I have installed a DIS dash into my 2002MY Audi A3 8L TDi PD130 and has been coded by a dealer so it starts the car on all 3 keys.
Previous dash part number was 8L0920950D > Which I changed to 8L0920980N (with the grey/white dials)
I have Earthed the pins for the Washer Fluid/Bulb check warnings to the dash just behind the headlight switch, this turned the warnings off!
Grey 32 Pin Plug on back of Dash Insert which I earthed:
Pin 14 - Brake Light
Pin 15 - Washer Fluid
Pin 16 - Reverse/Sidelights
Wiring for the Stalk:
Pin 17 - Stalk control Left (wire colour- Green) -Connects to the black 6 pin plug on the Stalk (Pin 2)
Pin 18 - Stalk control Right (wire colour- Blue) -Connects to the black 6 pin plug on the Stalk (Pin 1)
Pin 17 - Stalk control Reset (wire colour- Grey) -Connects to the black 6 pin plug on the Stalk (Pin 4)
The new dash works fine apart from the Radio does not turn on and off with the ignition neither will it illuminate with the sidelights/headlights but I can turn it on manually fine but with no button lighting. I believe this issue is to do with the CANBus wiring and the 20 pin Black Connector on the Concert 2 Radio.
Looking at the wiring diagram I need to connect from the Grey 32 pin plug:
Pin 5 > Pin 7 on the 20 pin plug on the radio (CAN high speed display (high +)
Pin 6 > Pin 12 on the 20 pin plug on the radio (CAN high speed display (low -)
My problem is that there are already wires in these 2 pin locations on the radio,
Do I need to cut both wires and isolate the ones which are already installed and replace them with the wiring from the Grey 32 pin plug from the dash straight into the 20 pin connector?
do I need to join into the factory wiring so my radio will come on with the ignition and light up with the sidelights?
Also I am trying to find the correct location to install the passenger door open warning, I have tried to use the Brown 10 pin Connecter in the passenger footwell/a pillar at Pin 7 but for some strange reason with the passenger door shut the warning stays on and keeps the interior light on when it should be off. Im finding that there is a feed coming through the Grey 32 pin connector from pin 8 which needs to be connected pin 7 on the brown connector which I believe is back feeding somehow?
Please someone help, I'm having a mare with this :/
