EGR blanking plate on a MY13 2.2 Puma?

Dunelandy is the guy that removed the gears, I think post #35 shows some pics. Reading the most recent threads, he still has no MIL light. This however is for the 2.4, not sure about the 2.2.

I've been following this closely for awhile now, as I don't have the money for a remap yet. At the moment I'm halfway through an experiment, which involves simply unplugging the EGR on shutdown and leaving it that way, once it's done the "chuka, chuka, chuka" clean cycle and is closed. So far in just under 3 weeks and 132 cycles no MIL light. Maybe I just got lucky, but it also seems to work for some of the members on the South African forum. I also have a spare EGR from the previous owner of my Puma, never did ask why he had a spare ! I've removed the gears, made sure it's closed and will try Dunelandy's idea after a month of running around with the current one unplugged. Plus it gives me a chance to pull the current one apart to check it's condition.

Oh yeah mine is also the 2.4, and the EGR was working fine before I unplugged it. Again like others have said, I just don't like the idea of pushing dirty exhaust gases back through the engine.

How are you getting on the egr in unplugged? No light still? I'm getting a newy in Feb and want to the same.

Sorry I never got around to following up on this one, but after 3 weeks or so of running around with no MIL, on the unplugged one, I changed the EGR for the spare, with the gears removed.
I should've just let it be!
After 3 cycles the engine light came on, I then put the original back on and left it plugged in. After 3 cycles the light went out, so i unplugged it. Don't know what I did, but after 3 cycles low and behold the light came on. Bugger!

It was an interesting experiment, with a lot of swearing and skin removed. You really do need baby arms to remove the EGR, without de-barking yourself.

In the end I jumped on the first group buy with Pete at BAS. Initially all I wanted was the EGR closed, but I went for the City tune as well, mine is the 2.4, still can't wipe the smile off my face every time I go for a drive.
After I flashed the ECU with the new map and closed the EGR, I then fitted a blanking plate.

The spare EGR was sold at mates rates to a friend, whose own valve was making the strangled chicken noises.

We've just had a massive problem with our EGR cooler - our 2012 defender (110) overheated and we kept loosing coolant. We had it towed to a land rover dealer to be fixed and we got the dreaded phone call 3 days later telling us that they had to strip the engine down to work out what the problem is- they said it was going to be very expensive, to the point that they would have to give me a quote and we would have to accept it before they proceeded. And that wouldn't guarantee that they'd find the problem.
Needless to say I refused and bought a trailer and towed it back 5 hours to get her home.
Our mate who is an awesome diesel mechanic deduced that it was an EGR problem and managed to pressure test the cooling system. He narrowed it down to the EGR then dismantled it from the vehicle. 4 years old and it had a bloody joke in the cooling system of the EGR!!!
Blanked it off completely and ..... no more problem. The engine fault light has come on but hopefully we can find someone to code it off.
And we didn't have to strip the engine down !!!!!! So much for land rover mechanics knowing their vehicles.

Its definitely not a bad idea to install an EGR blanking plate.


On vehicles with sensitive ECUs, you want to experiment with a 7mm hole in the blanking plate to allow some gas flow. This is common in other makes and make a massive difference to limiting sludge build-up.


Another route around this sludge build-up is a oil catch-can. It would be very hard for a dealership to void a warranty claim with this setup but no doubt they would try.


Any of this stuff though can be removed before you send the vehicle in for service.

Pete @ BAS has advised me to remove the banking plate as it helps with temp control etc. That said my egr is electronically turned off and I have a 170AB tune with BAS intercooler. Needless to say I am very with the transition and control I have with BAS.

Note: I originally had a D-CAT(kept) + Blanking (removed) + Alive tune(BD)> BAS

Doesn't having a hole in the blanking plate for gas flow mean the engine light doesn't come on - or is that wrong?

I dont understand how the egr can be switched off yet help cool the intake temps?

Also egr gas have been proven to increase intake temps from what i have researched. The higher intake temps help lean out the a/f ratio hence producing lower emitions. Someone please correct me if this is incorrect.

Apparently the logic on the 2.2 is different to the 2.4, it still did the cugga chugga after shutdown with or without plate with either tune. Anyways this is done for better temp regulation and best explained by Peter from BAS. I removed the plate per his guidance.

So i contacted BAS and asked why it is a good idea on the 2.2s to not blank the egr. The answer is becuase if i ever want to revert it back to standard then its a good idea for the egr to continue its cleaning cycle.

Im keeping it blanked.

On a separate note i will be travelling to Adelaide from sydney for Christmas with the family. I will be reporting air temps, pre turbo egts with the Alive tune. Will post my results once back, im really keen to see what sort of egts my 2.2 will be running and it would be great to see how they compare to other people's.

Who did you speak with? I was explicitly asked to remove it. Anyways I am happy either way and very happy with the new smooth tune.

How are you monitoring egt?

cheers
