Once again i have a problem, all because I had to go to the Dealership. 2012 DPF Delete, I returned to stock to visit the dealership. while in stock exhaust read 90% full, then went to Exhaust filter full see dealer, but i dont have a DPF. it started throwing codes, and even said reduced power. after i got back from the dealership i reinstalled my H&S Mini Max, all codes were cleared the CEL went out, but the message still remains "Exhaust Filter Full- See Dealer" how do i reset the message to remove it from the dash? I dont understand how it can be full if it dosent exist. i still have the same power as before.
