CAUSE
The IHKA operating software is too sensitive.
PROCEDURE
DO NOT replace parts!
Perform a conversion with ISTA/P "Deactivation of the automatic air recirculation control".
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software. For information on programming and coding with ISTA/P, refer to CenterNet / TIS / Technical Documentation / Programming and Diagnostics / ISTA/P Documentation.
Always connect a BMW approved battery charger / power supply (SI B 04 23 10 ).
The final report shows the VO modified with K-Word "DAUE". The air recirculation button will function in manual mode only.
