    ECU Code p0400

    This is the error code that i have on my car after just managin to get hold of some Diagnostics:

    P0400 Exhaust Gas Recirculation Flow Malfunction

    what will this point too? iv posted a few times about the same problem since iv bin dealin with it all week.. Any ideas? iv got a Clickin noise comin from the EGR valve as well now and again which when it does it means i cant start the car the next time without touchin the accelerator..

    Iv also got a Eco tek valve as well and recently adjusted it and that goes on the pope from the braking servo to the inlet manifold just after the non return valve basically on the vacume pipe that wouldnt cause the issue would it?

    eather clean the EGR valve (i think you need to replace the gasket when you do) or get a new 1 http://www.lmfvauxhall.co.uk/store/p...at=1568&page=1
