Allroad various error codes

[Bluemerlin]

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.

Any help greatly Appreciated

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?
