Had the exact same issues, just changed my filter and it was gross. Pretty sure it was factory.
Added 5 gallons of fresh DEF and did two regens and didn’t help.

How many miles on your truck? And why you wait so long to change this filter ?

You drive until somethings broken, then you fix it....
American moto, don't fix it until its broken. This is the American way 🤦‍♂️
