Hi,
I know there is many posts about this, but I didn't found my answer in the ones that already exists.
I own a 2013 M135i xDrive and like many others, I did want to get the "true sound" of my car, not the artificial sound generated by ASD (active sound design).
So I purchased the Bimmercode android app and with my ELM.327 bluetooth adapter, i coded it to "off"
I noticed a difference, but it was very slight so, for compare, I disconnected the module in my trunk (I know I lose the audio system with this, but it was just for compare). With this module disconnected, it was exactly the same as with ASD codded "off" with Bimmercode.
So I think it's really disabled but, just for be sure:
- Is the module I disconnected (see picture
https://ibb.co/gEZcUe) really the ASD? Didn't I disconnect something else that would explain why I don't hear so much difference?
- Even with ASD turned off with Bimmercode (or with module disconnected in the trunk) I got some "bass sound" from the rear in mode "Sport" when I downshift. I don't have it in "comfort" mode, only in "sport". You will say me it's sport mode, so it's normal, ye, but I want to be sure this sound is genuine and can be heard from the outside too... So I wonder what cause this sound in Sport mode if it's not the ASD speakers? Because sports mode don't do something else, my exhaust system already have the valve always open (fuse Number 146 removed) so what could cause this difference in sports mode? I don't think sport mode change something else compared to comfort mode so, if I hear a difference, it makes me think the ASD is still not completely disabled, even with the module disconnected...
Thanks for your answers :-)
