F10 Code: Turn off ASD (Active Sound)

Hi all,

I'm new to this community and hope I'm not making any mistakes with this very first posting...
So here's my contribution: As the lucky owner of a new M5 F10 I needed a way to disable the 'Active Sound' module because it really disturbed me. Pulling the fuse was not an option as this disabled the complete sound system and removing the ASD box in the trunk would be to invasive.

That's what I did using E-Sys:
There's a special ASD module that has several preconditions before becoming active (see the 'Aktivbedingung' folder in the screenshot): Only certain models will activate the ASD. Those models are listed as functions, e.g. 'F010 true()'. So I looked a little bit lower in the tree and changed

3000 ASD-Configuration - Funktionen - Baureihe to F021

As you can see on the screenshot, the F21 model won't activate the ASD.

I made several tests and compared to pulling the fuse so I'm 100% sure this little modification really disabled the ASD in my car :-)

BTW, for those willing to change the sound: There's also an option 'Motor' where you can change the installed engine (for Diesel sound try N57D30). I haven't tested all these parameters - I'm glad that nasty module is switched off

Best regards

I don't have an M5, but nice find.

Send me you ASD modul in the trunk to see if we can retro fit it on other models. If it works I'll buy it from you

Great find!

I understand them putting it on the diesel, but I find it odd that they put it on the m5 as well. You would think the M cars would be loud enough.

Just coded this and it worked without issues. Thanks!

@Travel4surf: Thanks to the information in this forum I don't have to rip the module out of the car because I can code it away ...and you do not want to hear the sound this module generates, believe me!

@jdco: Glad to read that it's working in other cars, too! It seems I'm not alone complaining about the fake sound :-)

Yes, the M5 is really loud enough. And without the ASD I can enjoy it even more because now I know it's real!

Interesting.....I wonder if people that want it could just pick up the sound processor in the back of the car and have this coded to be on. 535 that sounds like a M5? lol

Alan

I love the sound of my M5.. It's definitely loud enough with my Gruppe intake and Akrapovic exhaust. ASD is lame imo

What is the name of your ASD CAFD file?

can you turn UP active sound???

can anyone tell me what is ASD? lol

Active Sound Design.

"Behind this marketing term is a fairly simple idea. The new M5 reproduces the car's engine sound via the in-car audio system. In other word, if you're sitting inside the car you not only hear the engine coming from outside, but also an audio track of the engine based on throttle input, speed, and engine revs. As BMW puts it, this makes for better feedback as you hear exactly what the engine is doing. Another obvious benefit is that it allows to change the noise levels based on your driving behaviour as the reproduction by the audio system gets louder and more intense in Sport and Sport+ settings."

btw, Can I enable ASD on F20? and How?

No. You need the ASD Hardware including the ECU.

all right, forget it~ hah

Not sure if I got the right file: May it be CAFD_0000000F_005_024_233.ncd?

Hi,

possibly... but I haven't tried it.
there's a key for the built-in audio system with several option ('TopHifi' in my case, others are 'Stereo', 'Hifi', 'Branded Hifi' and 'High End'). I'd assume that this adapts some frequencies so that the speakers are able to play the sound without distortion.

And then there's a key called 'Leistungsklasse'. I'm not sure what may be the proper english word for it: Something like 'performance class' or 'power class'. I have no clue what this key is triggering.
The options that one can set here don't help any further: 'ML', 'UL', 'KL' and 'OL'.
Perhaps 'M' stands for 'medium' and 'U' for lower (in german: 'Untere Leistungsklasse') so 'O' may be 'Obere Leistungsklasse' (upper class). If this guesswork is right, then OL may be louder than ML.

If there's a great demand for it, I could try out all those options...

As far as I know, at least the M135i is equipped with such a module.
Here you may buy a spare part for about 230 USD:

Perhaps it fits in other models, too...

Edit:
Here are the part numbers for the M5: http://www.leebmann24.de - M5
Looks like the newer models share the same part #65129289971 with the M135i.

Yup. I have the 5 door M135i (F20) and it has an ASD module - physically verified in case anybody doubts

First - thank you very much for the find. The ASD in my M135 is not bothering me yet but it is nice to know where to look in case I want to silence it. Agreed that pulling fuses is no way to go (and on at least some cars the sound is looped via the ASD unit so unplugging it also kills the head unit sound).

But is is strange that selecting F21 body turns your ASD off - you also get a F21 (3 door 1 series) variant of the M135i and it has active sound. Perhaps the ASD recognised that is is mounted in the "wrong" type of car and then just shuts up?

LOL for a diesel M5!

Maybe my car has a somewhat older firmware installed, compiled before the availability of ASD in an F21 (although my M5's built date is end of 2012...).
Perhaps in newer firmware versions there exists a new function 'F021 true()' and my workaround doesn't work anymore then. Currently the F21 model is the only selectable one that has no 'true' function in my configuration.

- I keep my fingers crossed that there will be another way of of deactivating the ASD if my car happens to get new firmware with an inspection!

I would be interested. I'd like to make the active sound louder on the M5.

Hi

What MOTOR option is programmed on a real M5? Would love to try it on my M550d...

Thanks

Jut came back from experimenting...
When trying 'UL' the sound was a little bit more quiet but there was some more 'hammering' in the sound.
Trying out 'OL' made the sound deeper and more powerful. I'm not sure if it really was louder, too. But I think OL would be an option you should try out!

Hi,

Motor=S63B44, Leistungsklasse=ML.
I'm curious if this works - and if the ASD is strong enough to overlay the diesel sound!
