USB/AUX Sockets retrofit in Pre-Facelift A3

Hello,

I’m retrofitting an MIB2 unit in a pre-facelift A3. As part of the retrofit I’m installing the USB/AUX socket from a facelift A3 (81A035736).

The new module has two connectors, one is the same as my current AMI unit but the second has a different connector. I can source the connector it’s self but I need the pin outs in order to connect to the green Quadlock connector. Does anyone have these?

If not then a couple of pictures from the black connector on the USB unit and from the rear of the Quadlock would be extremely useful as the wires are colour coded. These could be from any facelift A3?

The attached pictures show where the cable goes from and too.

Many thanks,

So I have now located the Pin Assignments for the Quadlock. I now need the Pin Assignments for the USB/AUX module. There are 6 pins in total. The part number is 81A 035 736 but I believe part number 8V0035708 and 4G0035736 is the same. Would anybody be able to look on Elsawin whether the Pin Assignments are available for either of these?

On the Pin Assignments for the Quadlock it refers to "R199" if this is useful for Elsawin?

Any help would be much appreciated and would also be of great interest to anyone doing a MIB2 retrofit who wishes to get Apple CarPlay/Android Auto working.

Many thanks,

 

Did you manage to fine a solution? Im at the same point

 

Hello,
here is the pin out of the 6 pole connector:
1- KL30 (Battery+) red-black striped
2- KL31 (Battery-) brown
3- USB_VBUS green-yellow striped (iPod detect originally in preFL cars MIB1, red)
4- AuxIn_R yellow
5- AuxIn_LR- gray (in preFL cars, brown)
6- AuxIn_L green
Do you know what is the part nr# of the 6 pole connector?

Hi,

New to the forum. I am also looking to install the USB interface, does anyone know the parts codes for the plugs to use the old loom if possible ?

 

Seuzo, did you track down the part code for the connector as I also need it.

 

Hi
You will need to change loom because the usb pinout are not installed.
regards

 

Cheers for confirming. I thought if I could get the plugs and the schematics, I could change the existing wiring to suit.

 

Got the loom. Anyone know what pins the red and black wires from the usb interface connect too ?

 

Yes, it is 8W0971636.

 

Hello

i also did the retrofit from to MIB2 in my 2015 Audi a3 8v
i only need to connect the usb harness
bought this cable from china

do i need to remove the old green connector from the quadlock mmi
and replace it for the new one from the red circle i made?


And where do i need to connect the 2 wires?

 

Hello,
yes, just replace green connector (block "C") with the new one. You had AMI interface I think this is why you have a green connector already.
The two wires you asking for is the 12V (Battery + and -). You can use the supply of MIB2 or central keypanel or cigar lighter ...

 

Thanks for the info, connected today and works fine
