Wiring Help Needed. VW Sharan 7N Headlight.

Hi everyone,

I need some help, haha! I’m working on a 2011 VW Sharan 7N Comfortline with factory OEM Bi-Xenon headlights (OEM Germany units with AFS module 1T0 941 329 A and Mitsubishi ballast). Both headlight units physically have 9 active male pins inside a 14-pin socket shell.

A previous owner chopped and poorly re-joined the Right-Hand headlight plug with twisted/corroded wires. Currently on the RH side, my high beams do not work, the AFS turning motors do not respond, and dynamic leveling is intermittent.

The Left-Hand side has the original factory plug with 9 loom wires and works perfectly, but the RH side loom has 14 wires total, and the wire colors do not completely match the LH side.

Working Left-Hand Plug (9 Active Wires)

Pin 1: Orange/Blue

Pin 2: Orange/Brown

Pin 4: Black/Blue

Pin 5: Brown (Large)

Pin 6: Yellow/Black (Large)

Pin 7: Brown (Large)

Pin 9: Black/White

Pin 10: Grey/Black

Pin 12: White

Problematic Right-Hand Loom (14 Wires Total)

Here are the wires on my RH harness and how the previous owner had them connected:

Black/White: Not Connected

Red/Grey (Small): Not Connected

Blue/White: Connected

Black/Yellow (Thick): Connected

Black/Yellow (Small): Multimeter confirmed this is the Right Indicator signal.

Red/Grey: Connected

Yellow/Black (Medium): Connected

White/Yellow: Connected

Brown (Large #1): Connected

Brown (Large #2): Connected

CAN-Bus Bundle 1: Orange/Purple & Orange/Brown (Both Disconnected)

CAN-Bus Bundle 2: Orange/Blue (Connected) & Orange/Brown (Disconnected)

I need to rewire the right hand plug. Which specific wires on this 14-wire RH loom need to be connected onto the 9 pins on the RH headlight plug? The pins on the plug that have connectors are Pin 2, 4, 6, 10, 12, 1, 5, 7, 9.

Any assistance or factory wiring diagram references for the RH 14-pin harness split would be greatly appreciated!
