2006 My 407 diesel vehicle sometimes cuts

h. my friends are cutting and shaking the gas suddenly while driving at different speeds and revolutions exhaust emission failure engine control system malfunction gives high pressure malfunction, they usually do not show malfunction, they don't use low fuel, the amount of fuel does not matter. I changed companies, they said that there is dirt in the warehouse, I went, I cleaned the float tank, no malfunction is going on, my car takes 185 thousand anthem at once, no illumination is wrong, the battery passes for 3 years, I am afraid of it.

There are 2 options according to the fault diagnosis.

they say crank sensor I think it's a common malfunction in 407 ... you will just replace it if it is singing 70-100 tl piece or even I have one ... there may be a rail sensor (common rail pressure sensor) but its malfunction is a little different ... depolliation Does the system fail like faulty?

Egr valve may be full.

Thank you very much for your attention to friends, I will talk about what you say in private service with masters individually.

I really did the things you said to the master that it was the exact solution.

I think it is valid since it is the same engine
