RE: DEF pump sound getting louder
DEF and DPF are OEM parts. Could be different unit on Volvo or Freightliner or Pete or no DEF/DPF unit at all. This is why it's not in Quikserve.
Check the DEF dosing nozzle. If you have Insite run the test for DEF injector. If nozzle is plugged air will not come or restricted to in DEF line.
