OVERVIEW
Genuine VW/Audi 5N0-973-100-A is an individual 100-position connector housing for the original airbag-control-unit connection assigned this factory part number. The factory catalog identifies this version as the yellow housing with the violet seal/keying designation.
Technical details and what is included
- Factory part number: 5N0-973-100-A / 5N0973100A.
- Connector layout: 100 contact positions.
- Factory variant: yellow housing, violet seal/keying designation.
- Quantity supplied: one individual bare housing assembly.
- Contacts, repair wires, control unit and airbag components are separately specified.
The position count describes the housing layout and does not mean every cavity is populated in each original harness. Match the exact original number, keying, terminal system and controller connection. The separately catalogued blue, dark-grey and natural variants are different parts and must not be selected by position count alone.
Common reasons to replace
- The original connector body is cracked or broken.
- A damaged locking or contact-retention feature prevents correct assembly.
- The housing is damaged during a diagnosed harness repair.
- Inspection identifies physical damage at the original assigned controller connection.
Inspect the contacts, wire ends and mating control-unit connection separately. A new housing does not repair damaged wiring, correct an internal control-unit fault or replace a deployed airbag component. Diagnose the affected circuit and use the original repair procedure to determine all separately required components.
Vehicle fitment
The confirmed application requires the original 100-position violet-variant controller connection assigned this exact part number. Different controller or harness variants require separate verification.

Installation and service guidance
Follow the factory supplemental-restraint-system isolation, access and connector-repair procedures for the exact vehicle and controller. Record the original terminal positions and housing orientation before release, using the prescribed terminal tools and repair method.
Fit only the specified terminal system, renewing separately damaged contacts or repair wires as required. Seat the contacts fully and engage all prescribed locking features at the matching original controller connection. The housing alone does not provide a pinout conversion or change controller compatibility.
Restore the original harness route without strain or trapped wiring. Complete the factory reassembly, diagnostic and system-verification procedure after repair, including any prescribed fault-memory checks. Refer to the vehicle wiring diagram and repair information for the exact connector assignments.
