Fake interior engine rpm sound
Does the FL MY2019+ AMG C63S have an interior engine sound generator through the sound system? I know they’ve introduced it on certain C43s.

As a matter of fact, if you search for part number: A2059005330 you might be surprised to find that the FACELIFT 205 C63s has an ENGINE SOUND GENERATOR

I’ve got a 2020 on order. I’m not interested in having a sound generator as I agree the V8 sounds great by itself. Any way to disable? I went into the harness on my F150 and pulled 2 pins to eliminate it, but I would image the Germans have made it more difficult!

Yes the facelift cars pump in sound for sure. I know because I have the ASR module that keeps my exhausts always 100% open.
The PE button technically should no longer do anything, but that is not actually the case. AMG hides it in a pretty clever way. I don't think it activates at idle or even low speed.
On the highway it is very obvious. Leave PE off and you hear natural exhaust noise. Turn on the PE and suddenly you'll hear an increased bassy engine noise and volume.
I will say though, I kind of understand why AMG added it. This car is quiet on the inside even with valves 100% open as the sound deadening is excellent.

There is no such part number A2059005330 ENGINE SOUND GENERATOR for prefacelift C63s or any type of fake "Sound generator" parts. Just triple checked the Mercedes EPC (Electronic Parts Catalogue).
I can also confirm that the only cars that have "fake" engine sounds and contain this module 230 are:
Facelift C63 AMG
GLC 63 AMG
GLC 43 AMG
C43 AMG
C450
Rest assured, the C63 and C63s prefacelift DO NOT have artificial sound generators or any such module in our cars.

I may be wrong, but from what I've read I believe the PE button also controls the H valve, which the ASR module doesn't have anything to do with. So when you turn the button on and off, while nothing is changing with the valves at the mufflers, other things are still responding.

My research (via WIS) says that you can look at the build sheet for the vehicle and, if it has "Sporty Engine Sound: code B63" then it has the digital signal processor module (DSP) that seems to be used for 2 purposes:
- adding fake/"sporty" engine sound into the cabin via the sound-system speakers (for me, a definite "will not buy such a car" unless it can be disabled "[non]feature")
- adding noise-cancelling sound into the cabin via the sound-system speakers ... haven't looked up various models, but I suspect this is for the S-class and Maybach vehicles to actually mute any engine/outside noise that enters the cabin
- adding fake/"sporty" engine sound into the cabin via the sound-system speakers (for me, a definite "will not buy such a car" unless it can be disabled "[non]feature")

I think one should differentiate between fake engine noise as in synthesized, artificial engine sound played into the cabin via speakers, hello BMW and enhanced sound as in the real engine/exhaust sound and vibrations pipe into the cabin through mechanical means. I'm not ruling out that the C63 does the latter. The thing is these cars have a lot of sound insulation to keep unwanted noise out of the cabin. I sometimes start my car with the windows or door open in my garage and it makes it very obvious just how much sound deadening there is. Unfortunately, this also keeps the stuff out that we do want to hear, so piping it in makes a lot of sense, as long as it is the real sound. The C63S also has dynamic engine mounts, which allow it to absorb engine vibration for if so desired for comfort, but the result is a looser front end, or mount the engine tightly to the chassis in the sportier modes for a sharper responding front end, but also transferring engine vibration to the cabin. I think this is all good stuff. The all-new A45 definitely uses a system that somehow pipes the real sound and vibration of the engine/exhaust into the cabin as revealed by a recent interview. I think AMG understands that we don't want to listen to a WAV file.

I have contacted AMG Sydney and AMG Germany (as this has really concerned me).
Is this information right?

I'm pretty sure there is no artificial sounds because in cutting out my secondary cats the characteristic and volume of the sound completely changed, and that can be heard from inside the cabin. If there was artificial sound, I wouldn't be able to hear a difference from within the cabin.

Yes it reacts to the throttle but I believe the PE button tells it how to react to the throttle.

Difference could be attributed to load on the engine.

At highway speeds there is enough load on the engine that when the exhaust button is on, the valve will open. If you turn it off, it closes.
ASR has nothing to do with H valve.

I know that my 2017 C43 sedan does not have code B63.
I'd not even thought of that, I was only thinking of the fake/synthesized sound through speakers. I'm not opposed to selective (even gated) means of "letting the real outside engine/exhaust sound into the inside" ... in fact, on the track, I fold down the rear seatbacks -- you know, for lower center of gravity and better handling ... OK, really for the increased (glorious) exhaust-note volume! #;-)

Tested on a range of engine loads. Heard the increased noise most clearly at moderate throttle when PE on. No increase in noise at the same throttle with PE off.
Right, ASR has nothing to do with the H-valve. And I don't think the PE button does either. Look at page 5 of this very thread.

I think the question you have to ask yourself is how much of a real purist are you. Do you like fake ***** or prefer the all natural type? I mean, if you don't want "enhanced" engine noise in your car (you know...that fake "sporty" sound) then I assume you also don't go for fake, sporty, D-cups either, right? Or are you OK with certain kinds of "fake" but not others. Personally, I think the car sounds great no matter how they do it, and I don't really care how they do it. But then I like ***** in almost all shapes and sizes, so maybe I'm just easy to please.

I agree with you that there’s synthetic sound as I tested with a microphone near speakers.

Mail from AMG Germany after inquiring about purchasing a 2020 C63s Coupe locally and asking them about the Sound Generator in the C63s:
Herr Lisciandro,
Ich habe mit der technischen Abteilung über die Motorgeräuschfunktion des aufgefrischten Mercedes-Benz C 63 AMG S Coupé gesprochen.
Wir können bestätigen, dass diese Besonderheit ausgestattet sein muss.
Der Soundgenerator ist für das neu bestellte Mercedes-AMG C 63 S Coupé, die Limousine, den Kombi und das Cabriolet mit dem Ziel der Verbesserung des Cockpits und des Cockpits außerhalb des Cockpits vorgesehen. Dies ist keine optionale Ausstattung, sondern eine neue Standardfunktion, die den Induktionsklang und die Spielstärke verbessert.
Selbstverständlich beantworten wir auch gerne Ihre Fragen.

Topics on FL sound need to close already. If youre all about a refreshed interior, the FL will be better for you but if you are looking for that AMG brutality I feel like the FL is taking a step back. Choose your poison.

Here's a good article that puts some of this in perspective. We are definitely experiencing the end of an era, and in all likelihood performance cars as we know them will be a thing of the past. It's costing these manufacturers tons of money to meet all these new requirements, so don't expect them to cater to other markets that don't have the same strict regulations. The only manufacturers that get away with doing things mostly the old way are very low volume production outfits that sell less than 10,000 cars a year.

Has anyone noticed that when you have the PE exhaust on, the sound quality of your music deteriorates due to increased bass? I have a 2020 that I took delivery of in November, and the bass is awful. Wondering if it is related to the PE exhaust, if I just need to let speakers break in, or if I am having a one-off problem that I need to sort with the dealer.
