Volkswagen Touran Service Manual: Wire Break with Single Repair Point
Repair point with single crimp connection |
|
Free up wire intended for repair (approximately 20 cm to
both sides of repair point). |
|
If required, remove wiring harness wrapping using a folding
knife. |
|
|
|
|
Cut out the damaged section of wire using the Wiring Harness
Repair Set - Wire Strippers -VAS1978/3-. |
 Note
If, by cutting out the damaged wire section, both ends of
the vehicle-specific single wire are too short for a repair
using a single crimp connection, insert a repair wire section of
matching length with two crimp connections. Refer to
→ Chapter "Wire Break with Dual Repair Point". |
|
|
|
|
Strip the wire ends using the 6 - 7 mm wire stripper. |
|
|
|
|
Slide crimp connection onto both stripped wire ends of
vehicle-specific single wire and crimp them using crimp pliers. |
 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. |
