Safety Precautions For Wiring Harness And Connector Repair
CAUTION:
- Disconnect battery ground wire before working on electrical system.
- Before commencing repair work, always eliminate cause of damage, e.g. sharp body edges, faulty loads, corrosion.
- Exclusive use is to be made of yellow wires for wiring harness repairs.
- Each yellow wire and every location on the wiring harness wrapped with yellow insulating tape is a sign of a previous repair.
- Shielded wires such as e.g. RPM sensor and knock sensors may not be repaired.
CAUTION:
- Wires at individual airbag modules may not be repaired.
- If wires or connectors at airbag modules are damaged, the respective airbag module must be replaced for safety reasons.
- Repairs on airbag wiring set must be performed exclusively on vehicle-side using Wiring Harness Repair Kit VAS 1978A and original replacement parts (connector housing, terminals) in order to guarantee the repair quality required by Audi AG.
- Repairs are to be documented in the Audi Service Plan under "space for workshop entries" with a short commentary of scope of repairs, workshop stamp and signature.
- Any warranty claims to Audi AG are void if repairs on airbag wiring set were not performed using original replacement parts and Wiring Harness Repair Kit VAS 1978A.
