Question about 2001 Audi A6
This issue is due to a faulty roof switch or loose/broken wiring connections. There are 4 wires in the roof window switch hooked up to 2 smaller harnesses that have 2 wires each. Remove the switch and use only the metal contacts in the harnesses. Use a light tester to confirm which one is the ground and live. this is how it turned out for my car.
One harness has a light blue wire with a black stripe, and a black wire. the blue one is live, the black one is ground. The other harness has a red wire and a darker blue wire (silly ford) these are the motor connect and return wires.
You must hook up the power (Live, light blue) wire to a motor wire. You must then run another wire from the other motor wire. To complete this circuit there is only one place that this last wire can go and it is to the ground. Once this is connected the roof should work fine.
To check the motors, reverse the operation of the roof by simply reversing the position of the live and ground wires in respect to which motor wires are hooked to (example, if the live wire was connected to blue motor wire and the ground wire was connected to red motor wire and it opened it, that would mean you would want to put the live wire to the red motor wire and the ground wire to the blue motor wire).
When doing these wire connections, it is advised that you have the ignition turned off. Once you make all the connections properly, you can turn on the ignition and if done correctly, the roof window will move. Once it is closed, remove the wires frome the harnesses and install a new switch.
Please do accept this solution and revert for further assistance.
