SERVICE INFORMATION
This Service Information Bulletin (Revision 1) replaces SI B64 07 21 dated August 2021.
What's New (Specific text highlighted):
- ISTA SW version that contains the software
SITUATION
Only warm air comes out of the vents despite the air conditioning being switched on. The status indicator LED on the air conditioning control panel (IHKA) lights up green. No related fault codes are stored in the IHKA.
CAUSE
Faulty parameters in the IHKA control unit.
CORRECTION
Diagnose the air conditioning system. If no related faults are found, program the vehicle with ISTA 4.31.3 (released September 23, 2021) to I-Level S15A-21-07-540 or higher. Replacement of the IHKA control panel is not necessary.
PROCEDURE
Determine the vehicle's current I-level by either using AIR or the ISPA NEXT application.
Perform a vehicle test and check for any related IHKA fault codes.
If no relevant faults are stored, program the vehicle with ISTA 4.31.3 to Integration Level S15A-21-07-540 or higher.
Note that ISTA will automatically reprogram and code all programmable control modules that do not have the latest software.
Always connect a BMW-approved battery charger/power supply ( SI B04 23 10 ) when performing programming.
For information on programming and coding with ISTA, refer to DealerSpeed/TIS/Technical Documentation/Diagnostics and Programming/Programming Documentation.
PARTS INFORMATION
Replacement of the IHKA control panel is not necessary.

Select one of these open Technical Campaigns to perform and submit for updating the vehicle's software to the required I-level or higher.
Please be sure to perform any additional before and/or after work (including attaching labels) as required by the open campaigns on the vehicle. Close any remaining open programming and encoding Campaign repairs as outlined in the corresponding Service Information Bulletin.
