Repair A Wiring 0.35 Mm 2 Or Greater With Intermediate Wire Section: Procedure

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

-- Free up the wire to be repaired at two places approximately 20 cm on both sides of the repair point.

CAUTION:

Risk of damaging the electrical wires.

Expose wrapped wiring harnesses carefully.

-- If necessary, removing the wiring harness wrapping.

-- Route the yellow repair wire next to the damaged wiring harness and cut the repair wire to the required length using the :VAS1978/3 .

-- Insert the vehicle-specific single wire end from the front into the pliers jaws as far as the stop and squeeze the pliers together completely.

-- Open pliers again and remove the stripped wire end.

-- Repeat the procedure on the other end of the vehicle-specific individual wire.

-- For the repair, use two suitable crimp connectors from the :VAS1978B .

NOTE:

Always be sure to use the corresponding crimp connector and the correct crimping slot for the crimping connection used. Refer to CRIMPING PLIERS WITH INSERT .

Do not crimp wire insulation.

-- Use the :VAS1978/1-2 to press the crimp connector.

-- Repeat this procedure on the other wire ends.

NOTE:

Do not crimp wire insulation.

After crimping, crimp connections must be heat-shrunk using hot air gun to prevent moisture penetration.

-- Insert the :VAS1978/15A on the :VAS1978/14A .

CAUTION:

Risk of damaging surrounding components.

When heat-shrinking crimp connections, be careful not to damage any other wiring, plastic parts or insulating material with the hot nozzle of the hot air blower.
Always observe operating instructions of heat gun.

-- Heat crimp connection using the hot air blower lengthwise from center outward until it is sealed completely and adhesive comes out the ends.

This is how the completed repair location with the inserted wire and two crimp connectors should look.

NOTE:

Make sure that crimp connections do not lie directly next to each other when several wires need to be repaired. Arrange the crimp connectors at a slight offset so that the circumference of the wiring harness does not become too large.

If the repair point was previous taped, this point must be taped again with yellow insulating tape after repairs.

Secure the repaired wiring harness if necessary with a cable tie to prevent flapping noises while driving.
