How was it done?... By an OEM with the proper Cummins certified machinery?.. and if so.. was the flow rate tested to be good after? .. or was it cleaned out by some other nefarious means?.

Was the DPF done at the same time?...

... and did anyone bother to do a proper Reset Procedure in Insite when it was re-installed?


did anyone bother to do a thorough egr Tune-up on the engine itself?

Has anyone bothered to see if the Doser injector is seeping/leaking fuel at idle?.
Same time I replaced the dpf I got the doc cleaned out ,also new dozer ,sensor , temp etc.
I replaced the egr and did the tune up . I noticed that the imap sensor was carbon
Packed completely.
