DEF system problems but no derate WHY??

Good video Joe. Took a couple notes to on pressure readings! The silicon carbide does seem to be performing better than the corderite DPF's. I think every single corderite single canister EcoFit has been breached when I service them. My pin drop testing indicates melting around outer peripheral. My theory is excess temp when truck drops to idle during mobile Regen. Can't get any official word from someone on engine side, but I think we are switching from graphite grey back to Alex Red.

Wow a color switch. That says something about reliability and support! Aftertreatment was such a learning curve for the OEM's and techs. It has come a long way. You will have to let me know what your favorite color ends up being ;-).

@@ENGINESHOPJOE The leading driver for the switch is actually resale. Extreme difference in price with all other variables besides engine the same. Yellow will always be my favorite color!

What’s DEF?

Diesel exhaust fluid Think of it as laundry soap to clean the exhaust gas so it helps to make the air we breath cleaner.
