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??

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