From what I was told these coolers have a 80% failure rate, which is horseshit if you ask me..

What did the dozer injector look like? when you removed it from the pipe was their a solid chunk of soot? I replaced one yesterday and when I removed it, it was completely plugged up where the hole is that the injector sprays into. I should have taken some pictures, it was horrendous

What does/was your soot load of the dpf filter?

Sorry for the late reply. Been a pretty busy last few weeks.

I haven't removed anything from the egr cooler, however I have heard about the dang near 100% fail rate on egr coolers though and I agree... complete BS!

My doser injector was pretty nasty. I cleaned it at first as it was completely covered with just a small hole where it sprayed, or leaked, fuel. It worked for a short amount of time, but then I started having frequent regen codes, dpf diff pressure codes, and when I monitored a forced regen, the temps were really low. Would take it almost 20 min to reach 850*. When I decided to replace it, it looked like the tip was clogged in the open position or maybe damaged. I have a pic of it after I removed it here:

I haven't checked soot load on the dpf before or after replacement, but diff pressure is was down in the 2.0 - 2.6 range on passive regen cycles now, from a constant 3 plus before. forced regens are at or below 1. I suspect I'll be needing a new filter soon, unless things work out where I can mandate'd' it.
