DPF EGR Delete
So I recently got the infamous p2002 code on my 2014 tdi. Assuming my dpf is shot based on the large amount of soot on the tailpipe. I am planning on installing the 3 inch hoodstack from darkside as well as obviously deleting the egr and asv and replacing it with the race pipe. My only question is I know you don't necessarily have to remove the egr cooler as well but what are some of the downsides of leaving it on for the time being and removing it in the future. I am also planning on using Tunezilla to tune the ECU but after doing some research I've seen that even after the tune sometimes there's still a flashing glow plug light or check engine light. Is that something that can be fixed by submitting a ticket through them? Just looking for as much guidance as I can get since I'll be doing this myself.
