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.
