Hiace High Roof 2982cc Turbo 2008 Model

DEAR FRIENDS,

My name is ganny from singapore.

I bought a toyota hiace.

Make/Model: Toyota Hiace High Roof 2982cc turbo 2008

Engine no: 1KD1756066

This euro4 exhaust system design comes with the Dust Particulate Filter(DPF). It keeps getting plugged-up causing the Electronic Computerised Unit(ECU) to perform DPF "force burn" sequence automatically, but the butterfly valve located in the exhaust piping keeps jamming up and sends signal to the ECU that it is not in correct positioning.

Therefore, ECU send an alarm display in the control panel "yellow engine fault alarm" and limits the fuel supply, preventing the vehicle from travelling at normal speed.

In order to clear the DPF, manual "force burn" it have to be done in a vehicle service workshop. And this problems keeps repeating. Each manual "force burn" cost me about $SGD150.00 and some 6 hours lost of use.

The workshop blamed the plugging of the DPF to the high sulphur content in the diesel, and said, Spore fuel stations have not comply to Euro4 diesel standards yet.

May be you have a clearer understanding of how the EURO 4 exhaust and its Dust Particulate Filter works.

I'll most appreciate if you can share the knowledge with me.

Some questions i would like to ask:

1) What specification of diesel must this model use? example: sulphur content.

2) How does this model automatically cleans or "burn" the carbon or dust trapped on its DPF?

3) Is there a device or switch that can be installed in this model to manually perform the DPF cleaning function?

I am very glad that i came across this forum page.

I hope, i can get this problem solved.

THANK YOU.

warmest regards.
