I recently just got my cdl and purchased a 2015 Freightliner DD15 . Truck has been running smooth for the past couple months .
I have been having some def issues though .
How many filters does a DEF system have ? What is the difference between a DPF filter and regular def filter ?
I notice the dpf filters are very expensive versus just the regular def filter . Are there more then 1 def filter ?
Thanks for the help guys and other tips regarding the DEF system would be greatly appreciated .
