Volkswagen Polo Service & Repair Manual: CAN Bus Wires, Repairing

Unshielded two-strand wiring -1- and -2- with a cross section of 0.35 mm2 or 0.5 mm2 can be used as CAN bus wiring.
The color coding of CAN bus wires can be found in the following table:
 

CAN Bus Wires, Repairing

CAN High wire, powertrain orange/black
CAN High wire, Convenience orange/green
CAN High wire, Infotainment orange/violet
CAN-Low lead (all) orange/brown
 
Repairs on CAN-Bus wires can be performed with repair wire with matching cross section and also with twisted wires “green/yellow” or “white/yellow” from Parts Catalog.
When repairing Bus leads, both wires must be of the same length. When twisting together wires -1- and -2-, the lay length of -A- = 20 mm must be observed.
While doing this, no section of the wire, for example, in area of crimp connectors -arrow-, may be greater than -B- = 50 mm without twisting of the wires.
Wrap repair points with yellow adhesive tape to mark a performed repair.
