Honestly just ignore the brake pad light. it has nothing to do with the issue. It is on cause it sees a brake in a wire to any of the pad sensors. It could be at the pad or anywhere along the path.

With that said, given that you have both and the pad sensors are new you very well could have a break in the wire/connector. Been 4 years since I dealt with similar issue and I dont have a car on a lift right now to get a picture, but the 2 sensors go into a single harness at each wheel. These can get chaffed/cut/rubbed. Very common cause porsche makes a repair kit for it. When I ran into this my durametric did say which wheel sensor it wasn't reading.

Again, I dont care about brake pad sensor on my cars. I dont even use them. I just cut the end off, connect the 2 wires and it thinks the sensor is there. All it is is a contact sensor so it doesn't really matter.

I would get it in the air, go to each wheel, pull the wheel sensor and ohm it out. FSM should have the specs or it's somewhere on the interwebs.
