    Default EGR valve question - 2.2 Direct

    Evening folks

    I've got the P0403 EGR circuit malfunction code showing. I guess it's probably the solenoid.

    If I blank the EGR and Tech 2 it 'out', should this solve any EGR related issues?

    Also, does blanking the EGR affect your emissions?

    Ask "rushy" as he usually knows these things, but I would guess that you either need to get the EGR functioning as normal by cleaning it and freeing up the soleniod or blanking AND Tech 2 deletion.

    Trim : SRi (VXR Styling)

    Engine : Z19DTH (Re-mapped)

    Year : 04

    Mileage : 110k

    if its anything like the non direct it doesn't need tech 2 delete... but it does need to function.

    When i blanked mine i knocked it and the valve jammed so it threw up the dash symbol, one i gave it a clean and a tap and re fitted all was well...

    I think we're all agreeing...it either needs:-
    1) to function properly, so cleaned and solenoid working OR...
    2) blanking and Tech 2 deletion.
    On the 1.9cdti, (1) is simple but repeatedly required as a regular service dependent on driving style and journey type, but (2) is permanent! (2) also improves performance and MPG.
