Unplugging EGR Valve?

Hi all. So read on another forum last night about being able to simply unplug the connector for egr valve on 06+ powerstrokes while the motor is shut off and the valve will stay closed basically acting as a block. It also said it would only throw a soft code. Did it last night just to try it, drove around, everything felt good and no CEL. However, after start up this morning, CEL comes on. Just wanted to make sure this is legit until I can afford to buy an actual delete. Thanks for your help.

Its not goin to stop the flow of hot exhaust gasses and coolant from flowing through the egr cooler, it's simply just not going to let the exhaust gasses go through the intake to be recombusted.

No, its not legit.
Unplugging the EGR valve is NOT going to stop the exhaust flow from entering the intake (or any coolant that has leaked from a failed EGR) under all conditions.
The valve can (and will) be effected by differing boost pressures, forcing the valve open.
If it was that easy, nobody would buy an egr delete.

The code that sets off the CEL is not a code that gets thrown immediately. It can take some time for the CEL to light-up. After installing my egr delete, I did not get the CEL for almost 2 weeks after.

Also, unplugging your EGR valve with certain ECM strategies can cause issues with the clutch fan and VGT operation.
