Active sound module unplugged vs Programming ASD off

I must have mucked up something. I have no faults or errors; in fact I even routinely run transmitter to clear potential fault lights after each coding session.

A month back I coded FEM body to separate ambient lighting from gauge cluster dimmer switch (ambient_nachfuehrung). Even after that I have never noticed my ambient/interior light pulse. I reckon that might have something to do with that. I'm going to code that back to factory and report back.

[Mr. Hankey]

I've done the same coding off and on several times and have not noticed this at all.

So what the consensus on coding ASD_SOUND_OFF? I gather that it doesn't completely turn off ASD compared to changing the Model Range F20 in the ASD module, but how much quieter is it compared to stock?

I actually like ASD, but wouldn't mind if it was a bit less amplified to allow me to hear more of the true exhaust sound coming from the outside.

[Mr. Hankey]

My estimate is that it's about or just about above half. It's almost like there are 2 places the active sound gets amplified - between the ASD module and the main amp as well as in the head unit. If you turn off in the head unit it still seems to be sending signal to the amp. Perhaps one is the "brain" that ties into RPM range, while the other is baseline noise...but I'm not that smart. All I know is the sound is still there and a little quieter. Just coming from the wrong place (IMO) from a "soundstage" perspective.

Help pls guys!

In the F87 M2 - so doing no.3 and coding ASD Module : 3000 "Model Range" to F20/21.

Yet, when i log back in, the ASD Module : 3000 "Model Range" is being set back to F87.

Any ideas what is resetting this?

Thanks

That code I listed above in HU_NBT is the only one I've seen. So coded ASD to F020/F021 this morning and it is now the same as unplugging the ASD module completely.

So here's a summary of what I've tried on active sound:
1. Unplug ASD module in the trunk = Turns off ASD completely
http://f80.bimmerpost.com/forums/sho....php?t=1082175

2. Leave ASD module plugged in and code HU_NBT "ASD_SOUND_OFF" to aktiv (default nicht_activ) - Quiets down the ASD but it does not completely go away - seems to be the advertised 3-5% of cabin sound BMW claims (not 25-40% which is what my ears hear in sport+ with ASD on), definitely quieter than stock but definitely still present rounding out the sound.

3. Leave ASD module plugged in and code ASD Module : 3000 "Model Range" and set to F020/F021 = ASD completely off, without having to pull the trunk apart and unplug the module directly.



The take home then is if you don't like how intrusive the ASD sound can be in the cabin, but don't want to turn it off completely, then do #2 above and it will quiet it down quite a bit.

After 1200 miles, I really like it off.

Are you sure you saved the changes before you FDL coded? one way to know is when you read ECU after connecting to car, check the value. If it somehow magically resets, try setting it to any other value F01, the value doesn't matter as long it's different than you car model.

Yeah pretty sure I saved it, as coded other things in the same session, But will have another go tomorrow

Must have been an error between seat and ODBC port as yes - it worked today!

Much improved.

I turned off both 2) NBT and 3) ASD just to make sure

Hi

I previously disconnect my ASD, but recently plugged it back in to carry out the full I-Step update. Unfortunately, the ASD ECU won't update any longer.

Any ideas? It's the last ECU to do. I assume it's due to being previously unplugged?

Thanks.

What's the error from Esys, assuming you are using it? Try clearing the existing faults using either Esys or Rheingold then flash again.

[M4GTS]

Doesn't actually show an error code to clear.

So you checked with Esys or Rheingold and there was no faults at all? And what was the Esys error during flashing?

[M4GTS]

Let me pull the screenshot and get back to you. My issues seem to wider than just the ASD coding. Angel eyes and key fob window functionality are gone following Update also.

If you or someone has flashed your car, aka updated the I-step, then you would loose most coding.

[M4GTS]

It's the factory defaults I seem to have lost though. There was no aftermarket coding on the car. Sidelights/DRLs and remote window control is all that's impacted as far as I can see.

Hopefully we'll rectify tomorrow.

Thanks. Going to try #3. If I left #2 alone, I assume it won't cancel/interfere with each other? It's easy enough to change #2 back, but was just curious what would happen, haha.

i coded mine out and would do it again.

does anyone know if second parameter is necessary?

3000à Model Range ​​​​​set to: F021
​3000à Engine Type​​​​​​ set to: N20B20

i did it both ways and can't tell difference between just doing F021 by itself and F021 and also setting engine to N20B20.

​

[fandroid]

I am new to coding and have hard time to find ASD 3000 'Model Range'. When I looked at the ASD modules, I think 'Model Range' is 'Baureihe'?

See the attachment.

Can some one confirm? Thanks!

[milthorst]

You are correct. Baureihe = Model Range

1. Programming: HU_NBT "ASD_SOUND_OFF" to aktiv (default nicht_activ) and the active sound is quieter but still present in my car to some extent.

2. Unplugged ASD Module in the trunk and for sure there is no active sound at all. Car is very quiet even in sport plus but can reasonably hear exhaust and feel revs

Today I plugged my ASD Module back in, and have ASD programmed off in HU_NBT and there is DEFINITELY some active sound happening now....even though it is "programmed off." It's still quieter than when ASD_SOUND_OFF is set to nicht_aktiv though.

It seems that some processing is still happening and some fake sounds getting passed to the HK amp with it programmed off.

Is there another module I need to code or FDL I'm missing to completely turn off ASD without leaving the module unplugged?

Anyone know how to turn off in BMW M3 Comp 2021, already tried by bimmercide, unsuccessful.
In nbt, there is no" asd sound off"
Please 🙏 help.

Regards

Likely different version of the software than from when I programmed this. Best way then is to unplug the active sound module in the trunk.
