Recoding Radio's for features and Bose Configuration

NOTE: all the information presented is personal opinion and presented in good faith, nothing on these pages is validated or endorsed by Audi and you should be aware that you could make changes that may disable features of your car.
Always note down the original setting of anything you do and if you are not confident with what you are doing then just don't do it.
YOU HAVE BEEN WARNED.

The following text will describe how to code radios for optional features
the ignition doesn't need to be on for this but the radio should be switched on.

The steps are useful for installing new radios or for testing Bose on/off  and also for ensuring the phone mute behaviour is correct for your installation.

Concert/Chorus 1 models
(up to year 2001 spec, single control in the center)


In VAGCOM select "56" RADIO



then Select "07" RECODE.

Example Code 00517
 

Digit Description
1 Country ID (0 = standard)
2 Sound Coordination (0 = standard)
3 Number of passive speakers
0 = No passive speakers (Bose)
1 = Front left (Bose with hands-free phone)
2 = Fronts passive, rears active
5 = Fronts passive, rears non-active
4 Sound System
0 = standard
1 = Bose
5 Radio Configuration
1 = No CD changer
3 = With CD changer
5 = With secondary display
7 = With CD changer and secondary display



00217    - Would give you Bose equalisation and Fader control. (Useful if you wanted to use the radio Rear output to power an additional subwoofer.)

00205    - Would be a standard equalisation with Fader and no CD Changer.

00517    - Should be a default Bose setting
00207    - Should be the default for Standard setting.

 

Concert/Chorus 2 models
(2002+ spec, 2 controls at the edges)




In VAGCOM select "56" RADIO

then Select "07" RECODE.

Example Code 04632

Digits
1 - Country ID always 0

2 - Radio configuration Always 4 for TT
    (0-A8,1-A4,2-A6,3-A4Cab,4-TT,5-A2)

3 - (FO-Fader Off, BO-BOSE Config,
     AO-Active Amp off for telephone call)
     0=

     5=FO,AO
     6=BO,AO
     7=FO,BO,AO

     2=TEL
     3=NAV,TEL

                    Thankyou Albert for this info.)

     3=DIV,CDC
     4=MFS

04732    - Would give you TT setting, Bose equalisation, Active amp off via phone and NO Fader control, Navigation and Telephone inputs active and a CD Changer installed

04632    - Would give you the above but With Fader control (Useful if you wanted to use the radio Rear output to power an additional subwoofer.)

04532    - Would give you TT setting, (NO Bose) Standard equalisation, Active amp off via phone and NO Fader control, Navigation and Telephone inputs active and a CD Changer installed

04232    - Would give you the above but With BOSE and the active Amplifier would remain on if the phone mute were triggered Fader ON. (Default I have set mine to)

I have no idea what SBS is.
DIV - Diversity box is a Television antenna system.
MFS - Multifunction Steering wheel, self explainatory.

04332    - Should be a default Bose setting
04032    - Should be the default for Standard setting.

Adding LW Frequencies
(adds to the AM band range):-

Select Radio controller '56'
Select Adaptation '10'
Select Channel '88'

The OEM STORED VALUE will be '1'
Enter a '0' in the NEW VALUE BOX
Select TEST
Select SAVE

Done and Go Back, then enjoy! 
(Only tested on a Chorus 2 so far)

Just an additional Check for CD wiring:-

CHECKING THE WIRING CONNECTION FOR THE CD:-
Assuming you know the CD Changer is there!

Switch the radio off

Press and Hold the MODE button and switch the Radio on.

CONNECT and CD should appear on the display

if NO CDC appears then there is a problem.
