Resetting brake wear indicator light on dashboard
I have an 01' jetta too. Mine has the sensor. My light came on when my pads got so thin the heat burned the wire off the pads and it was just left hanging there. Take another look for a stainless steel bracket by the caliper which would be holding the harness. You might find a dangling wire which use to be on your old pads. The wire/plug comes right out of the back of the pad near the edge, so you couldn't miss it. 3-4" long.
