OVERVIEW
Original three-pin housing for the camshaft adjuster connection
8L0-973-703 is the Genuine VW/Audi three-pin contact housing with a contact-locking mechanism for the assigned camshaft adjuster connection on the confirmed Audi A6 applications below.
The molded housing locates the electrical contacts and mates with the original keyed connection. Matching pin count alone is insufficient: the latch, keying, terminal type and complete part number must match the harness.
Technical details
- Complete factory number: 8L0-973-703.
- Factory specification: 3-pin flat contact housing with contact-locking mechanism.
- Design: molded electrical connector housing with keyed mating shape and locking feature.
- Quantity supplied: one individual connector housing.
This is the connector housing, not the camshaft adjuster or a complete wired pigtail. Terminals, seals, repair wires and the separate protective cap must be selected for the original wiring specification.
Common reasons to replace
- The housing is cracked or heat-damaged.
- The latch is broken and no longer retains the connection.
- The terminal-locking feature is damaged.
- The original housing is missing during harness repair.
- A previous repair used an incorrect connector shell.
Inspect the contacts, wire insulation, seals and mating component for damage or contamination. Diagnose the electrical circuit before replacing the housing. A new shell will not restore a corroded terminal or repair a broken wire.

Installation guidance
Follow the factory wiring repair procedure and isolate electrical power as instructed. Record terminal positions before removal, use the correct release tools and repair wires, and preserve the original circuit pin assignment.
Ensure all terminals lock into place and that the connector latches securely without stressing the wires. Complete the prescribed circuit and diagnostic checks after the repair.
Ordering information
