I’ve just ordered a blank egr gasket for my 2012 yd25. Will I get an engine light after doing it?

I'm going to say its highly unlikely.
It has been reported that some models have a flow sensor.
I doubt you'll have issues

Did the same on my 8-port YD25 (2013 engine in a 2012 D40), no check engine light and no codes.

I did the egr delete on my 2008 yd25 d22, no issues or engine lights/codes. There is no sensor in my model to trip a code.
just to clarify. these, or any small diesel that i have seen, do not have an egr flow sensor. soot would foul up a flow sensor in seconds. (some have egr temp sensors)
they detect egr flow from the change in airflow using the maf sensor and they all have maf sensors. open the valve, detect the drop in air flow. the more egr is used the less air that gets used. it just comes down to what the egr flow rate is and how sensitive the software is.
I used a hand cut piece of stainless steel, planted a couple of trees instead.
As I understand it the EGR only opens at low power settings anyway, so it's more of a compliance device than an actual emission-reduction thing.
Happy to be told otherwise though...
My EGR system is fully functional but for a blanking plate and a U-shaped hose that cuts off the EGR cooler- it's a Spanish-build 140kW engine, I believe the D22 setup is different.
I was told I might have to drill a small hole in the plate, 3mm or so, to prevent error codes but that isn't case and the EGR pipe remains completely blocked.
None of the magical power/economy improvements have manifested, but there's less smoke when the throttle is wide open and I hope less sludge in the intake ports.
