Volkswagen Touran Service Manual: Wire Break with Dual Repair Point

Volkswagen Touran Service Manual / Electrical System / Wiring / Wiring Harness and Connector Repairs / Wire Break with Dual Repair Point

Repair point with intermediate wire section

Free up wire intended for repair at two points (approximately 20 cm to both sides of respective repair points).

If required, remove wiring harness wrapping using a folding knife.

Route the yellow repair wire next to the damaged wiring harness and cut the repair wire to the required length using the Wiring Harness Repair Set - Wire Strippers -VAS1978/3-.

Cut damaged wire section from the vehicle-specific single wire.

Strip the wire ends using the 6 - 7 mm wire stripper.

Slide crimp connection onto vehicle-specific single wire at one side and onto repair wire at the other side.

Crimp the crimp connection at both wire ends using crimp pliers.

Repeat this procedure at the other repair wire end.

Note

Always be sure to use the correct crimping slot for the crimping connection used. Refer to → Chapter "Crimping Pliers with Insert".

Do not crimp wire insulation.

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

Place the Wiring Harness Repair - Blower - Shrink Element -VAS1978/15A- on the Wiring Harness Repair Set - Hot Air Blower -VAS1978/14A-.

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

Caution

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 gun.

Always observe operating instructions of heat gun.

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.

In the event the repair point was previous taped, this point must be taped anew with yellow insulating tape after repairs.

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