Hi,

I've found one already (It's under the hood).
But where's the second one? How to access it?

Thanks!!!

The location of the first one is in top right corner in this photo (near the red cover):

There is another on just after the SCR converter, mid vehicle where the Urea injection is applied. You have to remove a heat shield to access the sensor pack.

And another questions: are both NOX sensors the same (same part number? same cable lengths? same controller unit?)?

Yes you need to go under the car and I am not sure if the part numbers are the same. I know when you get a new one for either the part number is different due to the part being superceded.
