You'll be fine my 2012 has done 19,000km without a hole.
I believe it may be just the 3.0L V6 that needs the hole.

That's the one! Or if you find those bolts hard to undo like i did due to corrosion, there is a flange in the middle of the pipe, works just the same.

Erm......what model is that on because the place I installed my plate looks like this:
Is it just a different model or have I had a "rodney you plonker" moment and installed it in the wrong place.

Hi Guys,
I have the STX 550 with the V6 turbo diesel and have had a couple of issues in the past few days with RPM not going over 2800, and cruise control locking on. I spoke to the Service manager today and he thinks the EGR valve is sticky and I cannot go over 2800RPM only does it when the car is very cold.
What I want to know, has anyone done the EGR blanking Mod to the V9X engine yet?
regards Matt

Probably not.
The EGR mod, mainly, is useful for keeping your intake clean. The other side benefits are just that, side benefits.
I've not noticed anything post egr mod with my vehicle, but I am happy I am keeping the intake side of things a little cleaner.
It's physchological ....

Same here, no real difference in umph noticed here. Only small thing I've noticed is that in hill starting on our driveway (got quite a slope on it) I don't need to,give it nearly as many revs to pull away. Used to stall at anything less than about 750-1000 with foot reasonably pressed. Now comfortably pulls away at around 750 with foot not nearly as close to the floor.

Ok, where I really noticed the difference was above idle. Around 1100 to 1500 RPM mark, Just on that intial progression of boost. Top end and idle felt the same. Fuel consumption did come down 9.5l per 100 down to 9. Was very happy about that.

Finally did mine , as said a bit better on take off however my car has only done 4000 klms. I look at it more for the preservation of the engine over time.

Hi all, i spoke to my mechanic about the EGR blocking when I had my 40k service. I asked what he thought, his reply was "don't wanna know you if you do it"
He said Nissan put the EGR on the engines after the 3.0TD in the earlier D22's were melting pistons. As for the soot going into the engine, the engines are meant to get periodical carbon cleaning done on services.
I know a lot of people have done it with no dramas, but they've obviously done it for good reason so I'm gonna leave mine on. In saying that, I average 8-8.5L/100km so I'm really not complaining about effeciency, but the getting rid of the bit of boost lag woudl definitely be nice!
