 I am chasing a CAN BUS problem (2012 C4 B7) and I need to break up the network to isolate the issue. Does anyone have a routing diagram/schematic or know where I can get one, that shows where the harness runs, location of connectors and the location of all the control modules on the network.

Thanks for any assistance.

Jeff

 There are some on the site: - Click Here -

However, they are difficult to understand and the colours are in French, e.g. N = Noir/Black; J = Jaune/Yellow etc.
