My audi a6 c7 2011 front camera recently stopped working. The code I had got suggested there was a short circuit to b+.
To diagnose the wiring I cut the cable and tried to connect it to a 12v power supply but I need helping figuring out which ones are the positive and negative cables and which ones for video.
