You can disable the light via vag-com.
If you got plenty of pad, its usually one of two things wrong:
1) The sensor cable has broke
2) The pads do not have a wire going through them which breaks as your wear your pads down, causing the light to go on. It does however turn on quite early on your brakes even when there is still some good life left in the pads (good thing in a way as people usually don't change them ASAP and will do several more 1000 miles before they bother a change)
