M4 ASD sound on N20
Hi guys, I have a 2016 428i F33 M Sport and id like to code my ASD to have the M4 sound instead of the N20. Now I've tried doing this via BimmerCode, but once I do it actually turns ASD completely off. I have read forums mentioning that I need to downgrade the firmware of the ASD module. Can someone show me how this might be done?
I'm happy to also pay someone to get this service done for me!
