Engine Sound Via speakers
recently i updated my sound system myself and added a Sub/amp/tweeters/speakers. Its a plug and play kit by Gladen Mosconi and the results are fantastic and most probably even better than Burmester.
my only problem is that the new system probably also amplified the engine sound that is pushed through the speakers, which is impossible to turn off. You can just increase the intensity from comfort to sport or sport+.
Anyone has any idea how to stop this annoying sound, maybe pull a certain fuse or remove a cable ? Appreciate your help as i am about to remove the sound system.
after installing the amplifier, this artificial sound is amplified to a degree that it is so high whatever the setting you are choosing, whether its eco,comfort, sport or sport+. I hear deep fake engine noise through the speakers. Thats why i want to completely switch it off as MBUX doesn't simply give you the option OFF for engine 'fake' sounds through the speakers.
Stupid thing is, that according to manuals i newer cars there should be an option in the menu to just disable it. In my car (2021) it's not there. I'm pretty sure there were no hardware changes, it's it's just a matter of software updates or coding, but my dealer says they cannot do anything.
Again stupid thing - i know it can be disabled by coding, just not in authotised service. This is just plain stupid...
There was one post on some german forum, that was showing some amplifier/control module under the carpet in the trunk, between the battery and rear seat. It was said, that on cable should be disconnected to stop this sound. However my car doesn't have this module. Might have something to do with a fact, that i have "advanced sound system", which has own amplifier for front bass speakers.
Haven't found anything else on this really for W206.
I'm afraid 3rd party coding is our only option here

its written like that in the VIN Decoder : Engine Sound via speakers.
i contacted a couple of remote coders and i will update the thread later.

Open settings, press the "Assistance" heading 8-10 times.
The dealer menu should open:
Press Audio volume > ComfortVolumeMax:
Lower the AMGRACEAPP to your desired level:

In MY2024 there's an option to disable engine sound in MBUX. I assume hardware is the same, so it's only about software upgrades, however my dealership says they can do nothing about it. So much for customer care...

Now, i don't know - maybe all/some of them do not know how to code out B63, which we are looking for, but they definitely can do coding on W206.

I mean i knew they are restricting many things, but revoking certificates and making it virtually impossible to change anything is a step too far for me...
As much as i like my car, it might be my last MB because of that. Ok, if they would be willing to help me, it's a different story, i could even pay the dealership. But having no option whatsoever to fix what they messed up? And for example with this option they know they messed up, as with new cars there already is an option to disable it. So please let me have it added in the dealership or by coding. If both options are not available...
Maybe BMW next time? At least some coding is possible with i.e. OBD11. Used ODB11 for many VAG cars and it was great.
Anyway, i remembered something now. Stumbled across it when looking for info on audio upgrade. Will maybe try it today if i have some time after work.

Posts by Delorean2021. Seemingly unplugging one plug in the amp should stop the sound. Need to check if it works, as there might be different combinations.
Now, i have Advanced Audio System, so it does have SOME amplifier.
I found amplifier with part number a0009019819m which is branded by AMG. I assume it might be amplifier for Advanced Sound System with engine sound amplifier. Plugs seem the same as in Delorean's pic.
According to the post i'm referring to, unplugging blue rectangular plug from this amp stops the engine sound. Might be it's connection to ECU or any place, from where it takes info on the engine revs etc., which is needed to generate the sound.
I've seen pics where this amp was located in the right side of the trunk, under the carpet, next to junction box for battery mains. However in my car it's not there.
Will look for it now next to left wheel well, where ususally Burmester amp is located.
Will update you once i know something.

Please update the thread if you reach any solution. In my case i have the basic sound system which has no amplifier, so the audio is pushed straight from MBUX to the amplifier i installed. I contacted Gladen Mosconi and they replied that in our vehicles the fake sound cannot be disabled physically, only by coding and this makes sense, because in older cars they designed harnesses for their systems that disable this sound without any coding.
For example i have Digital Lights, but no projection functions (except for "spotlight"). I am willing to pay them subscription for this, but... in my car subscription adds only one animation, nothing more, and it costs the same as if it was adding all functions. I'm asking Mercedes if it's possible to get everything. Probably it needs coding or software upgrade, that could easily be done by dealership. Their answer - it cannot be done. Ok, if it cannot be done, i will not pay them for subscription, simple as that. Will not buy a new car because of that, but next time i will definitely think twice before buying MB. That's all they achieved with this.
Similar thing with this engine sound. I don't want that, it was part of the package, part i didn't care for. In new cars it can be disabled, in my it cannot. Again, according to them nothing can be done.
This is not something i call good customer service, and this is definitely not how you build loyal custmer base.
And funny part is, that many modifications made by customers were supposed to bring back things MB removed from the cars due to "chip shortage", like Distronic or Burmester. And that cannot be done now...

Wonder how it's done in cars without Advanced Sound system. I doubt it's done directly in MBUX unit.
Found somthing like this:
https://www.ebay.co.uk/itm/276483273803
Called "control unit for sound generator". Maybe that's what you have in your car?
Edit: Checked, and unfortunately it's a no-go. Found amplifier behind the left side trunk cover, next to wheel well, but it's a different kind of amp, not AMG one. There's also Ramses comms module installed to the same bracket.
Wondering now about this "control unit for sound generator". Looking at it's pics i even found a name "ECU Amplifier" on it. So this could be it. But i have no idea where it's located and whether is could be just disconnected, without impacting sound system.

Will do, but need to locate this amp first
