Retrofitted heated seats
Posted: Wed Dec 10, 2025 3:23 pm
Hi,
I've installed Golf heated seats (alcantara ones). I connected wiring. Wires from AC shows 9V when toggling between stages, 0 when its OFF on AC. white BCM cable is connected to pin21 in BCM (0186) connector. Added installed seats to BCM coding. And it isnt working. When engine is working I'm getting 9V on main heating cable. (not the supply from fusebox it gets 12V). In VCDS im getting ConsSwOff 0 sometimes 1.
Any ideas?
