SUBJECT

IHKA - Recirculation Function Changes from Manual to Automatic 

SITUATION

While driving, the air recirculation button on IHKA changes by itself from manual to automatic or automatic to manual mode.

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.
