehicle application.

How It Works

1. Purchase the service.
2. Mail us your original DQ381 TCU and a compatible replacement TCU.
3. We read and back up the required data from your original controller.
4. The necessary programming and vehicle-specific data is transferred to the replacement.
5. We bench verify the cloned TCU and return both units to you.

What You Need to Send

• Original DQ381 TCU
• Compatible replacement/donor DQ381 TCU

For the best compatibility, we recommend matching the VAG part number, manufacturer number, hardware revision, transmission code, and TCU version as closely as possible.

If you're unsure whether your replacement TCU is compatible, send us clear pictures of the identifying information from both units before shipping and we can help check compatibility.

Failed or Non-Communicating Original TCU?

A failed or non-communicating TCU may still contain recoverable programming data. We can attempt to retrieve the required information using bench or direct programming methods.

If the original controller is too severely damaged to recover the data required for cloning, we will contact you before proceeding.

Important

This listing is for TCU cloning/programming only unless a replacement module is specifically included with your order. It does not include repair of clutch packs, actuators, hydraulic components, mechatronic hardware, wiring, or other mechanical transmission faults.
