PUMA 2.2 EGR Blanking - Flogging a Dead Horse

I've read so much about 2.2 EGR blanking experiences my eyes hurt.

I've a MY2014 2.2 which is completely standard. I previously had a TD5 to which I fitted a EGR removal kit (pass-through pipe) and would like to remove the EGR as much as possible from the current 2.2 puma. Understand that this isn't really feasible without significant trickery, but am still in 2 minds as to whether blanking plates such as this one:

http://www.ebay.co.uk/itm/EGR-blanking-pla...xyeZNTUjpp

yield a decent job of 'removing' the EGR valve effect, WITHOUT triggering the EML. Can anyone offer an up-to-date experience or opinion on this?

If I did bite the bullet and fit one to find out for myself, what's the procedure for fixing the EML (if) it comes on.

To reset the EML you'll either need to plug in a diagnostic tool and clear the fault (which will last a few drive cycles before it comes on again)

Or you can remove the blanking plate and then it will clear its self after a few drive cycles.

Basically don't bother. If you want to get rid of the EGR, get a software patch from Bell Auto Services and then just blank it off fully. Will cost about £200 or if you get a remap it's included in the cost of the remap.

Is the EGR giving problems? If not just leave it till it does. Taking it out is not going to turn your 2.2 into 4.2 V8 ....just my opinion...

Its not so much a performance thing, more a durability concern.

I'd imagine even with a re-map the car won't pass emissions tests for MOTs? A problem I was hoping to get around with a semi-blanking-plate.

Mine is a 2.4 but I think the egr system is much the same on your 2.2. I had a problem with the egr ( 70mph to limp mode in lane 3 of the M6) did alot of research, found it needed to be disabled electronicaly. Pumping dirty air back into the engine cannot be good for it. More research led me to B.A.S. Bought the remote remap tool with an egr patch. All good so added a remap all very good transformed performance, smoothness, drivability to the extent that 3000 mile trips are not a problem. Passed MOT with remap in place and egr deleted. You can switch to original map at any time. Plus you get a fault code reader and reset with live readouts as good if not better than £100 - £200 stand alone readers which makes the BAS egr delete a bit of a bargain even if you don't add a remap

It won't make a jot of difference to the MOT as the MOT doesn't test for what the EGR valve is designed to do, which is reduce NOX. Darren

a 2.2 with a remap and the EGR set to closed will still pass the MOT just the same as one without.

There isn't actually an "emissions test" for Diesel MOT's in the same way there is a gas check for Petrol engines, it's a smoke test. The device they use simply measures the amount of soot in the exhaust gases, you might actually find the engine has a slightly reduced amount of soot in the exhaust with the EGR blanked off as the engine will be running more efficiently.

A faulty EGR wont cause an MOT failure, but the engine management light illuminated on the dash will.

Recirculation of exhausts brings down combustion-temperature and lowers oxygen. Made for reducing thermal NOx-Emissions.
You have to take a note of that when considering blanking the EGR without doing any mods to the map...

But I totally agree that getting rid of it is the best thing you could do!

2013 Defender 110 Puma 2.2 SW Alpine White

Hey guys, I have had a sticky EGR valve on my 2013 Puma. So one day I waited until I heard the chug chug sound when it supposed to self clean, unplugged it and sealed off the connectors with tape.

I have had no EML lights, no fault codes and zero issues with limp mode. I have noticed a puff of blackish smoke on startup but other than that... nothing. When I pluck up the courage I will remove the EGR all together and blank off the pipe.

I did this mainly because of the way the coolant runs through a cooler behind the head which the exhaust gasses pass through and significantly increases the temps on my Madman read out. I had the Defender remapped and installed a larger inter-cooler, yet my coolant temps would run around 100 deg.

After disconnecting the EGR I rarely go over 91 deg.

I just asked the BAS guys what options I had for my 12 reg 2.2 and they recommended a BAS2 RRC that comes in at Â£834

You're paying for the diagnostic tool (about Â£400 for an IID tool), the RRC tool is just a rebranded IID tool.

Then the remap its self is about Â£400, if you only bought an EGR delete then the delete is about Â£200 on its own.

Bear in mind you'll have a diagnostic tool to keep and use for diagnostic and configuration purposes. I sold my IID tool a couple of months ago (I've sold my Defender so didn't need it anymore), I got about Â£320 for the IID tool, so I didn't lose much on it.

If you don't need the remote tool then just get an EGR blank/remap. Plenty of options out there.

EGR

Many thanks, ZSD-PUMA!

That makes sense. Now all I have to do is decide whether to go for the remap or just ditch the EGR. I can see the benefits of scale.
Appreciate your input!

If you made the EGR removal only, the amount of oxygene would rise what caused a faulty ratio O2 / diesel.

As a result the combustion temperature would rise.

Consequently it would make sense, if you readjusted the amount of diesel in order to arrive at the right ratio.

But that's just my understanding of perfection. Nothing too important though.
