Below is a list of the wire colours rom my 2009 Exeo, which I used when fitting a double towbar electrics kit:
Edit: I've added a note next to each one, where I've checked it against the B7 A4 Bentley Wiring Diagram found here: https://wiki.bentleypublishers.com/....pdf?version=1&modificationDate=1306355851833
It would appear that there are several diviations from the B7 A4 wiring diagram, so don't go assuming it's correct or the same as the Exeo.
I'm still trying to find a proper Exeo wiring diagram.....
Left-hand side:
Left Indicator: Blue/Green (B7 = Blue/Green)
Left Brake: White/Red (B7 = red/black)
Left sidelight: Purple/Black (B7 = Grey/Black)
Fog light: White/Grey or Purple/Red (B7 = White/green)
Reverse: Blue/Red (B7 = Blue/Red)
Righthand side:
Right Indicator: Green/Yellow (B7 = green/black)
Right sidelight: ? (forgot to write it down!) (B7 = Red/Grey)
Right Brake: ? (forgot to write it down!) (B7 = Red/Black)
Reverse: Blue/Red (B7 = Blue/Red)
