Notes on On-Board Diagnostic
An on-board diagnostic system with fault memory is integrated in the Tiptronic control module. It can detect and store certain faults on the electronic transmission control system. [1][2]Tiptronic System G40

If a fault is present it is first stored as a static fault. If the fault no longer exists it first becomes a sporadic fault and "Fault not present" appears in the display of the Tester. The counter is set to 40 in this case.

Sporadic faults are deleted automatically after 40 cold starts of the engine (followed by transmission warm-up).
