I think you will find things are not as simple as that with a modern car. If you just blank it off and throw it away, you will have faults flagged by the ecu and warning lights on the dash… Now an mot faiilure.

Idle harder - idle can't be hard or soft

There's an electric valve that keeps the EGR system OFF while at idle. The valve doesn't open the system until the engine reaches speed.
