I have a 90 S2 and brake wear warning light came on.

Pads have plenty of life and only 13k mi old. I inspected all pads inner and outer and the wear sensor is at least 4mm away from touch the rotor.

I am getting 0.3ohm on both sensors left and right. So it isn't the sensors I don't think.

I cannot disconnect the harness on the chasis that the sensors are connected to. They appear to be super tight connectors.

Any other way to figure out what is wrong?

I tested the harness from the engine bay harness (located near the shock tower). Both sides I am getting 0.6-0.7 ohm which means the harness and sensors have good continuity.

Not sure how to proceed now. Should I change the sensors anyways to see if that helps? I doubt it would

Took out the brake wear sensor and it fell apart in my hands. Ordered a new one. Hope that solves it!
