Do It Yourself: Yes
Rectification of issue happened on December, 2017. Full story here. I did not replaced it with a new part due to exorbitant price of this rare part.
End up, I had to replace it with a used part. Since the engine is quite rare in Malaysia, thus I have to resort using part from EW12 engine. It is the same part minus all the pipes. DIY needed to adapt the “heating element” section to the existing pipes.
Rectification was done in almost 2 hours due to tight space.
