Search the fault memory via ”Short test” – process any faults stored – finally clear the fault memory with ”Quick delete” – no faults must be stored in the control units which are to be programmed.
The battery must be sufficiently charged – install a charger before commencing programming.
Load BMW Software with the current programming software (CD V 59.0 or later).

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 The old label should be crossed out to indicate it is no longer valid.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.
