Maybe not 100% ontopic but I have an issue with my IHKA3:
Car is from 03/14 but IHKA3 was already there. So I retrofitted LCI HVAC and everything was working properly. I tested all functions / buttons for 2 mins and then turned the panel off.
Afterwards I coded IHKA3 with „Fatbumschlag“ to get the color change from white to amber. After coding the panel turned on, everything is still working but I cant switch it off anymore. I can go to lowest ventilation setting and if I keep pressing the lower / off button further nothing happens.
Anybody has an idea what went wrong? Coding was done with e-sys, VCM readout first and the only value changed was „Farbumschlag“ before FDL coding it
