I want to either turn off or turn down the fake exhaust Soundakator sound in my S4, and found this VCDS tip on one of the Audi forums:

"A9 Structure Borne Sound
Adaptation 10
At Channel drop down choose “Volume of structure borne noise actuator” (only choice)
Enter a value in the proper box (0% = mute )"

However, I can't seem to find the choice of " A9 Structure Borne Sound".
Can someone direct me to the proper module?

Thank you!

Hmm, I'm looking at an Auto-Scan from a B8.5 S4, and it has:

Code:
Address A9: Struct. Borne Sound (J869)       Labels: 4H0-907-159.clb
   Part No SW: 8K0 907 159     HW: 4H0 907 159 A
   Component: SAS-GEN 2     H06 0006
Mind posting an Auto-Scan from your car?

That's probably from mine :) Had no trouble shutting the bleeping thing off a long time ago:
Code:
;SW:8K0-907-159   HW:4H0-907-159-A ---  Struct. Borne Sound
;Component:SAS-GEN 2     H06 0006, Coding:
;EV_SoundActuaGen2AU64X,003010,EV_SoundActuaGen2AU64X.rod

Thanks for responding Uwe/Eric-

I'm at work so I can't until tonight. I never thought to look at all the readouts of modules when doing the auto-scan, so how would I open up that module to change the coding? Would I find it under the "Select control Modules" section on the Main screen?

Thanks again!

Yep. :cool:

Yes. Control modules on the Installed tab are in (hexadecimal) numeric order. Depending on how much stuff you car has in it, there may be a second "Installed" tab.

Or, if you're old-school, you could just type A9 into the Direct Entry box at the bottom and click [Go!]

Awesome, thanks, I will do this tonight and post my outcome.

So I went in and changed the value to 0.0, and when I clicked "do it", I got this message:



It caught me by surprise since no one mentioned a warning message, so I closed out without making the changes, since I was not sure what it meant or how to respond?

Thanks, but now still not clear which choice I should pick? It says you should choose "yes" and let it add 12345/1234/1234...
I would try that first. The module may or may not accept it. If it doesn't, then you'll have to use more random non-zero numbers.

Thanks again, I just didn't want to really mess something up. I will try it this weekend and see how it goes.

Oh it sounds great, fairly throaty... I have limited experience hearing assorted cars other than 4-cyl (and mostly diesels!, from when I interned at a dealership in France), but I don't think it really sounds like a supercharged V6. Without the soundaktor you can actually hear the supercharger a little, and the more subdued/less macho sound goads you less into involuntarily speeding (important when you have 400+HP on tap). Then I get in Uwe's A6 and wonder why it's so damn loud compared to the S4... oh right, we didn't turn that one down :)

Unless I'm missing something in the scans from that car, there isn't anything to turn down in that car -- i.e. the sound in that one is all real. :p

Update: Finally got around to trying this again. Just has to click "Yes" to accepting values and it worked. Glad to get rid of that fake sound.

I thought it odd that mine sounded louder in 'S' than in 'D' with the extra noise sounding wrong. Then I found out there was a speaker playing fake engine noise, I disabled it (set % to 0) as soon as I found out how to do so, actually I pulled the fuse out first because that was easier to do but my OCD didn't like the errors that threw up on an autoscan, but it sounds much better without it, I really think the whole 'soundaktor' think is naff beyond belief...

I concur.

But I suspect it's become increasingly difficult to engineer intake and exhaust systems that sound pleasing in the cabin while still meeting all the other applicable regulations (exterior noise, emissions, and efficiency), and the Soundaktor is relatively easy work-around.

I still don't like them. :p
