NOX sensor faulty?

hi, been having trouble with my car and the eml has been coming on, had someone to look at it and they said it was a faulty nox sensor because of the code they got,
which is 30EA which points to a faulty nox sensor.
ive had someone at a independant bmw garage check it and they said it was a faulty 02 sensor, lambda sensor? , so ive has this changed and the same code has came up about the nox sensor being faulty....
ive read that these can regen? can i do some motorway miles to make this so or maybe the wrong lambda sensor has been changed....
any advice would be great
