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!

Yes!

Ok so far so good, how much does it cost and where can I have it done?

Yes!

How do you re-write alterations in software without a remap?

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...

OK thanks, guess I need a remap then!

- 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?

 

[TribesMan]

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...

 

[nick9one1]

Ok that makes sense!

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.

The boost are electronically controlled but the wastegate isent electronic.
