    No need as the devil valve will remain shut .

    You only need a blank if the egr is faulty and is partially stuck open .

    yes but does the valve being shut not let any gases pass 100%?

    If it did it wouldn't be much of a valve and issues relating to it would be common .

    Who ever is doing the remap should be competent enough to tell you...

    If they can’t, you might want to rethink to letting them loose on your car...

    Egrs are usually "blanked off" electronically. You can't simply blank them off with a plate. There's a very long running thread on here about this.

    who told you that? you can fit a blanking plate where the exhaust gas goes to the egr then have it mapped out

    Yes , most common is a two bolt flange end of an egr feed pipe .

    I've a 1.5mm slip in blank in the VeeDub at the base of the feed pipe which meets the exhaust manifold , this is optional as it just prevents the tube from needlessly filling up with exhaust gasses .

    The following applies to sophisticated car mamagement, such as Mercs from this century. I've discussed this with a highly recommended remapper, and this was their view.

    You can physically put a blanking plate usually between the block and the EGR pipe.

    If this is done and the EGR valve is not mapped out, it will throw EML errors.

    If electronically blanked, the valve will simply remain shut, and the remap will delete the EGR process and so no error codes.

    Only in the event the EGR valve is blocked open/faulty, would you need to fit a blanking plate, and this is because it is cheaper and quicker than fitting/fixing the EGR valve, which will be of course allowing constant EGR vent.
