Audi 16-Pin LED Headlight Wire Harness Connector – Female OEM

This 16-pin female headlight connector is designed for Audi vehicles with advanced LED matrix or laser headlight assemblies. The 16-pin configuration integrates low beam, high beam, DRL, turn signal, AFS (Adaptive Front-lighting System), headlight leveling motor, and LED driver module circuits in a single connector. Available bare or with 15cm pre-wired leads.

Key Specifications

Pin Function Overview

A 16-pin Audi LED headlight connector typically serves: low beam LED driver (2 pins), high beam LED driver (2 pins), DRL/position light (2 pins), turn signal (2 pins), AFS motor (2 pins), headlight leveling (2 pins), and LED module communication/power (4 pins). Verify your vehicle’s wiring diagram for exact pin assignments.

Why LED Headlight Connectors Fail

Audi LED matrix headlight connectors are exposed to road vibration, thermal cycling from high-power LED drivers, and moisture from the headlight housing. Terminal oxidation, housing stress cracks, or melted connectors from LED driver heat cause intermittent headlight failures, AFS warning lights, or B-code fault codes. Replacing the connector restores full headlight circuit integrity and eliminates ghost lighting faults.

Variant Guide

• Female – Bare 16-pin housing with terminals for custom wiring repair
• Female 15CM – Pre-wired with 15cm leads for direct splice-in installation

Installation Steps

1. Disconnect the vehicle battery
2. Remove the headlight assembly to access the harness connector
3. Release the locking tab and unplug the original 16-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the headlight and verify all functions (low/high beam, DRL, AFS, turn signal)
6. Use VCDS or OBD11 to clear any B-code headlight fault codes

Frequently Asked Questions

Q: What Audi models use a 16-pin LED headlight connector?
A: Common models include Audi A4 (B9), A5, A6 (C8), A7, A8, Q5, Q7, and Q8 with LED matrix or laser headlight systems. Verify connector shape and pin count before ordering.

Q: What fault codes indicate a headlight connector issue?
A: Common codes include B1600-series headlight circuit faults, AFS motor errors, LED driver communication faults, and DRL open circuit codes on Audi VCDS/OBD11 diagnostic systems.

Q: Can I use VCDS to diagnose headlight connector faults?
A: Yes. VCDS (VAG-COM Diagnostic System) and OBD11 can read Audi headlight module fault codes and confirm connector-related circuit faults.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
