VW Audi 5-Pin Module Connector – OEM 6N0973755 / 6N0973855 | VAG Group
The OEM 6N0973755 (female) / 6N0973855 (male) are 5-pin connectors from Volkswagen's VAG Group connector family, used in module and sensor harnesses across VW, Audi, Škoda, and SEAT platforms. The 6N0 prefix identifies these connectors as originating from the VW Polo 6N platform, but they are cross-used across multiple VAG Group vehicles. The 5-pin configuration serves module power, ground, CAN bus, and sensor signal circuits. Available in Male and Female variants, bare or with 15cm pre-wired leads.
VAG Group connector part numbers follow a structured format:
| Segment | Meaning |
|---|---|
| 6N0 | Platform prefix — VW Polo 6N (but cross-used across VAG Group) |
| 973 | Component group — electrical connector housing |
| 755 | Female (socket-side) housing variant |
| 855 | Male (plug-side) housing variant |
This naming convention is consistent across VAG Group connector part numbers — the 755/855 suffix pair always denotes female/male variants of the same connector family.

The 6N0973755 / 6N0973855 connector is used across a wide range of VAG Group body and chassis control applications:
VAG Group connectors from the Polo 6N / Golf IV era (1995–2004) are now 20–30 years old. The original nylon housings become brittle with age and thermal cycling, causing locking tab fractures that allow the connector to partially disengage. Simultaneously, the tin-plated terminals oxidise in humid environments, increasing contact resistance. On VAG Group vehicles, a partially disengaged or corroded 5-pin module connector causes intermittent body function faults, CAN bus communication errors, and module fault codes that are difficult to diagnose without physically inspecting the connector.
| Code | Description | Typical Module |
|---|---|---|
| 01044 | Control module incorrectly coded | Door/comfort module |
| 00532 | Supply voltage — signal too low | Any module with power pin fault |
| U0073 | CAN bus off | BCM / instrument cluster |
| 01176 | Left front window motor — open circuit | Door control module |
Q: What is the difference between 6N0973755 and 6N0973855?
A: 6N0973755 is the female (socket-side) housing — typically on the module itself. 6N0973855 is the male (plug-side) housing — typically on the vehicle harness. The 755/855 suffix pair is a consistent VAG Group naming convention for female/male connector variants.
Q: What VAG Group vehicles use this connector?
A: VW Polo 6N/6N2 (1994–2002), VW Golf IV (1997–2004), Audi A3 8L (1996–2003), Audi A4 B5 (1994–2001), Škoda Octavia I (1996–2010), SEAT Ibiza II/III and Leon I. Cross-reference your vehicle's wiring diagram or ETKA parts catalogue to confirm fitment.
Q: Can I use VCDS/VAG-COM to diagnose a connector fault?
A: Yes. Connect VCDS and perform a full system scan. Multiple fault codes across different modules (door module, BCM, instrument cluster) appearing simultaneously indicate a connector or wiring fault rather than individual module failures. Inspect the 5-pin connector physically before replacing any modules.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
