My research found that the def dosers are nearly universal, pretty much all made by Bosch. They are not OEM component, they are specific to your Engine (ESN) and aftertreatment system, but in reality I think all the OEMs use the same Bosch part. Pull the DEF doser valve off and compare the manufactuerers part numbers, try a google search. I found some cheap ones on amazon, but the one I tried leaked from day one. If you're keeping the system intact I would just spend the ~$400ish and get a genuine one that probably passed quality assurance.

The AHI module goes through various self-checks during the operation of the engine. If the system detects an issue, it will automatically cause an active fault code related to the AHI module or 7th injector. The fault code will sometimes lead you to believe that the problem is with the 7th injector; however, in reality, there is an issue with the AHI module.
