EGR block and engine light.

[Coldcomfort]

Hi all, I have 2012 CRD which I have done the EGR block thing. I was using a certain device that is supposed to prevent the engine light coming on. But that device caused intermittent almost 100% power loss. I live in country Victoria. Is there anywhere that I can take the car to have the engine computer tweaked to stop the light/error from happening? Cheers all.

You have two choices either use a scangauge or similar to clear the light and P0401 error on the rare occasions it happens OR drill a hole in the EGR block plate... there isn't a computer tweak that will stop it happening

I have a scan gauge and have been using that. But I was hoping that there was a permanent fix. Cheers, Brian.

Coldcomfort - Get a remap/postal (mild tune_20-22psi boost, AFR 20-22:1). Turns EGR off, think you are running positive pressure actuator need to rework that for higher boost.

The scanguage will clear the code, which should be P401. The ECU will log a few to start with and then learn. Mine would be lucky to do it once every couple of months and only takes seconds to clear. I didnt put any holes in the plates.

Good idea to block both ends, as it can crack around the exhaust side, which has happened to quite a few people and leak. Blocking both ends prevents that. I do run a higher boost, but it's only at idle the code should appear.

A 6-10mm hole will trick the ICU into thinking the EGR is std
maybe disconnect the battery overnight if possible as well

IMHO, do not drill hole thru egr blanking plate.

Drilling a hole is a waste of time. It's like going to a brothel for a hug. Why bother at all then.
Block the thing completely, live with the engine light coming on once in a while and that's it. Its simple.

I have heard putting a resistor in the pink wire from the MAF will disable the fault code, anyone done this?
