Active Sound Design

Hi all

Newbie here and M340iX owner. Came from an M135iX and what a massively better car!

I am wondering if ASD is in my car? It’s extremely plush and quiet, and the option on iDrive to change engine sound is absent, so I am thinking not.

I absolutely hated it in previous BMWs so I want to turn it off if I have it! Don’t think I do though.

I think it does, but I haven't really played with it (yet):

Well that's all my knowledge gone

To my knowledge, it's only the full fat Ms with that ability. You can code the active sound on or off, with the likes of BC, though.

Not sure if it's just certain models or if it's different versions of firmware. When test driving before placing an order I borrowed a 340d and a 340i, the d had the sound options in the menu, and they made a significant change, the 340i didn't have it

Had it in my Golf R, though had to code it way down from its default setting to about 15%. Just to give a bit of bass to the 4 pot engine note. The default was so intrusive that it gave me head aches after a while, and got tiresome after a few days of owning the car. Don't miss it at all in the 40i even though sound deadening is pretty good, but then I've moved on from the hot hatch dalliances (though I know we are all different). If it was available, the one time I could see myself using it would be in Sport manual to be able to hear the engine a bit more easily for gear changes. If sunroof/window open, then sometimes a little hard to hear engine note.

Think it does but you would need to code it to make changes. It's not as obvious as it was in my old f31 340i however.
Just do the exhaust flap mod that helps a bit but the g series cabin is just quieter as are the exhausts due to noise regs sadly.

From what i've seen this feature of changing the active sound isn't something you can change on UK cars.

Saw one of Joe A's recent youtube videos and a new German M4 has a button to change the active sound on the fly but his British M3 doesn't have any ability to change it, even in the menus'. I assume on the German M340i's you can change it but we don't get it in the UK, which is why its in the manual.

It is on my M440D. Swiss spec.

Option to choose between sporty, drive mode-dependent, balanced or reduced.

I have mine on reduced. Not sure if that means less than normal added sound, or actually noise cancelling reduced (which would be great). Either way, I don't hear any digital white noise.

On a diesel it just adds rev-linked, gruff, digital "GrRrRrR" white noise when accelerating. And as I mostly torque surf with low revs it is both pointless and annoying to me. YMMV.

I don't get why they remove seemingly random items from RHD UK spec cars.

I saw on the latest Audi RS3 german spec cars can get all sort of colour design packs for the interior to make it look better, but in the UK all we get is plain old boring black interior.

The option marked "Reduced" does the trick for me. I don't hear any artificial sound then. Not sure if "reduce" just vastly minimises the added sound, or actually reduces any sound as in sound cancelling. Strange choice of words using "reduced" and not "off". I'll post a photo later.

The other options overlay a gruff, digital "GrRrRrR" noise on accelerating.

I have that on my 330e. But I think some of the M cars have more control than that. I think that's what people are talking about here, unless I've got the wrong end of the stick.

The dealership would see that come servicing time and could potentially cancel the warranty though, no?

Welcome!

While we don't have the facility to adjust the engine register (as in the G80) through the iDrive, in Sport the engine tonality should definitely drop and become more sonorous (from within the cabin), something reciprocated by a more raucous exhaust note. As folks here suggest, you can certainly do a quick intervention with the exhaust flap to keep it permanently open. But in my experience with the 40i, it all comes to how warm the exhaust itself is: on a warm (re)start, after a brief pitstop for instance, it'll bark into life with cascading burbles. Spend half an hour in the car and the exhaust really comes alive.

Inside, meanwhile, I've been gratified by the fact that the sound never seems that artificial or remodulated. People have complained about the piped in orchestration of the engine in the new M3 (though, to be sure, it's still 'real', just refracted from the engine chamber), but I don't get the sense that we have that level of intrusive mediation in the 40i.

I had an ‘18 M240i coupé and the active sound on that was absolutely horrific. It would suddenly come in super loud even in comfort, that was actually the reason I got BimmerCode, so that I could turn it off. Once I did, the car was super hushed. BMW must have made it much more sophisticated if the M340i has it at all, as I can’t tell.

Just to follow up.

These are the options I get for ASD.

For me, "reduced" is lovely, quiet and refined, any other mode is just an overlay of annoying throttle-sensitive, digital white noise "GrRrRrR". YMMV.

Thought I was having a senior moment but no, I definitely don't have this option.

If it's missing it might be the istep you are on.

Have you even had a software upgrade ?
