I always liked your avatar picture, wondering if it shows you just having lost grip upon trying to pull the train. But now I think it was the last moment before it ran over you and maybe the last moment before you became an internet troll. 😜 Btw, why don't you sue Ford for selling a car to...

That is exactly what I already posted and described, also refering to others having had the same experience. But maybe our commander "I know what other people hear better than they do" Zig will buy it now? Probably not ... You know that we are talking about frequencies in the hearing range...

The EB vido shows that the sounds are played through the speaker without the engine running -> proof they are fully artificial. Their frequency is linked to RPM, maybe in steps as the video shows, or continuously. Highly likely that its volume depends also on the engine load (torque) and/or what...

Those observations were before audio modifications. Nothing to do with it. Are you guys still fighting the existence of the ESE? That turning it via Forscan off made all described effects disappear doesn't convince you? With that in mind, all these new thoughts and speculations are not necessary...

To describe the audible difference I experienced: At low RPM/Idle a low frequency drone/rumble/subwoofer deep bass tone was gone after deactivation, and when strongly stepping on the gas with active ESE, all hell broke loose but especially from the sides it became louder like in a cinema when...

Allthough already posted in this thread: 1) The added sounds from the electronic sound enhancement interfere with the car stereo. If you are into car hifi and have upgraded the system, it distorts music/impairs in particular the subwoofer 2) It is not real engine or exhaust sound picked up by...

Quiet mode physically closes two of the 4 muffler (paths) directing the complete flow through the more dampening mufflers. So whatever ESE does inside (I cannot check anymore), outside it is way more quiet. Strange enough: at low RPM/idle it sounds more V8 than in other modes. I can tell as I...

727-01-01 is the line to look at, as shown in my screenshot. I corrected my typo. The first value in the third column needs to be set to zero, then ESE is turned off.

The clueless "Ford technician" speaks about ANC and speakers in the headliners playing engine sounds, that is exactly that kind of stupid confusion inducing crap that leads to threads like these getting long and longer. Your second video and the one I linked earlier draw a better "sound"...

Can you please first go to the motorcraft website and check your data so we know how your car is set up? Thanks.

@Junkyard Dog Go to that motorcraft website, enter your VIN and once you see the very long table on the website, search for the line 727-01-01 and post the complete line here. You do not need to download the file.

Physically it should as the sub only needs to play the music signal. It will sound like when the engine is turned off. That was where the difference was audible the most - engine off was great with the new sub, and once engine was turned on, most of the punch was gone.

Are you slow or something? IT IS PROVEN THAT SOUNDS ARE ADDED VIA THE SOUND SYSTEM! SOUNDS THAT ARE ARTIFICIAL LIKE IN THE VIDEO! Not real sound picked up by mics from the engine or the exhaust and played live through the speakers. Edit: Sorry for the wording.

a) It's not a "claim", it is proven. I explained it b) Ford themselves "claim" it, in fact, they even think it is a selling argument so they put it in their official press release: I posted the link a couple of posts earlier, so maybe you missed it (or didn't read the whole text - I should...

With stereo off and engine on I got a 46 Hz buzz which didn't change when I revved slowly, so that was artificial. The other speakers and frequency ranges I didn't check nor cared because the sub being messed up was what could be heard also with my ears. ESE was ON, then set it off, problems...

Means exactly what? On mine as well as on many others it was on, I measured and heard it, deactivated it and it was gone.

You would have to unplug more than one speaker. What should an unplugged speaker play? Do you still believe it's not there? Fords own statement to using it, frequency measurements, multiple users whose subwoofers playing normal only after setting ESE to off in Forscan should be proof enough...

ANC = Active Noise Cancelation to eliminate noise ESE = Electronic Sound Enhancement to add whatever sound elements to engine/exhaust sound Both played through the B&O speakers in GTs.

Noise canceling plays sound picked up by dedicated mics with inverted phase so that soundwaves eliminate themselves. This is done to eliminate unwanted noise. What ESE does is playing specific drone sounds depending on the engine revs and gas pedal as you can hear in the video. The confusion...

Don't mess around with lubricant, that's not the solution. Here it is explained what the problem is and how easy it can be fixed. For a dealer/workshop a 15 Minute job:
