EGR Delete without remap

Hi,

Im having problems with my EGR valve leaking. When Fully closed it leaks boost pressure.
I have disassembled completely and cleaned it numerous times but I still have this problem.

I fitted a blanking plate but I'm obviously getting the engine fault light.

Is it possible to have the EGR delete software mod without having a full re-map?

Thanks!

I think he was aiming at "no power gain"

I'm aiming at stopping my engine management light showing when I have the EGR blanked without the cost of a full remap.

Where is the sensor that causes the engine management light to come on? I'm assuming you've blocked the inlet to the EGR - as I have, but I was wondering if the sensor is within the EGR itself so by blocking the outlet side the engine management light would stay off?

No, in a nutshell, ECU measures airflow at the intake (before turbo), and if the airflow doesn't change as it should when EGR is active, engine management light comes on...

- are you sure your right? I thought it was the MAP sensor the inlet manifold that could tell if the EGR valve was operating correctly?

MAP sensor measures the air pressure inside the manifold and has almost nothing to do with EGR functionality

It is the MAF sensor that measures the airflow into the engine...

Does the turbo have an electronic wastegate?
I've read in previous posts that the EGR acts as a kind of wastegate to reduce exhaust pressure through the turbo and constant spooling under low boost scenarios.
