This harness converts your MK7’s 10-pin halogen headlight wiring to support OEM 14-pin Bi-Xenon headlights. It enables all core lighting functions so you can retrofit OEM units without cutting or splicing.
 
Key Features
Adapts 10-pin halogen wiring to OEM 14-pin Bi-Xenon headlights
Supports low beam, high beam, DRL, turn signals, and markers
OEM-style connectors and proper gauge wiring
Plug-and-play — simple install with clean fitment
Coding required (instructions available in PDF)
 
AFS / Auto-Leveling
This harness does not support AFS (Adaptive Front Lighting System) or auto-leveling
If left enabled, you may see fault codes — disable AFS and auto-leveling in coding for a clean scan
If you need AFS and full headlight functionality, a separate AFS-specific harness is available
 
Fitment & Compatibility
MK7 / MQB (halogen 10-pin wiring) → retrofit OEM 14-pin Bi-Xenon headlights
Not for MK7.5 / facelift LED headlights
Not for aftermarket headlights (this is for OEM 14-pin units only)
 
Important: If you’re unsure, send me photos of your connectors or your VIN and I’ll confirm before you order.
 
Why Use This Harness
MK7 halogen cars use a 10-pin connector, while OEM Bi-Xenon headlights use 14-pin. Without this adapter, they won’t plug in directly. This harness makes the swap possible and keeps the install clean and reliable.
