I just replaced the pads and rotors on my 06 Mini S. I have been getting the low pressure light but after a reset it was fine.

Now I have the ABS light, Check Engine Soon light and stability/traction lights on? Don't really know what is going on here.. I took the pad sensor out of the old pads and reinstalled them in the new pads. Drove the car about 50 miles in 2-3 days and now I'm getting all these warning lights.

Any thoughts??
