Before the Volkswagen Group's ODIS Service software, VAS-PC was used on workshop diagnostic computers. Volkswagen's service documentation identifies VAS-PC software on VAS 5051B equipment and shows it on a VAS 6160-VPC portable diagnostic system.

VAS 5052
Volkswagen's equipment catalogue dates introduction of the VAS 5052 vehicle diagnostic and service information system to autumn 2001, with diagnostic leads and optional adapters. The VAS number denotes equipment, while VAS-PC denotes a software generation; a particular tester's capabilities depend on its software and configuration. Volkswagen VAS 5052 equipment catalogue.
Transition to ODIS
A Volkswagen of America service announcement describes the June 2012 ODIS Service rollout and the planned replacement of VAS-PC. Treat this as a regional software transition, not a universal vehicle-year cutoff. Volkswagen VAS-PC end-of-life announcement.
