Would taking the radio out of the equation help then? Has anyone completely killed the radio speakers (taken the fuse out) to rule out any sound enhancement?
I know a lot has been discussed in this thread about pre-FL vs FL C43 with and without PE. Not to derail the thread, but was just curious if anyone knows if the same is true with C63 as well, i.e. no piped in sound and no corresponding fuse for the sound generator?
FL means "facelift" which happened with model year 2019 and included front and rear valance updates, additional power and torque and numerous other design and tech changes. If '18, then it's a pre-FL.

He knows what facelift is , he means he doesn't know re the sound through speakers on the facelift .

The same applies to the C63:
Facelift with PE: Sound-Enhanced
Facelift without PE: Sound-Enhanced
Non-Facelift with PE: Sound-Enhanced
Non-Facelift without PE: NO Sound-Enhancing
Mail from AMG Germany asking them about the Sound-Generator in the C63s: Gerne habe ich hinsichtlich der Motorsound Funktion im Mercedes-Benz C 63 AMG S Coupe mit der technischen Fachabteilung gesprochen.
Bei der Funktion handelt es sich um eine Sonderausstattung, mit der das Fahrzeug ausgestattet sein muss. Da mir keine Fahrzeugidentnummer vorliegt, können wir die Ausstattung nicht prüfen und dementsprechend keine genauen Angaben machen. Gerne gehen wir Ihrer Anfrage nochmals genau nach, wenn Sie mir eine Kopie der Zulassungspapiere zukommen lassen.
Natürlich sind wir auch bei Fragen darüber hinaus gerne wieder für Sie da.
And then the second Mail:
hiermit komme ich zurück auf Ihre Antwort.
In Bezug auf die Motorsound Funktion habe ich nochmals mit meinen Kollegen Rücksprache gehalten.
Der Soundgenerator, mit der Teilenummer A 205 900 69 28, ist nicht für Ihren neu bestellten Mercedes-AMG C 63 S Coupé vorgesehen. Das Ersatzteil ist für die Baureihe aus dem Jahr 2016/2017 freigegeben.
Ich empfehle Ihnen, sich dazu nochmals mit Ihrem betreuenden Verkäufer in Verbindung zu setzen und zu klären, welche Möglichkeiten für Ihren neuen AMG bestehen.
Gerne stehen wir Ihnen zukünftig wieder zur Verfügung.

Thanks for the info. I am fairly (but not 100%) sure that my 18 C43 without PE gets louder in S and S+ not merely because it runs in lower gears and higher RPM. Do you happen to know how?
1) C43 all variants have a Sound Generator Control Unit.
2) Only C43 Cabriolet and Coupe additionally have a Switchable Exhaust U78 Sound Generator and only if equipped with option B63 it has a Engine Noise Over Speaker Sound Generator Control Unit.
3) C43 Sedan and Estate do not have U78 and B63 specific Sound Generators.
Looking at WIS, I see different information:
- your car has "fake engine/exhaust-sounds" sent through your (front woofer and side-door midrange) speakers ONLY if your car has build/option code B63 (Sporty engine sound)
- there are 2 other types of sound generation that are referenced (I did a full search for "sound generation"):
+ for cars with build/option code 97B (Engine noise reduction via speakers): this is a noise-cancellation sound that's sent through speakers to REDUCE engine sounds in the interior (maybe SL and Maybach?)
+ for cars with build/option B53 (Acoustic ambient protection): this is an outside-the-vehicle sound generator that's enabled at low speeds to alert pedestrians of the car's presence (I assume it's for hybrid/electric vehicles)
If you want to know whether your vehicle generates "fake exhaust sounds" inside the vehicle, look up the build sheet for your car's VIN and see whether it has code B63 (ask Mr. Google to find Mercedes VIN lookup sites). Code B63 is listed as applying to "all" so it appears to be the only such code used for any Mercedes.
That is because across the pond, we view Estate wagons as a car for your grandma or a mom with a bunch of kids. (sorry, I was trying to explain to someone who posted something several posts back)
C43 AMG Sedan '19, Saab 9-3ss '03 Stage7, Saab 900 cabrio '92
mine it's a 2020 C43 and do not have the B63. It's a EU spec. Has the sport exhaust U78 code and additionally due EU regulations 6d, the 927 Exhaust Treatment, Euro 6 Technology and B10 Fuel Tank System For EU6D Standard, 968 COC Document For Euro6 Tech. Without Reg. Cert. Part 2
Confirmed by two separate owners in the C43/450/400 general WhatsApp chat that removing fuse 424 in the trunk panel makes an impact on cabin exhaust noise. Call it whatever you want, but the cars makes additional noise through the speakers to enhance the exhaust sound in the cabin with PE.
Edit: Also want to point out that this hasn't been confirmed with non-PE cars as far as I'm aware. I'm non-PE, so I'll test over lunch today and report back.
Little late to the party but decided to remove the 424 15A fuse on 2018 PFL PE Sedan. Will report back or not if something blows up.
For some reason, Americans as a whole have an aversion against Estate (Boots) or what we call here Station Wagons. Out of the very few car makers who offer one, VW just announced it will kill the sales of it here. Audi has the allroad but with only one engine option, the 2.0 turbo. All others with the exception of the Jaguar one are boring. The Volvo one is nice just not enough power. I don't get what the issue is so I was excited when I saw the Merc CLA 45S Estate but unsure if it will be available here.
I think the wagons are cool as ****! They kinda cruise under the radar so to speak. Nobody really notices them until you blow their doors off passing them. I had a 06' Audi A4 S Trim Wagon and loved it. Unfortunately it went with the ex wife. If I had a choice, the wagon would by my first pick.
Keep in mind those same dealers will insist that you have leather interior in your cars,when in actual fact its imitation,plastic,they tell you any old ****e,most sport exhausts are now, Active Sppeaker Exhaust technology

