How long did it take you from start to finish to complete this task?
Maybe about 1 hour - 1 1/2 hours of my time. DPF baking comes back the next day. And computer work with forced regen about an hour.
Dumbest fn thing I have ever experienced. A highly corrosive fluid being sprayed into and engine and components. Thanks EPA.
