2009 Freightliner Cascadia

Oh man oh man
Got my truck back from Detroit I spent 6000 dollars
They diagnosed the problems with injectors,egr, throddle valve, dpf sensor, ADT harnest
All got it replaced I was so happy leaving the shop thinking these guys know what they are doing and my truck is 100%
Was I wrong  we got on a load same day drove aproxamitly 400 miles dpf lites again
Drove to a freightliner dealership and they did diagnostics after waiting 3 hours or so I was told injector for the dpf is plugged and they need to change it so I said fine again
Got back on the road within 100miles truck shutdown with dpf lights and got too level 5 soot level and it was impossible to drive
Long story short it was middle of the night I had to call towing Truck to take us to a local shop
We stayed by the shop all night until they opened and in the morning the mechanics checked everything and diagnosed my Doser block is bad so they replaced it and somehow forced it to regen
But by then I was already late to my appointment and had upset customer
So next day we got the load delivered and drove to flying J not far from delivery
And the dpf light came on again arggggggg so I called service again
They had to force it to regen yet again and I can't tell you all how frustrated and angry I am with this truck
