Issue: Bose Fade / Balance not working correctly after MMI firmware update

[harvi007]

Hi Guys & Girls,

I've been doing some looking round on the web to upgrade my MMI. I have an MY2012 A6 Quattro with the 3GP MMI.

I have never had it updated and when I looked into how much it would cost and IF the dealer would do this for me, it was
becoming apparent that it would cost upwards of 500 GBP and you would have to convince the dealer to perform the update
for whatever reason/issue you had with the current one.

I then stepped up my searching and found a few guides outlining various parts to the DIY upgrade process.

To cut a long story short, I started on v517 so I had to follow the upgrade path of:

1) 8R0 906 961 BM - v518
2) 8R0 906 961 BT - v612
3) 8R0 906 961 CD - v614
4) 8R0 906 961 DG - v770

I'm currently on v770 and have performed some tweaks in VCDS.

The issue I had, was when I upgraded to v518, there was an update that applied to the Bose DSP which messed up the fader
/ balance settings.

I thought that going through the other upgrade versions may resolve the issue, but it did not. I do not believe that the
Bose amp (DSP) is in component protection mode as my sound does not cut out intermittently.

I did some searching on the web in regards to this issue, and found another person with the same issue, but he was from
the USA and his car was under warranty so the dealer applied TSB 2030465/7 update to resolved his issue. The worksheet states that the dealer upgraded the zug version from 715 to 814 and then performed an SVM update.

I'm unsure what the SVM update could be?

Link to the TSB article: http://www.revbase.com/BBBMotor/TSb/...dPdf?id=190128

Another search advised that the issue can be resolved using 'vcan-tool' not vag-com? But I do not have a 'vcan-tool' only vag-com VCDS.

I hooked up the car to VCDS and got the following fault code:

Address 47: Sound System Labels: None
Control Module Part Number: 4G0 035 223 C HW: 4G0 035 223 A
Component and/or Version: BOSE-G3-C7 H07 0160
Software Coding: 010000
Work Shop Code: WSC 02391 785 00200
VCID: 1D36415B04A269C9659-8048

1 Faults Found:

03389 - Data Set Implausible
000 - -
Freeze Frame:
Fault Status: 01100000
Fault Priority: 2
Fault Frequency: 1
Reset counter: 82
Time Indication: 0

Does anyone here know how I can resolve this issue with vag-com (if possible) or know of any other methods other than a costly trip to the local Audi dealer?

The only other thing I can think of is get the 8R0906961DR v814 update and apply this, but I'd still need to performed an SVM update according to the TSB article which I don't have a clue on how or what to do

Thank you for taking the time to read this and may thanks in advance for any suggestions or fixes.

Feel your pain, (did updates on C6 A6 and that was enought stress, paid a franchise garage £26 for the v5xx to 770 update and 1 hr labour for my C7 A7).
I can't help but .....

SVM = Software version management.
Basically it's saying the value in the bose adaptation unit is incorrect... it needs to be read out (decoded) and replaced with the correct value.

This is why I stopped doing my own updates to firmware and now only play in the VCDS...

Sorry once again, very well written Opening post...

Thank you for the reply, just a few questions then..

What did you say to the garage in order to get the issue fixed?

also when you had the garage perform the upgrade, was the car still under warranty?

Thanks in advance

sorry I may of not made my post clear...
I did not have your issue with the SVM code being incorrect.

I had version 518 MMI and car was out of warranty and they did all the updates.
I did approach AUDI dealer but they were more than expensive and unhelpful.

I knew there was alot of updates to goto 770 (which I needed for the car to run on it's own SIM for DATA & my mobile phone to connect via bluetooth).
I'd read up about the updates to MMI firmware and an issue with BOSE equipped cars and decided to got my local Audi registered garage (not a dealership).

Asked them if they could update my MMI to the latest (which was 770 at the time, my car is MY2012) and they said £26 for software & 1 hour labour (£60).
I said sounds good, I had them do the update when they received the files from AUDI. (I used German Auto Care Ltd in Leeds germanautocare.co.uk ).


I'd suggest goto to a specialist garage and telling then the story and they will most likely quote you to do a reset/ rewrite of the CODE for the Bose adaptation, if they know what they are doing. If they have no idea... just find somewhere else.

Problem is, I don't think you can make the correction to the version number without access to Audi data.

You will have triggered component protection, which requires a trip to the Audi dealer to be sorted.

I have exactly the same problem on my 2011 Q7 with 3G high. updated firmware and maps (via ebay) now balance/fade don't work and the sat nav instruction and handsfree audio only comes through the passenger footwell speaker.

I don't have a solution I'm afraid but very interested if anyone else does - short of going to a d£££aler.

Problem solved. After MMI update there has to be new parametrisation done to the amplifier. Vag Can Pro can do that on matter of seconds. Funny part is I have VCp but until now I disnt know it can do that. There is no need for the fw downgrade or so, if you update your mmi and 03389 problem occured, find some eith VCP and youre good to go.
