    T5 Intermitant Boost Issue HELP struggling

    T5

    Had a new egr just fitted but still some faults remain

    4795 - Mass Air Flow Sensor (G70) BUT brand new unit fitted also.

    5171 - Boost Pressure Regulation ?

    Fault is very intermitant only seems to do it once a day

    Hi sheepie,
    Genuine MAF? Have you made sure all the pipework and vac hoses are in place after the EGR change? Was it a genuine EGR by the way?
    Regards HMC

    Verify requested versus actual boost and that boost control is achieved at all loads.

    Maybe a leak as HMC aforementioned or maybe plugged exhaust or Intake or maybe wastegate stuck/unadjusted/linearized.

    Genuine egr and maf all hoses look intact and fault is so intermitant i cant catch it doing it . Do you think it is worth changing map sensor ?
    I done a dpf regen so think exhaust is free plus no fumes coming from back of turbo that happens then it becomes clogged .

    egr was blocked up bad and so was the pipe work feeding it wonder if i have missed something

    What condition does this happen at, general driving, full load acceleration etc? Have you checked for sticking waste gate mechanism/veins?
