Re: Exhaust fluid system fault
if it has a turbo back straight pipe on it, there is no DEF injector or sensors on it and you will get the codes unless the tune is setup for Def delete.
also go back to the stock filter and get rid of that piece of crap k&n filter. they let way too much fines in and will dust the turbo and engine if you get into a dusty environment.
the stock factory filter will let in more air than the engine will ever need.
owner of almost to many fords.
If you want the moral high ground, make sure you're not standing on a hill of horsecrap.
