Self Study Program 294 – VAS 5051 on-line link

VAG SSP 294. To date, the diagnosis system VAS 5051 only permitted communication with the vehicle. The on-line link extends the potential offered by the tester. To coincide with the market launch of the Audi A8 2003, two on-line functions are available for the diagnosis tester. Firstly, telediagnosis which permits remote control of the tester from another location.

Secondly, the diagnosis tester link to a central data base.

Fully automatic adaption of the immobilizer components is effected by means of direct communication between data base and tester.

This facilitates the procedure when replacing such components in the vehicle and also further enhances system reliability.
