How difficult is to replace it? I am quite good with DIY but i have very little experience with engines. The mechanic quoted some 250 pounds for parts and labour...

Personally I myself bought a Diagnostic tool and Torque wrench as I didn't have either and did it myself saving 150 if I remember correctly. I also bought from Neil @ Shukers parts as he gave me the best price on the market. If you'd like his E-mail please contact me via PM. Diesel$ Live$ Matter. ⛽️🛢️👨🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧

I have stuck my head under the bonnet to take a look at where the valve is... sure there is an awful lot of stuff between me and the EGR valve bolts. Do i have to remove some parts to access it or is it possible to take the thing apart directly?

I removed nothing except for moving the axle breathers out of the way. That's the part that's difficult about changing the EGR it's the access to the bolts. there are four in total. One of the lower bolts is best acessed from underneath. But as I said it is a pain. Diesel$ Live$ Matter. ⛽️🛢️👨🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧

Oh forgot to mention. You will of course have to remove the EGR electrical plug as I mentioned before. Other than that and moving the axle breathers away that's about it. Diesel$ Live$ Matter. ⛽️🛢️👨🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧

Like Charlie says - it looks quite daunting

Perseverance  Oh and determination. It helps with getting the old one off to think how much the **** cost you by packing up and forcing you to buy a new one in the first place..   Diesel$ Live$ Matter. ⛽️🛢️👨🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧 |

Thanks Pete,
If you and bell-auto-services ever come up with a way of illiminating the whole system i would certainly be a customer. The whole design concept of the EGR on the Puma engine is  (compared to none at all or the simple blankable system on the TD5 particularly for us non-european drivers).
I live in the middle east where the truck runs on low sulphur diesel as opposed to ultra low that you have in europe (many many times more sulphur). As a consequence the oil ,turbo, valves and crankcase are full of soot. No doubt the EGR valve is too (mine sticks open and shut too with all the usual fault codes). Furthermore i operate the truck in temperatures above 50 degrees celsius at times and cooling is a big issue. Its nonsence that the bloody EGR dumps heat into the already struggling cooling system through its cooler. I would love to be able to remove the valve and cooler, bypass or blank them off neatly and reprogram the ECU to ignore the bloody EGR electrical connector input. As an aside: Perhaps just regular cleaning of the EGR as opposed to buying a new one would keep it sticking? Happy trails Guys. |

You do have 3 possibilities (in order of cost):
1) Unplug the EGR valve and ignore the orange light (or clear it every 3 cycles with an OBD tool) 2) Fit a blanking plate with the correct sized hole so most of the exhaust gasses are stopped but the MIL doesn't go on 3) Get a remap from e.g. Pete with the EGR switched off (do this whilst the valve still closes...) 4) Get your own supply of better fuel.

Changed mine this weekend. Like many have said, not a technically demanding task (its only 4 bolts), but it is fiddly and time consuming, and I speak as a Sea King helicopter engineer. The most frustrating thing was dropping the bolts (often) and ten scrabbling around under the Landy to find them.
Perseverance and patience is the key! Nick |
