Clar,
Thx for testing this! Who knew pumping exhaust into the cabin would be so controversial? (just trying to start a rumor... )
Everyone,
This is a great demonstration of how much people value choice. If no one knew about AS, we wouldn't have all these threads (because no one would notice. ) and if it were defeatable there would be no outrage. Just shut it off.
Ranters,
Rant on!

It's not 'pumping exhaust', or engine sound. It's an MP3 sound track. That's what bothers so many of us. Sound is one of the single most important features of a performance car. That's why aftermarket exhausts are the biggest dollar volume aftermarket item after wheels. If enough people 'rant', then BMW will at least make it switchable via Idrive. People who just accept whatever BMW does, don't do anything to improve the brand.

Eventually, somebody would have found out. "My stereo fuse blew, and my car is suddenly much quieter...".

I beg to differ on this. If you pay attention to the sound being pumped into the cabin via the speakers, it sounds nothing like the V8TT under the hood. It actually sounds like the whine of a V10. My theory on "Active Sound Design" is that BMW wanted to give the M5 an E60-inspired aural experience. I know some people will wholeheartedly disagree with me, but I don't see any other reason in using a V10 note, other than it being more "interesting/sporty" than the B8 under the hood.

I've brought this up on many YouTube videos (including the popular Autobahn clip:
). The sound you're hearing is a reproduction of a slighly-V10ish engine note. There is nothing V8 about it. Bring up some videos of V10 RS6 acceleration runs, and you'll hear what I mean.

I'm a hardcore BMW fan, and M cars have been my dream cars since I was a little boy. This, though, really doesn't sit well with me.

So what happens when you blow a speaker listening to too much Coolio? Will the engine sound like it is in a bag of newspaper?

If you open your windows you'll hear a louder more defined version of what gets played through the speakers.

The reason for the multilayered sound (why F10 M5 sounds unlike most V8s) is due to the cross-bank manifold and exhaust layout.

As Clar concluded, turn off the Active Sound & with the windows/sunroof closed, you'll just hear a muted version of what you go with Active Sound.

Can AS be coded out?

I can't imagine why they wouldn't make this a feature in which the driver could enable/disable..???????

I realize that, but since the sound is "amplified" by the stereo/speakers, what happens if a speaker is blown? Will the AS sound like garbage? It was more of a facetious question, but I'm still curious.

BMW: "Oh, you are outside of warranty and blew a speaker? Sorry that your engine now sounds like garbage."

ASD disabled in M5

Hi folks
Finally I was able to disable ASD by just unplugging the ASD connector cable from the ASD Sound Module. It takes about One hour and there are no impacts/errors. I have a Hamann exhaust installed and ist sounds really great. Hence I dont need any fake sound in the cabin. It's way too loud with ASD
For details let me know.

The active sound would be the least I'd worry about on an M5 outside of warranty... (and hopefully by the time the speaker blows due to blasting music at full volume, hearing will be impaired to the point that active sound is no longer noticeable, so problem fixed ).

Plenty of manufacturers doing active sound, not just BMW and not the only thing that will be fun to live with on out of warranty cars...

Silverxy-

Where is the module located? Can you provide some instructions?

Thanks!

Ha. Truth.

Although I've got a 2015 STi on order and instead of amplifying the engine note, they use a sound tube (or something similar) to direct the direct noise in to the cabin, instead of synthesizing whatever engine frequencies are deemed beneficial. I'm not OK with ASD, but I'm more OK with redirected notes…

See the pics.

Turn down the back seat. You have to remove the covers on the floor (the big one) and the left one. You also have to lift the rubber seal a little beat so that you can remove the backplane.

Almost everything is fixed with press buttons which you can remove safely. Finally you can use them again to put everything together.

After you remove the left cover you have access to the ASD module. Just unplug the connector and fix it with a cable strap.

We're currently working on a switch/button to enable/disable ASD from the rear trunk

ASD with the original exhust is fine. But with the Hamann it's that loud that it isn't fun anymore! However I think BMW should make this feature configurable in the iDRIVE.

I too have just had my Active Sound Module disconnected by the stereo shop which is just completing an over-the-top sound system for me (i.e. I wasn't 100% satisfied with the B&O I ordered). Secondarily, with my M Performance (Akrapovic) exhaust, I thought it wise for both these reasons to do away with Active Exhaust Sound, etc.

Is the audio (CD/radio) still working with the ASD disconnected?
Mine is M135i which also has ASD.

Yes. The cable is for ASD only. No impact to Radio!
