00 2.0 Fault Code P0400 Critical System Malfunctio - tomandjerry56
The Engine Warning Light came on a couple of days ago, so put my Zafira in to the garage. Have just got the car back and they say that a fault code of P0400 Critical System Malfunction 2 was showing when plugged in to their computer.

The garage have advised speaking to a Vauxhall Dealer and finding out more info on the code.

Can anyone advise what this code means and will it be an expensive/difficult job to put right??

probably an EGR problem,judging by the first couple of posts in that thread.

hi
the fault code is for the gas recirculating valve and the valve will have to be changed after some more testing
