Egr block off

[ranga071981]

Hi I am a newbie, Thinking of blocking off egr do i rely need to also fit a manual boost controller for turbo or can I leave it. All thoughts appreciated.
Cheers Ranga.

Most will block the EGR [read illegal] much better for the motor they say.
I personally fitted gauges to see whats going on under the bonnet, a manual
boost controller will complete your NADS set up. All you're doing is taking the "thinking"
away from the ECU.
Ive blocked my EGR and fitted NADS with no dramas at all

If its the direct injection motor you wont need to fit a boost controller. If its a Common Rail, then you more likely will need too.

Yeah its a 2012 DX common rail wagon mate just got it no mods as yet.

Yeah you will more than likely see limp mode issues, which cna be recitified by a manual boost controller.

If its a common rail fuel system you will need to drill a small hole around 6 to 8 mm into the block off plate , I no it sound dumb been that you are trying to prevent exhaust gas going back into you intake but if you don't have the hole in the plate it will go into limp mode due to the ECM seeing there was no boost drop when the ECM tells the EGR valve to open or work. The ECM is ment to see a drop in boost when the valve open's and by putting the hole there it lets the ECM see a drop in boost but been the hole is so small it will only let a small amount of bad hot crap air back into the engine. But if it's a old school fuel system mate go nut's block the bad girl off and don't stress about a boost controller she will be sweet.

@Hopkins mine doesn't have a hole and doesn't go into limp mode. What does happen is it throws a fault code which I clear in seconds with my scan gauge. 07

Your one of the lucky ones G. Personally I wouldn't bother with drilling a hole in the plate, just fit a manual boost controller and get the best of both. A totally blocked EGR and better turbo control.

First thing Id be buying is a Scan gauge

Like Growler and Mudski said. Drilling a hole in the plate is useless. It is only to stop the system from popping a ECU light on the dash. It does not send the system into limp mode.
My CRD had a plate and it popped up the light maybe once or twice a year... It does not affect the drive ability of the car at all. Its just a warning light. Simple reset with scan gauge.
Also definitely fit boost control setup on the CRD. The factory boost setup is OK. But can be tuned so much better with a manual control. Your car will thank you for it.
