On your question, if the doser was replaced and the ahi adaptive factor reset and the fault came back this is what will need to be done. The 7th injector is supplied via the AHI module. This is located at the bottom rear drivers side corner of the block. There is a 1/4 air line going to it. Remove this air line and make sure there is no oil, water, or debris. If there is then service the air dryer and replace the module. If the air is clean and dry put a gauge on the line with the vehicle aired up and make sure it is between 34-40 psi. If not then replace the regulator that mounts to the air dryer. If the pressure is fine then replace the ahi module.
