There is an indicator on the dashboard if the primary filter in performing poorly thus requiring cleaning or replacement. They said these vehicles were tested with the poorest diesel fuels in the Asian countries (e.g. China, India, Indonesia, Philippines, etc.) so they were able to devise this strategy to prolong the life of the diesel fuel injectors (common rail).
If this is true why is it that my 3Month old Innova wd 5,500 on ODO reading is having engine trouble hard/failed starting they suspected that it has somothing to do wd CRDi supply pump.Dont say that im the only one wd this problem were already 4 in Innova Thread and 15 in Toyota balintawak,3 Toyota QA and i dont know wd the other dealer. My freind also has this problem he got his unit from Toyta Otis.
