Hello I have the same code sa 0 spn 5443 fm7 and have checked the hydrcarbon doser and its clean and clear! The soot level gauge says soot level s low. So would i still need to clean the dpf filters? ot is this just a hydro carbon doser module that is bad? and a notT to all the drivers out there. THERE IS TWO DIFFERENT DOSERS A DPF DOSER FOR DEF FLUID AND A HYDROCARBON OR DIESEL FUEL DOSER OR 7 TH INJECTOR IF YOU WILL.EACH RUN BY THEIR OWN MODULES..
