In german it just means radio level but I'm not sure? Have you heard of anyone with this form of problem?
If you have old style chime, it is not enough changing the KOMBI code, you have to change the Head Unit with one newer (from 09/07 or after)
I don't know if it is possible to flash your current HU and install a new firmware.
If you don't have neither bluetooth nor USB you better buy one with them built-in like mine.
