No, the RNS-E relies on can-bus to activate it and tell it your lights are on.
What year is your A6, after 2001/02 your car should have can bus for the instrument cluster. You can get the can bus signals (HI & LO) from there. Have aread around the forums for more info.
This will improve your installtion so much is you have can bus in your car and install the wires to your RNS-E. If you do not have can bus, you can buy can bus converters which will generate lights/ignition etc onto the can bus for you from the normal analogue signals in your car
