Mitsubishi Triton 2012: Suction control valve

Asked by Chantell Gliddon

My 2012 Mitsubishi Triton GLX was a great car until March last year when the troubles started, and it has been in and out of the Mitsubishi mechanics since then. Some of the problems it has had are with the suction control valve and fuel rail, and a new motor had to be installed at 61,000 km. There have also been many more problems. Luckily it was all under warranty, but sadly that is going to be ending 2018. As I write this it is back at the mechanic's once again for the control valve, which happened when I was doing 110,000 km on the highway and the warning light went on and the car died. Is this normal? What options do I have?

If the suction control valve is worn or there is contamination present the fuel pressure will be affected and so will the drivability as a consequence. The car will sometimes go into limp home mode when this happens. It is a relatively common complaint on common-rail diesels, and the only thing to do is to replace the valve.
