Hi all, just been asked to look, pluged in and pulled P2355:

"2355 - check system exhaust gas recirculation control - The air mass cannot be regulated - The air air mass is too large"

Clear the code and this comes back - engine idling - EGR position shows 5% on data, raised rpm and the EGR still shows 5%.

Thinking remove inspect EGR to see if stuck seized in place, was also told possible ait induction pipe/unmetered measure air entering the intake system after turbo.

Any view appreciated to work with - cheers Andy

With the scan tool, under active tests, can you command the EGR on and watch the EGR position and other relevant pids and see if idle changes or engine stalls?