Guy down the street has an E63 AMG wagon. It's medium grey (maybe M-B's Selenite grey), the dullest, least attention-getting finish I can think of. The guy has a long, steep driveway, and when he goes up it, the car sounds like no wagon I ever heard before! It's the ultimate stealth street racer.
So after removing the 424 fuse, I can't make my car pop and crackle on demand. Maybe it's the weather. Will keep an eye for awhile longer before putting the fuse back.

Thank you. I will try this on the 2020 C43 sedan with the PE I picked up last Friday. I've been dying to get rid of the Rice-Krispies Snap-Crackle-and-Pop noises of a modern, fuel-injected car imitating the defects of a carbureted engine. I immediately turned the PE itself off and have tried "Slippery" Dynamic Select. Still, the car always sounds like a rear-engine car! (My first car was a 1961 Chevrolet Corvair, a rear-engine car, the original "Unsafe at Any Speed" model.)
(I needed a car immediately, and I wanted the power of a C43. I couldn't wait 6-8 months for an ordered car to be delivered. If I were lucky, that is -- in the third week of Nov., I read a complaint in another thread by a man who had ordered a car in mid-Jan. and still didn't have it. 10 months! So I had to take the PE, because that was on the car on the dealer lot.)
If pulling this fuse works, I am going to be overjoyed and outraged at the same time. I thought this sort of thing ended when we kids outgrew attaching playing cards to the front forks of our bicycles to make a Rrratta-Rrratta motorcycle sound!

is that with the windows down? The car definitely doesn't fake the pops and bangs - it just makes pipes in enhanced sound of the exhaust through the speakers
unless that fuse is controlling more than just the singular focus. Like additional fuel mapping, etc.

For past month, weather's been colder and with car catching covid and sitting in the garage more then usual, hardly needed to S+ my car. But I do remember 2 occasions when I wanted some pops and no pops. Just car revved high on S+ and no bangs between shifts, felt like S or C. Will probably leave 424 off for rest of the winter and see once in awhile on S+.
UPDATE : After few days the car farts and crackle on demand as usual. 424 fuse is still off, couldnt tell engine sounds from speakers before removing the fuse and couldn't tell it after. Will probably forgotten about this when summer arrives and maybe will notice something different when car is been on the road more.

Last week, I finally tried to pull one of the two fuses identified as "Sound" on the fuse diagram in my 2020 C43 sedan. They are not the same fuses as the fuses identified by RichardCranium3. I'm not going to give the numbers, in case other readers' diagrams are different.
I broke the top off the fuse, but the fusible wire seemed to be okay. i just pressed the fuse top back down and tried the car. I must have damaged the fuse, because the rear speakers have stopped working. That's okay with me, because classical music always comes from the front of the hall. Headbangers may want to get some replacement fuses before they experiment.
Now, the exhaust sound is now just loud, not super-loud. More important, it sounds natural, because it is all coming from outside the car. Also, the sound has a deeper tone, less treble sounds. The Snap-Crackle-and-Pop noises are unchanged (subject to the Dynamic Mode selected), but now they sound like they too are from outside the car. Most important, I will not feel embarrassed, if I give some people from my church a ride. So I can now live with the exhaust. But I am outraged that I had to do this.
I wanted to try removing the other fuse, too, This time I got a fuse puller. The clerk in the auto parts store looked up the type of fuse puller, so I assume it was the correct kind. Yesterday I tried it. Not having been born knowing how to use a fuse puller, I cannot see how to get the fuse puller down around the fuse. So I didn't try anything with the second fuse.
Glad the "sound" fuse did something in 2020 model. Like no sound on rear speakers (probably a fuse for an amp channel) and stopped some fake engine noise.
Aa for 2018, the fuse in question did absolutely nothing lol. Will pop back in when summer comes.

Thank you
If thy fuse offend thee, pluck it out
