Important information regarding compatibility

The range of diagnostic functions, active tests, resets, adaptations, and service procedures depends on the brand, model, year, engine version, target market, equipment, and controllers used.

Not every listed function is available in every car. We recommend checking compatibility based on the exact model, year, engine version, and VIN before purchase.

Functions related to the immobilizer, odometer, airbags, high-voltage systems, radar, and cameras may only be available in selected vehicles and controllers.

The device does not replace factory diagnostic systems in terms of online controller programming, firmware updates, online coding, component protection, or operations requiring access to the manufacturer's servers.

All actions related to odometer indication must be performed in accordance with applicable regulations and for the purpose of legal repair or replacement of components.
