NOx sensor codes

[Phill80]

APR 2017 C Class 220 CDI with 56k miles. Check engine light came on yesterday, the attached codes came up on my local mechanics computer, its not an area he works with but says he will get a contact for me. In meantime just wondering if anyone has had experience of this, knows likely cost etc.? Only bought car at end of September @ 53k miles but unfortunately only a 3 month warranty, will be gutted if this is something major so soon.
