its not clogged its cracked. all you can do is delete it or replace it
Is it definitely cracked? It couldn't be anything else? Asking because I cleared the same code by replacing the (N18) EGR valve. I've been assuming that replacing this valve is just a short term fix...but if the dpf is cracked, does it make sense that the code cleared? Or Maybe it just hasn't had time to be triggered again?

Doing a delete costs about as much as fixing the system back the way it's supposed to be. But theoretically you don't ever have to do that again. Whereas if you fix it back the way it's supposed to be, it could possibly fail later on again. Delete parts and tunes are getting hard to come by though and you're in California which checks emissions. That limits you to fixing it back the way it's supposed to be or selling the car or moving. In my experience there's very little that can be fixed for $100 on a car. Concerning problems and issues like this. Sometimes you get lucky though.

I see. I'm just very lucky that I'm still registered in a VA county with no emissions. Yet.
