    Hi All,

    First post here so hopefully you can help. I am receiving the following error codes.

    17963 - Charge Pressure: Maximum Limit Exceeded
    P1555 - 35-00 - -
    16487 - Mass Air Flow Sensor (G70): Signal too High
    P0103 - 35-10 - - - Intermittent
    17831 - Secondary Air Injection System; Bank 1: Insufficient Flow
    P1423 - 35-00 - -
    17819 - Secondary Air Injection System; Bank 2: Insufficient Flow
    P1411 - 35-00 - -

    I also seem to have very slow engine performance and under heavy acceleration the abs and yellow triangle light come on, till i lift off. After this the suspension light stays on.

    I have logged a couple of things, the waste gate duty cycle is almost always 0% and the actual boost seems to be a lot higher than specified, See graph below.

    petrol engine hmmmm.
    over boosting. try cleaning the boost pressure sensor? are both the wastegate/dump valves working not split in side?

    air injection system problem will be a different fault i think.... are the vac pipes to both egr valves intact?
