Control unit was replaced./Programming based on instructions from ISTA diagnosis./Programming due to Technical Campaign.
Control unit was replaced.
With the introduction of ISTA 4, the programming functionality was integrated into ISTA.
- The following series can be treated with ISTA/P: Exx series and RR1, RR2, RR3
- The following series can be treated with ISTA 4: Fxx, Gxx, Ixx series and following
To avoid errors during programming/coding, the current ISTA/P or ISTA 4 version must be used.
For programming, the programming data must also be installed for ISTA 4.
Battery voltage must not drop below 13.0 V during programming. Only use battery chargers recommended by BMW for low-voltage vehicle electrical systems.
- Programming with ISTA P:
Connect the battery charger to the vehicle.
Connect the programming system with the vehicle.
Connect the ICOM vehicle interface to the workshop network via a LAN cable. Check cable routing (do not route cables through open side windows).
Turn on the ignition or activate testing-analysis-diagnosis (PAD) before connecting the ICOM vehicle interface to the vehicle.
Start ISTA session.
Determine the action plan.
Accept and fully process the action plan.
Wait until programming/coding has been completed.
Depending on the reworking list, carry out an ISTA diagnosis session if necessary.
Disconnect the programming system from the vehicle.
Disconnect the battery charger from the vehicle.

Reset ultra-small quantity adaptation
NOTE: TECHNICAL INFORMATION
If the DME control unit or an injector is replaced, minimum quantity adaptation must be reset. If an injector has been replaced on cylinder side, the minimum quantity adaptation must also be reset. - Connect the diagnostic system and reset the minimum quantity adaptation:
- Read out vehicle data
- Identification with vehicle test
- Start vehicle test
- Vehicle handling
- Service functions
- Drive
- Engine electronics
- Reset adaptation values
- Fuel system adaptation values
- Continue service function
