From December 2001
On Board Diagnostics (OBD), From 12.01
OBD program text/data generated by control modules installed on vehicles from 12.01 production may not be recognized by VAG 1551/1552 Scan
Tools (ST) with the latest program card. For example: scan tool display shows "text 799", "01529/references" or similar.
Only the VAS 5051/5052 Vehicle Diagnostic Testing and Information System is capable of processing all display text/data on these vehicles.
OBD program functions on vehicles from 12.01 production must be performed using the VAS 5051 Vehicle Diagnostic Testing and
Information System in mode "Guided Fault Finding".
