The mystery of the Acoustic Simulator module - what the hell does this do??

[Kayone73]

So for context, when I ordered my car and the build was complete out of the factory, I was able to look up the VIN and see there were a couple minor missing components thanks to the global parts shortage:

Fortunately neither components (phone charging pad or acoustic Simulator module) would affect delivery of my car or result in a stop sale. However I wondered what the Acoustic Simulator module was and best guess it had to do with controlling the Sport Sound (which I optioned) so I thought worst case my Sport Sound wouldn't work properly when I took delivery. Again no big deal I guess.

But when I did take delivery, my Sport Sound seemed to work normally which only raised more questions what the purpose of the missing Acoustic component was for. Then eventually I was able to get both missing components retrofit at a local dealership service dept and....still no real difference with the Electronic Sport Sound or any other obvious sound related function in my car.

So the mystery only continues to deepen what the heck the Acoustic Simulator Module actually does

Could it be the external noise?

Good guess but even before the retrofit, the car had external noise as well? Maybe it's now a little louder? It's not obviously so and without some objective way to measure the sound levels before and after I have no way to prove it scientifically.

See the NHTSA doc for WMG6. It’s the electric sport sound generation for the interior.
Most likely what you were hearing before the retrofit, was the actual sound of the car without supplemental audio, or that plus whatever additional sound that gets piped externally for warning pedestrians.

Unfortunately while what you're saying SHOULD be correct, I had a few months to drive this car before I could get the retrofit done, I was getting internal sound piped in thru the internal speakers like you described AND external sound confirmed by people outside of the car.

I cannot tell any real difference in either inside or out after the retrofit was done. So clearly I'm missing something.

Sport Sound only works if you put the car in Sport/Sport Plus mode or turn it on through the menus. Have you tested with these settings?

That's not true, even prior to the retrofit I could manually activate Sport Sound in Range or Normal mode on the main infotainment screen. I mapped the function to the programmable diamond button on my steering wheel and could turn it on in non Sport/Sport Plus mode prior to the retrofit.

That’s what I meant when I said “or turn it on through the menus”.

Sorry your phrasing is kind of confusing. Hard to parse out exactly what you're trying to say.

Might it be that you were missing one of the outside speakers? There are speakers both front and rear. This would then explain why you experienced the sportsound both before and after they installed the missing component.

That is possible. I really don't know what is all the hardware involved in Sport Sound production and sound system.

External speakers in the front and rear, as well as a pair of speakers in the rear doors for internal sound. And a dedicated amplifier for these four speakers, that seems to be installed in the passenger side of the trunk.

EDIT: Found a picture to illustrate.

Thanks for the info! Can you explain how you found those open campaigns with you VIN? Or how to find any other stop sale items associated with that particular VIN? Thanks in advance!!

Someone else in this forums works for Porsche Parts Dept at a dealership and had access to their internal tracking system and sent me a screenshot.

This info is something normally not directly accessible to customers and we have to bug our SAs for this info.

DerekS on this forum found the retrofit manual for this a while back it seems, as it came up now when googling some partnumbers related to the acoustic simulator.

And it does seem to have a small'ish controle module...that I wasnt able to find in the partscatalogue... This is probable what your car was missing...
