This is a picture of the new EGR valve - a bit jumbled because of all the pipes nearby.
It shows a hole about 19mm diameter from the top that I am not sure was there on the old one. Maybe someone can snap a pic of the older type (2007 model)

James, you can come check on mine when you're around GB

Maybe it is a fresh air intake, to allow people to blank off the EGR without the MIL coming on?

I had my EGR replaced recently too - just checked mine - it's the same as Cape Landy's one in his photos - with the hole. I'm keen to find out if this is indeed a new modified part, because my LR dealer said they were the same - not that they aren't usually wrong! I can't remember what the old one looked like either.

On the good news front - my Puma has been trouble free for several months now, which, if anyone recalls my earlier posts - is very good news. I'm enjoying it now.

Mine's also been very good.
I saw on my printout that they did also another software update at the time of my EGR valve.
That might also explain while there was such a difference when she came back.

Now I am scraping together all the overtime I can to afford the extended warenty although the exclusions are a bit scary considering it's a puma.

Well - my new EGR took all of a few months to again raise it's ugly head - engine surges on/off throttle. Still waiting to discover the best blanking solution - we have 3 it seems, Robofarmer, Bell and the German fellow. I can't believe these EGR valves are so prone to causing issues.

Add to this - oil weeping from new transfer case flange seal.

Is it the LR mechanics - or these vehicles? The unfortunate pattern of getting at the most 8 weeks without failure is alive and well.

Not sure if it is the EGR

At low revs, cold to warmish engine T I can hear like and irregular noise from the inyection rail. I can barely see the revs going up and down. Could the EGR valve the source of the problem? Also I noticed like a lack of power up to 2500 revs of so.

Any feedback is appreciated

Yes, that is the symptom mine had - sounded a bit like a cricket with a silencer chirping near the fuel rail and revs were a little eratic and mostly ony when cold - gets much worse over a few weeks so that when you shut down the engine when cold it sounds like loose spanners clanging about
