I did mine on my 2013 2.2 with aircon as it had exactly the same symptoms and DTC.
A member on here sent me some great instructions via pm and then I expanded them when I provided some instructions to another member via pm. I will look for them and send. I keep meaning to do a write up and post but just have not had time. First thing to note is the egr is made by pierburg for Ford, who in turn sell to Lr who rebox and add a lot to the price. You can buy the pierburg valve direct, when you do you will notice they have ground off the Fomoco casting 
If you look at the side of the valve you can see the pierburg part number, take a pic with a phone so you can expand. Check with GSF that you are getting a gen pierburg, you won’t want to do again in a hurry. You need to check your valve as it may be a different version, but these were the pierburg numbers that were correct for mine - 7.03784.00.0, 7.03784.05.0, 7.03784.09.0, 7.03784.10.0, 7.03784.18.0, 7.03784.20.0, 7.03784.34.0 |

Many thanks for that. Not looking forward to it. Not stuck my head under the bonnet yet but I understand it’s right at the back making it an even bigger pig to lean over and get to.
To put the job off even more I watched a YouTube video of people curing and EGR problem with a can of spray shot into the turbo. They claimed it worked but the hundreds of comments underneath called it b0ll0x. Sane me would agree, but when you know you’re in for a world of pain you want it to be true. Kind of like a faith healer preying on the sick 🤒 😆 |

I wimped out of doing mine on my 2.2 TDCi for exactly these reasons, and enlisted the help of a local Landy specialist who told me afterwards that it really tested him and that he got to use spanner and socket extensions that he otherwise hardly ever needs!
But TBH it felt like a waste of the part and 4 hours labour. If I ever see that error code again, I will blank off the EGR and enjoy a remapped driving experience which I feel is a much better use of probably less money  2011 2.4 White 110 CSW LHD

I have spoken to ian at IRB about mapping and EGR blanking. He recons it’s not a good idea on the 2.2tdci. Something about DPF and that burning off at a certain temp and the EGR and sensor having a hissy fit….. I didn’t understand, but I did get that the 2.2 isn’t a good candidate for EGR blanking

Interesting, Gareth at Empire Tuning was up for doing mine.... 2011 2.4 White 110 CSW LHD

Good speaking to you earlier.... My view - and some people might disagree - but this is my opinion. EGR is used as a control structure when a regen fails and shouldn't be blanked. But you can reduce it's activity outside of a regen. In simple terms, when the ECU strategy decides conditions are correct for an Active Regen, the turbo goes to a fixed angle and EGR is closed. Fuelling is then adjusted to increase the Exhaust Gas Temp/DPf temp - which ramps up to allow a controlled burn to take place. The reason you get a fixed turbo angle and EGR closed to increase efficiency and control to maintain a suitable temperature and flow to allow the DPF to burn off its soot deposits. However, if you now suddenly have to slow down (due to traffic on the motorway for example), the ECU software cancels the Active Regen and now wants to bring the EGT (Exhaust Gas Temp)/DPf Temperature back down as quickly as possible - to do this, the turbo becomes fully active and EGR is increased to reduce the burn efficiency and fuelling is backed off. Whilst it is true that temperature would come back down without the use of EGR (dirty air), its all about bringing it down quickly especially if the vehicle comes to a stop. So there is nothing wrong in software adjusting EGR opening in none regen conditions (and this can be set to zero) - as this just affects the NOx output and can be better for driveability, I would always leave EGR in place when a DPF is present as a safety back up. In a none regen condition, EGR will be closed full throttle acceleration etc anyway and all you would do is tweak the zero percent open over a larger window. But leave the regen section standard. So... I wouldn't blank if it was my own vehicle. RoW 2.2 (and none DPF) and 2.4 Tdci is a different matter.....

Fascinating Porny, and the reason this is such a useful forum
Let's hope my replacement EGR valve has a longer lifespan than the original  2011 2.4 White 110 CSW LHD

Didn’t realise @Porny and Ian were one and the same. Perhaps this is the time to show my wimp status and say I’ve chickened out to leave the job to someone who knows what they’re doing…… IRB 😉
Plus, to lessen the blow of spending on a boring EGR valve, a little remap might help 😆 |

Great explanation Ian (Porny / IRB) and makes perfect sense. I was aware that you could not do an effective EGR delete on a 2.2 due to its interactions with the DPF but did not know the details. Many thanks for providing them.
As you infer the only realistic EGR deletion on a 2.2 is to also delete the DPF and run a RoW std or enhanced MAP, which would break the rules for road use in the UK....if it were discovered 
Trouble is currently the MoT has it as a visual check for a DPF and EGR If I recall correctly, however I don’t expect it will be long before it’s a diagnostic check.but then again those sort of rule changes take years and as more vehicles become electric and diesels reduce they may not bother. Back on the EGR replacement, it is a real scream at the moon experience, not technically difficult, just so hard to get at the studs, nuts and bolts, the lower 2 , one on inlet and one on outlet you get at from under the vehicle. Using a deep 1/4 inch socket a UJ and a few extension bars. If on a hoist it would be a lot easier . |

If helpful…. My 2015 puma 2.2 Egr failed after 34000 miles. I purchased a new one of the correct spec and fitted it myself. On a 2.2 it’s a pig of a job and I ended up using a whole manner of unusual tool adaptions. My advice is get the correct parts and fit it. It was designed to work that way in terms of the engine efficiency etc. the old valve had totally seized and no amount of spray would have fixed it.

Thought I’d post just to close this off….. Ian at IRB had my Landy in and replaced the EGR valve - he also noticed the EGR cooler was leaking causing a lovely sooty black slurry. Replaced this too. All seems well and good - got a trip to Wales booked on Wednesday so looking forward to having it back in action.
Cracking service from Ian - nice to have a defender expert local. Ps. Also had a little remap done….. couldn’t help myself. Looking forward to some of the Welsh mountain hills where before I had to change down gear. Let’s hope it pulls like a train. |
