Sounds like the shotgun approach for repairs. A bad injector could be dumping excess fuel causing a too rich condition making the black smoke and maybe even cause the high temperature. As for the particulate filter and oxidation canister maybe you should wait and see if they clean themselves once the fuel issue is addressed. As for the turbo maybe it s fine once the fuel flow is addressed. If you can't do your own trouble shooting, have them proceed 1 item at a time, starting with the known problem, the injector.
Sounds logical, I think the injector needs replacing for sure. Still puzzled over the fan clutch and not sure how it works, but strange how it did not work on a 8 mile trip from my storage hangar to my house, but worked fine from home for 75 mile trip, but messed up on the return trip within 10 miles of trip.
