Disclaimer:
A compatible diagnostic interface is required and is not included unless clearly stated separately. Vehicle coverage, functions, coding options, service procedures, and live data availability depend on the exact vehicle model, production year, ECU type, market, interface quality, driver compatibility, and Windows setup. Always use diagnostic and programming functions carefully and keep a stable battery power supply connected when performing service routines, coding, adaptation, or flashing operations.
