hi everyone just bought a 2011 autobiography and saw lots of threads regarding the egr best being removed or blanked but I can’t seem to find the kit to buy as only ever seems to be kits for the 3.6 are they the same? And in same location?

think you'll find that the 4.4 is best left well alone. EGR blanking will interfere with the engine settings/CPU and b*gger up your DPF regens (so I understand).

The 3.6 DID benefit from the EGR blank.

so are they easy to remove and clean?

Yes, the posts about issues and best removed or blanked generally relate to the 3.6. As above, best left alone on the 4.4 as affects things more.

so best to clean?

Yeah, they can still get gunged up. Not sure if there is a how to in the Wiki.

Not long ago I had a Quantum tuning remap including mapping out the EGR.

I then made a 2mm stainless blanking plate to physically block off the EGR.

My MPG has increased from 24mpg to 27mpg avg. I rarely do motorway miles and boot it past 3k rpm every journey at least once to wake the second turbo up. I'm fairly pleased!

Drivability and torque has definitely improved...just wish I could find a solution to mapping the ZF8 box!

I'll make my own plate when I get around to it, having had a very mild remap with EGR delete some time ago.
For those with a DPF who are concerned about the effect on re-gens, the EGR valve gets CLOSED during re-gens to ensure that the fuel-rich exhaust all goes to the catalytic converter so that it can produce the required heat to burn the soot in the DPF.
I consider that the EGR cooler is probably responsible for the demise of the oil cooler gaskets so preventing EGR should increase the life of those gaskets.

Yes to add, in the spirit of transparency (if those read my other recent posts) I've had DPF full issues recently but they have been unrelated to EGR blanking and since resolved. So don't let that put you off.

I'm currently floating around 3-4g soot and it regens passively quite nicely.

4,4 EGR is quite eternal part, almost never fault. There is nothing to clean, it just black inside like exhaust pipe, and you dont clean exhaust pipe, right?
Leave it alone.

If it ain’t broke, don’t fix it.

In the interest of providing a balanced set of replies here, you can indeed remove/blank the EGR system. You just won't find a kit to do it so need to make your own. 2mm steel plate is fine.

As it needs a remap to get it to run without EGR flow why go to the trouble to physically blank it as well? 2012 TDV8 Vogue (L322)

Pretty sure this has been covered before, but if mapped out it is to cover the possibility of a sticky valve surreptitiously leaking. Cam
