What can cause doc face pluging? No fault codes. Doc face pluging happened about a month ago. We cleaned it by running the engine 5-6 hours Diagnosticlink connected. It was cleaned. Now again pluging happened. We have checked injectors, turbo, air filter. Everithing is ok. Any ideas?

How many miles on the truck? I've heard that the catalyst can wear out, which would mean not enough oxygen being produced during regens. Seems like regens would start failing for lack of heat if that were the case though.
