Good pics buddy , I did see a YouTube thingy of those deposits being dissolved by hot water before reconnecting the bits .

Yes. That’s all I used. Hot water in a tub and dipped the injector in repeatedly. The crystals dissolve and look like a milky residue. Constantly had Nox errors until I cleaned the injector and the inlet. I now clean it every 6 months or so.

Good job buddy , that should help a lot of other people as well .
