New OBD protocols for Marelli IAW 4LV – Audi, Volkswagen, Seat and Skoda.

With this release, we introduce new OBD protocols for Marelli IAW 4LV ECUs, a key reference in the European B/C segment and still widely used today in the South American market.

These protocols cover 1.0 and 1.4 MPI engines, produced from 1998 to the early 2000s: long-lasting, reliable, and still regularly serviced in workshops.

Thanks to OBD communication, you can work quickly and directly, without disassembly, optimizing time and workflow.

A release that turns technical simplicity into an operational advantage: read and write via the diagnostic port, manage high workloads, and make every job faster, more efficient, and more profitable.
