Hi everyone! Recently, I left my 2011 MCS powered off for quite a while to do some work on it, and with the battery being very weak, when I turned the ignition on, somehow the car started acting up, playing the standard LCI Mini chimes followed by an E90 LCI BMW chime.

I have an aftermarket Sony headunit with an Axxess chime retention box, so somehow the LCI E90 gong must be stored in the box or the car...
I have set HU_VERBAUT in KOMBI with NCS Expert from the default radiostuffe_3_4 to radiostuffe_1 and radiostuffe_2, which gave a very different piezo-sounding, buzzer sound.

Any ideas how to possibly integrate this LCI E90 gong which seems to be stored in the car / chime retention box? Good nostalgia from when I owned an E90!

Thanks!!
