Enabling *** & subwoofer control without VCP - FL success

Thanks, THIS is cool, just did it on my FL A3 Sportback, MIB2 Harman MHI2 with Audi Sound System.

I first edited the 00x003B00 with subwoofer dial range set to min= F7 , center= 00, max= 09.
Calculeted the checksum and a restart of the radio, and there the sub dial was in the sound menu, great, but the dial did nothing to my listening, just like some other here reported, i think this just enables the dial knob on the display, and the range the dial can do, the actual gain setting is set in the other dataset 00x003000 below here.

Then i edited the 00x003000 with subwoofer max gain changed from 00, now set to = 5A. (I think this could be either 5A or 64)
Calculeted the checksum and a restart of the radio, and now i can confirm the subwoofer dial works.

This will work if you have or are looking to install the Audi Sound System. I'm not sure if this would enable the menu on the B&O system.
 
I have a Audi sound system. I install this solution and I Think its works. I think so.. ;)

Could somebody help me? What I need to verify?

Thanks a lot !

Do you have the FL(F3) or preFL(8U)?

Do you have Carscanner or another tool to read Datasets?(ODIS/VCP/Carscanner)

I’m not sure, if it works, because I never worked with Q3 8U or this generation. But if you have 30-50$/€ over, buy a ELM327(e.g Carista) and download CarScanner App and try to read out 0x3000 dataset.

I think it should work, but I’m not giving any guarantee:)

Hi... I bougth the ELM and install the CarScanner... unfortunatelly I cound read the datasets, even the basic data cant be read :-(

I have sent an email to the CarScanner develop and he told me that the CarScanner only works with MQB plataform.. :-(

Do you know any other app that could help me to extract these datasets ?

Thanks, THIS is cool, just did it on my FL A3 Sportback, MIB2 Harman MHI2 with Audi Sound System.

I first edited the 00x003B00 with subwoofer dial range set to min= F7 , center= 00, max= 09.
Calculeted the checksum and a restart of the radio, and there the sub dial was in the sound menu, great, but the dial did nothing to my listening, just like some other here reported, i think this just enables the dial knob on the display, and the range the dial can do, the actual gain setting is set in the other dataset 00x003000 below here.

Then i edited the 00x003000 with subwoofer max gain changed from 00, now set to = 5A. (I think this could be either 5A or 64)
Calculeted the checksum and a restart of the radio, and now i can confirm the subwoofer dial works.

I have a PFL A3 8V that I retrofitted the FL MIB2 system in. I'm having trouble getting the sub control back. Could anyone help me out?

Just thought I’d share that I finally got around to applying these modifications to my B9 S4. Changes went without a hitch and things definitely sound a lot better with my upgraded speakers and amplifier.

I managed to track down someone who had made tweaks for their B9 A4 and applied their code directly to mine.

Feels like the sort of thing that would benefit from a car by car repository.

Happy to hear that. Based on your previous post, I understand that you have an early B9 model with the old MMI and B&O. This old MMI can't officially be updated to have the subwoofer control and the "hack" available will change the A4 Avant image in the MMI to a Q7.

I have a 2016 Audi B9 Avant with B&O and no subwoofer setting. So, what would specifically be needed to add the subwoofer setting without changing the image to the Q7? I would have someone do the coding for me, but it's a bit hard for me to understand all the details discussed in this thread, especially as most people are discussing the A.S.S not B&O. Can you share that? Thank you very much.

Hey everyone, just looking for a bit of help here.

I"ve just recently replaced the MIB2 on my 2017 Audi A4 without B&O, coded it and patched it, switched coding to internal amp however my sound is still off.

I stumbled across this page and it seems this would be my solution however I'm really unfamiliar with this process.

Would anybody be able to help me upload the correct dataset to my MIB using ODIS-E as its the only software that i own.

I would really appreciate it, thanks!
 
Hi @Oli250, Please can you help me to enable subwoofer knob and increase gain a little bit for my Audi Q7 4M with MIB2 high Harman unit. I have attached original dataset files here as txt files.

I tried it with Hex 010 editor but didn't get through it so your help will be much appreciated.


Thanks a ton.

Hi all

I thought I would share that I was able to enable the Audi Sound System and the subwoofer menu using just a bluetooth ELM327 dongle and the CarScanner mobile app. No VCP/ODIS/etc. required, though it did take quite a lot of research!

Looking through the forum I didn't see anyone having much joy with this so thought I would do a quick write up. This applies to the MIB2 MHS2 (may need correcting but I believe that is the 'Delphi' std model). Following any of the below at your own risk etc., especially considering you may not have the same MMI hardware I do.

I was able to figure all this out thanks to the write up by Alex over at MQB-blog.com (https://mqb-blog.com/en/2022/02/21/sound-dataset/). I won't go into much detail as it's all very well explained there. Briefly, Alex has worked out the breakdown of the relevant addresses from the 5f module that control the internal amp output in the MIB2 (addresses 0x003000 and 0x003B00). To get the subwoofer menu working I also had to update the MMI firmware to MU 2103.

