What does this mean in the workshop?
Module 46 supports replacement of VGS4-0-NAG2 (4-4) through preparation and personalisation-data transfer. A separate licence is available for Module 16 owners, subject to checking their existing adapters.
Data transfer is useful when replacing a supported controller. It does not repair a hardware fault or make different hardware versions interchangeable. Compare both controller identifiers and retain the original backup before service work.
Application scope
- Data reading and transfer when replacing a compatible controller.
- Preparation of a supported module for vehicle readaptation.

Before ordering
This is an ACDP expansion, not the base programmer. Operation requires a compatible host, the appropriate interface and an activated licence for the selected function. We check your existing equipment and the additions required before ordering.
Compatibility review
Send the vehicle model and year, ECU, TCU or IMMO identifier, required function and the serial number of your existing ACDP unit. Support depends on the specific controller, hardware and activated authorisations; the vehicle brand alone does not establish compatibility.
