Following the help and advice from fullfatrr members, i thought I�d document this for anybody else who wants to give their Rangie the full air treatment. Mine is a 2005 L322 - later models may varie.
The Air filter is on the left hand side of the engine, running front to back. Mine was dirter than a weekend in Paris without the wife. Take this out, clean out the airbox, and drop in the new element. The element has a offset lug so only fits in one way. 
2) Breather This is a cheap little filter that needs to be changed to prevent damage to the turbo. Its located to the right of the air filter at the back of the engine below a sound proofing mat. You have to remove a plastic cover and two rubber gaskets. Undo the screws holding down the wiring loom, you should be able to unscrew the three screws holding the breather cover in place without disconnecting the loom. 
Replace the breather 
Inside the cover you will find the filter, replace the o-ring at the same time with the o-ring from the kit. Before replacing, change the gaskets supplied in the kit, these should still be in the retainers on the engine as below - 
You can now replace the left hand sound proofing and engine cowling. 3) EGR Blanking kit. The EGR recirculates exhaust gases to insure certain chemicals are burnt off before being expelled from the car. the use of this is questionable in a)diesels and b)countries with quality fuel. It appears more as a practice just to appease the Bill Oddie crowd, resulting in warmer (less dense) air, less o2 in the mix and crap being circulated in your engine. Various kits are available online to blank off this valve. The one i chose completely blocks the exhaust and allows the intercooler air through. Some kits also have place to terminate the control valve (this may cause an engine warning light to illuminate on models newer than an 05. The EGR valve is located at the front of the engine, you will see the (large) intake from the intercooler, the metal take off from the exhaust and a small control tube.
The EGR is held on to the head with four bolts. You will first have to remove all the piping. A word of warning that my valve was full of exhaust gunge which far from an elixir of health is probably quite harmful. Protective clothing might be wise. 
Removing the intercooler hose 
My valve was jammed with exhaust tar I cleaned out as much as I could being careful not to allow any gunk to get inside the engine (which could have been fairly fatal for it). 
This photo shows the EGR removed and the blanking kit ready to be fitted. Once the EGR was removed, i added a small amount of firegum to the blanking valve and attached the exhaust take off pipe. DO NOT GET THIS NEAR THE INLET. This is purley to help get a decent seal and not get any nasty gases in the engine bay, re-close the jubilee clip with retainer.
Carefully bolt on the blanking kit and re-attach the intercooler hose and jubilee clip.
You will now need to blank the control tube. I did this by inserting a screw down the tube 
Adding some heat shrink..
And cable tying out of the way..
Make sure everything is secure and re-attach all the cowling. Start and check all is well. Below is a photo of my MOST screen, i reset trip 1 on the way to my brothers to perform this operation, and trip 2 on the way back. Once i got home i took this photo.. 
One of the biggest changes is now I can hear the turbo spin down when take my foot off the throttle, a massive improvement. Hope this helps anybody thinking of making the mod. __________________ 2015 FFRR SDV8 2011 FFRR TDV8 4.4 - Gone 2005 FFRR TDV6 - Gone Last edited by DaveAngel on 4th Sep 2011 10:35am.

Thanks for the comments, good luck doing your own - there were a lot of people talking about adding a EGR blanking kit so i thought I�d give it the full treatment and write it up.

Replaced my EGR a couple of days ago, and although the pic is not the best you can see all the black sludge,nice!! 
Changed the air filter to a K&N, pleasantly surprised at the difference it made and early indications show an extra 2-3 mpg (from computer figure) not done the full tank test yet. Just the breather filter to do now, if I can ever retrieve the allen keys I dropped on the undertray lol  Last edited by zetjester on 25th Apr 2013 1:51pm. Edited 2 times in total |

Nothing conclusive as the wife has had the car for the last couple of weeks. She has no concept of driving economically... I did reset the mpg counter and then drove to work, and on to mams house. About 40 miles, over mixture of country roads and motorways and the displayed mpg was 33. There is certainly a lot cleaner pick up from the engine and a noticeable improvement in acceleration. |

The PCV/oil breather has a new system which is a kind of fit for life unit as it relies on some swirl system to filter the oil out so no filter of pressure thing to block or break, well worth doing IMO.
