The wife is driving and the low tire pressure light comes on with run flat instructions but there's no flat. ( And we don't have run flats anyway)
Hmmmmmmm

fortunately we are near a BMW dealer so we drive in and they check it out and WALA they find a nail in the tire.
So off we go to wheel works (Not the cheepest place) and in about 1 1/2 hour total we are back on the road. End of tire adventure............
Moral?? None.... warning light works like it should.
