Hello everyone About 2 months ago my MIB1 MMI (5Q0035840A) kicked the bucket and I decided to upgrade it to a MIB2 Amundsen. I bought the 5Q0035874A Amundsen MIB2 and the 5E0919606 8 inch Columbus screen, got the component protection removed and there was no sound. Not knowing I had to also swap out the Canton amplifier for a MIB2 one, I gave up on it and bought a working original MMI. The problem now is that even with the original MMI there is still no sound after component protection removal. OBD scan gave me the following fault codes: Left front bass speaker - Fault code B105F13 Right rear bass speaker - Fault code B106713 Right rear treble speaker - Fault code B106813 Left rear treble speaker - Fault code B106613 Left front treble speaker - Fault code B106113 Left rear bass speaker - Fault code B106513 Right front treble speaker - Fault code B106413 Right front bass speaker Fault code B106213 Now I'm debating on whether I should stick with the original MMI or get a MIB2 amplifier in hopes that after component protection removal the speakers will start working again.
