Its expanded MQB platform support and additional PCF7939 compatibility make it the definitive solution for modern automotive security systems.
XT57B is recommended for:
Technicians servicing newer European vehicles
Shops encountering MQB platform vehicles
Professionals seeking maximum compatibility
Future-proofing your diagnostic toolkit