5f address 0x003000 contains the configuration for the sound processing on the internal amp - I used this to enable the centre speaker and sub channels of the amp but there's certainly a lot that could be done here. This would be of particular interest to anyone undertaking more complex audio projects - channel specific EQ filters and the DSP settings can all be manually tweaked / disabled here.

5f address 0x003B00 contains the sound configuration. Here I was able to enable the controls for the subwoofer menu.

A brief "How-To"
1. Use the CarScanner app to read module 5f, addresses 0x003000 and 5f 0x003B00. These can be found in the coding section of the app under 'dataset dump'. I copied the values out to edit on a computer using a hex editor. I strongly recommend using 010 editor with the templates available from the MQB-blog post linked above, these identify the various bytes and values so you can easily make sense of the hex data.

2. To enable the Audi Sound System & Subwoofer menu I updated the following bytes:
0x003000
Update Signalflow to 30 (6ch center sub 9.1), this is the first byte in the address
View attachment 258864

0x003B00
Update Struct Knob Subwoofer range to -9, 0, 9
View attachment 258865


3. Once the relevant bytes have been updated using a hex editor the checksum for each address must also be updated to avoid any errors. The checksum is the final 2 bytes in each address and is calculated using the CRC-16/CCITT algorithm. To calculate the new checksum take your updated addresses and copy each one without the old checksum into the calculator at crccalc.com and set the input settings as shown below. In this case the checksum to be copied back in would be 0CBC

4. Take your newly updated 0x003000 and 0x003B00 address parameters (without any spaces, new lines, etc.) and use CarScanner to write these back on to their relevant locations on the 5f module. Restart your MMI and everything should now be working.



Any queries let me know, if there's interest I'm happy to expand on this or add some screenshots of the process.

This looks amazing work. I'm very new to all this and need the most basic instructions I think I've got most of this understood but how do I write it back to carscanner if I have the new address parameters on the laptop? I can sort of piece together all of the rest from all your helpful advice on here. It's probably not something someone like me should attempt being so clueless on this but I am struggling with the controls after coming from a superb with canton. Thanks in advance

Hi mate firstly great post. Thank you again. I managed to get my sub menu and centre speaker working. Where iv ran into an issue is that I have a 2014 pfl Audi s3 saloon with Audi sound system. I retrofitted the mhs2 mmi that was previously in a 4 channel car and after adding the sub menu has retain the eq and the rest of the settings for 4 channel car. Would you have the full 0x3000 that you found in an 8v with Audi sound system so I could swap over the relevant parts I need to get my sound system working as it should. Again thank you for the great work.
 
Also in addition to this iv created a web app that you can import your 0x3000 file to change any eq or speaker settings with sliders and a full eq graph. If any one wants it just hit me up. Allows you to then export the modified 0x3000 file with corrected checksum
 
If your MHS2 has an MU version above 140 you can install P2035 and flash the 9VD dataset. Install the dash speaker and subwoofer, upgrade the front door speakers. If your car already has 9VD speaker setup, then flash the dataset. The one public available is for MHI2 but also works on the final MHS2 software.

What you have at the moment is a mess and playing around won't make it better without the correct base.
 
Hi mate thanks for the reply. So my car came with the 9DV speaker setup on my old mib1 mmi so I already have the centre speaker and subwoofer. When I upgraded the mib1 to mhs2 the mhs2 had only the 4 channel speaker dataset on it. I am
Currently running latest p2035 software. If you have any idea where I could find the publicly available dataset for my car (s3 8v saloon with sub in parcel shelf) that would be great. I have edited the dataset to give me the sub menu ect but the eq and other setting are wrong for the sound within the car. So if I could find the correct dataset for my car that would be great I can just flash that.
 
Flash with ODIS Engineering on 5F. Or VCP if it takes xml. Keep in mind this is for left hand drive. If you're in the UK you must get another dataset, but this will at least be a lot better.
This dataset will enable the subwoofer menu, so no need to fiddle with it.

@viciouscycle360 Just seen this, glad you found the post useful. This is the stock 0x3000 dataset for a RHD A3 Saloon with 9VD if you want to compare - the time alignment for L/R channels is balanced so would be interesting to see if there's any differences from LHD to RHD.

I've been playing around with the EQ recently having swapped out the front speakers for 3-way components and adding a DSP/amp driving everything except the rears - I've kept the rears amped directly from the MMI for a bit of fill and used the channel-specific time alignement and PEQ in the MMI to tune alongside flattening the other channels being run into the new DSP (tune done with a calibrated mic and REW). Makes a big difference! It would have been interesting to see how much the tune could be improved on the stock system before I started upgrading components.

Your web app sounds very useful if you're willing to share?

Sound Settings Viewer Becomes Editor. Finally.

My passion project keeps evolving and getting muscles. The latest major update was published yesterday, which took me about a month to complete as opposed to the initially planned 1-2 weeks. The new version is now able to open sound datasets (any MIB generation) and interface configuration...
