Like the title states, i'm looking for answers when it comes to sneaky deleting my EGR cooler. I cleaned my egr valve last weekend and saw that it was wet and cakey. My cooler has developed a small hole. I've been waiting for this to happen, and would probably put a BPD cooler in and build an intake dummy egr valve/plug, but money is tight and I found a core to weld up and throw it back in to sneaky delete. I'm fully expecting a CEL for low egr flow and have an SCT with custom tunes with the CEL already tuned off for EGR delete.

I have to smog next year and really don't want to shoot myself in the foot here. with the pcm tuned, will it throw a red flag when they hook up to the obd2 port to scan for soft codes? I have a stock tune with the light shut off, so it shouldn't fail the smoke test, the cooler and valve will be intact for the visual, i'm just concerned about the code scan.

any help would be greatly appreciated!

I believe as long as the computer doesn't have codes cleared for a few days before the test you should be good, turned the EGR off with the SCT doesn't set a soft code

Can I ask what the smog test entails where you live? In Washington State, they do a quick snap test, no visual or computer check. They only check for smoke out the exhaust.

As far as I know, it's a visual inspection, obd2 scan for dtc codes, and a 3 try snap test.

Yup, thats it here in Ca. But if the CEL does come back on while your scanner is disconnected you will get a fail

Is yours tuned? Deleted?

nah, but I have had to smog it already here in Ca. My smog shop is very friendly and gave me the run down. Said the state tells them to look for the EGR, had a picture book even, also at the bolts on the CAT even to see if they have been used recently (ie: putting in a CAT test pipe in between smog certs) it's so they can tip off state officials about possible CAT removal offenders. I have a 4" turbo back with muffler and CAT, I have a monitor plugged into the OBDII and they had me unplug it for 15 mins before testing.

The current testing equipment cannot comunicate with CAN bus equipped vehicles so yours will be exempt from the OBD scan. So as long as there is no CEL you are OK.

Apparently the ARB would like to update the smog station equipment eventually but I just got smogged last month and it was still just a visual and snap test... unless there is updated equipment and the place I go to still has the old hardware, who knows.
