”Part number of basic control unit” to be entered: 1 429 884
- Enter the 17-digit vehicle identification number (WBA ……………) and confirm with ”Y” (yes).
- Enter ”Part number of programmed control unit” and confirm with ”Y” (yes). ”Part number of programmed control unit” to be entered: please refer to Service Information bulletin.

- Print out a new control unit label with the DIS and attach it to the control unit, next to the existing label. The old label should be crossed out to indicate it is no longer valid.
- Start the engine, and ensure it is turning over smoothly. Carry out a test drive so that the control unit can ”learn” the adaptation values. The idling speed may be slightly high during the adaptation phase, but it will soon return to normal.
- A ”Short test” must be conducted again via the diagnosis program. Stored faults should be deleted.
