a friend of mine (e92 n53 2009) who lives in CZ but was going to a bmw garage in regensburg where they changed him (already outside a warranty) both hpfp and nox sensor at a fee below 100eur. I have myself n53 2009 and nox sensor was generation 01 so I guess yours would be generation 02 or 03....which was probably failure too. The info on generation 05 came from my mechanic and probably comes from some internal materials. The info about bosch nox sensors comes from a vw mechanic as they do not enjoy such a great business on exchanging that part...
