@AMI0755 your fit got a problem with egr valve or egr system? what is the error code you got? i think your fit's egr valve is control electronically by ecu, maybe the egr valve was clogged by carbon deposits or it malfunctioned

@ Mr.Don our vehicle is mazda bongo common rail type van.so we got some problems with dpf,using super diesel is not a solution for dpf filter block, so that is the best solution for dpf problems in sri lanka our van done 40000km after dpf filter drilled. @ crosswind i don't know about Sylvi Wijesinghe

you can't remove the filter, but you can drill a hole in the filter,after that fix the filter and remove dpf indicator bulb from dash board and reset the ECU by disconnecting battery terminals.Please get some help of mechanic. after doing is it your engine has a turbo i think fix a turbo timer is better. RF6C engine is very good in fuel consumption.

reason is DPF system. Also mazda bongo got the DPF & clean diesel filter. DPF filter is supporting in sri lanka but clean diesel system not supporting in sl because the quality of diesel. our vehicle get this matter, we try few times to fix this matter but we finally remove the DPF element & disable the DPF system.
