Audi Q5: Repair Kit for FlexRay Wires with Coating

  Note

  • The repair of FlexRay wires with coating can only take place using FlexRay wires with coating from the Parts Catalog.
  • Observe general notes for repairs on the vehicle electrical system. Refer to → Chapter "Vehicle Electrical System, General Repair Information".

A two-layer wire -1 and 2- with a 0.35 mm 2 profile is used as a FlexRay wire.

  • During repair work, both wires must have the same length.
  • When twisting the wires -1 and 2- together, the -A- = 30 mm routing length must be maintained.
  • While doing so, no section of wire may be greater than -B- = 50 mm without twisting the wires, for example in the area of crimp connectors -arrow-.

Audi Q5. N97-0261

  • Maximum exposed wire length: -C- = 100 mm.
  • Protect the area being repairs from the environment. Use a crimp connector with heat-shrinkable tube over the untwisted location being repairs and waterproof insulation over the exposed wire.
  • Mark the location of the repair with something suitable, for example, with yellow tape.
  • Repairing both wires is identical to repair just one wire.
  • Position both repaired location -arrows--A- = 30 mm opposite each other.
  • Crimp the cables with connectors.

Repair Kit for FlexRay Wires without Coating

  Note

  • The repair of FlexRay wires without coating can only take place using FlexRay wires without coating from the Parts Catalog.
  • Observe general notes for repairs on the vehicle electrical system. Refer to → Chapter "Vehicle Electrical System, General Repair Information".

Unshielded, twisted two-wire lines -1 and 2- with a cross section of 0.35 mm 2 can be used as FlexRay wires.

  • During repair work, both FlexRay wires must have the same length.
  • When twisting the wires -1 and 2- together, the -A- = 20 mm routing length must be maintained.
  • While doing so, no section of wire may be greater than -B- = 40 mm without twisting the wires, for example in the area of crimp connectors -arrow-.
  • Mark the location of the repair with something suitable, for example, with yellow tape.
  • Repairing both FlexRay wires is identical to repairing just one wire.

  • Position both repaired locations -A- = 20 mm opposite each other.
  • Crimp the cables with connectors.

0.22 mm 2 Wire, Repairing with Individual Crimp Connector

Procedure

- Free up the wire to be repaired 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 using a 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 connector, insert a repair wire section of matching length with two crimp connections. Refer to → Chapter "Repairing a 0.22 mm 2 Wire with Intermediate Wire Section".

Audi Q5. N97-0017

- Adjust the sliding stop in the Wiring Harness Repair Set - Wire Strippers -VAS1978/3- pliers jaws to 12 to 14 mm for the wire to be stripped.

- Insert wire end from front up to stop into jaws of pliers and squeeze the pliers completely.

- Open pliers again and remove the stripped wire end.

- Twist bare strands one-half turn.

- For the repair of a 0.22 mm 2 wire, use a small transparent crimp connector from the Wiring Harness Repair Set -VAS1978B-.

Audi Q5. N97-0016

- To press the crimp connector, use the Wiring Harness Repair - Crimping Plier - Base Tool -VAS1978/1-2- with Wiring Harness Repair - Crimping Head - .35-2.5mm -VAS1978/1-1-.

Audi Q5. N97-10491

- Slide the small transparent crimp connector onto both stripped, non-insulated wire ends on the vehicle-specific single wire and crimp them using crimp pliers.

  Note

Do not crimp wire insulation.

Audi Q5. N97-10490

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

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

Audi Q5. N97-0013

- 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 individual crimp connector should appear.

Audi Q5. N97-0010

  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.
