I was looking to upgrade the bulbs in my headlights to LED and when removing the headlight unit was horrified to discover the degraded wiring on the harness plug.
Sure, the lights were working fine, but the state of the wiring and the plug meant its days were numbered.
This prompted me to order some new, third-party harnesses from Amazon which were around €13.00 each.
However, when removing the old harness and installing the new one, the light did not work and the dashboard gave me an error saying to check the lights, so I assumed it was the harness.
After discussing with some VW forum members, I ordered OEM harnesses from the local VW parts garage at cost of €46 each (inc tax).
