hi i have a Fabia 1.4 16v AUB and i have had this fault code (P0403EGR control circuit) i have had it off and there is no green on the plugs and i have cleared the code several times but it keeps coming back.

Any help would be greatly appreciated.

First check Fuse 7.

Check you have a good earth on the brown/blue wire.

With the ignition on, check you have 12V on the black/red wire and 5V on the red/green wire.

The other two wires go to the ECU.
