Unshielded two-strand wiring - 1 - and - 2 - with a cross section of 0.35 sq.mm or 0.5 sq.mm can be used as CAN-Bus wiring.
-
The color coding of CAN-Bus wires can be found in the following table:
CAN High wire, powertrain
orange/black
CAN High wire, Comfort
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".
-
When repairing Bus leads, both wires must be of the same length. When twisting together wires - 1 - and - 2 -, length of lay of A = 20 mm must be
observed.
-
While doing this, no section of the wire, e.g. in area of welded 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.

For Volkswagen, no repairs are performed on fiber optic cables. For a repair, the entire fiber optic cable is replaced. Observe the following safety
precautions for this:

-
Fiber optic cables must not be sharply bent, bending radius must be no less than 25 mm.
-
Fiber optic cables must not be routed over sharp edges.
-
End pieces (lenses) must not be soiled or grasped with bare fingers.
