Not sure I get the point here. With the puma 2.4 after switch off there should be those 5 chuka sounds, that is the normal EGR cleaning cycle.

Yes, but it should be an almost unoticable sound. You'd have to concentrate to hear it. If it loud, it's dying...

My EGR failed almost from new within the first 5000 km with the truck frequently going into limp mode and engine light on, but that had nothing to do with excessive sound. It was replaced by a new one, and in the next two years it was a relatively loud screeching sound each time on turn off, which I thought was normal, and actually it probably was. Then when the truck was 2 years old, I switched from cheap French supermarket diesel to BP Ultimate diesel, and I never looked back. Within two tanks of that stuff the chuka chuka cycle became an extremely gentle, but still audible sound. And that until today, now at 6 1/2 years. Maybe worth a try for you too (unless you already doing that).

I have said this several times in previous posts since I believe it to be the case, but usually have been shot down in flames by the "chukka chukka is normal" school! 
I believe that a correctly-functioning Puma EGR is almost silent in operation. When it starts making the chukka-chukka sound it is deteriorating, although it may work for years in this state. When it then stops making this noise, it has failed. |

How do you define which of the two is more audible: "almost silent in operation" versus "an extremely gentle, but still audible sound"? Not so easy comparison without having the trucks side by side, but I think we both are saying more or less the same thing using different words.
At least to compare light output in reliable numbers, we have the standardized measured, raw, effective, calculated lumen,.... or don't we? Looking for my hat now   You never actually own a Defender. You merely look after it for the next generation.

Just to confirm, my 2.4 goes chuka chuka chuka
I have also noticed all the transits we have in at work all make the same noise, Peugeots do depending on what engine is fitted. I thought its normal behaviour? Never heard one make any other noise other than that? When running a diagnostic test on them, they make the same noise, and it all shows up ok, and working on the screen. 80" 80" 86" 88" 90" Wanted, Forward Control Anything considered. |

You'll notice! If you are driving and it is audible over the engine, it's too loud.
When you turn off the engine and you cannot but hear it, it's too loud. If you turn off your engine without specifically listening for it and don't notice, it's ok, even if when you concentrate on it and then do hear it. It's quite a noticable difference. I came home this evening and forgot to listen for it and can't remember hearing it, so it's fine again. Before I could nit ignore the sound even if I wanted to. In fact, even it wasn't solved without any cost, I would've gotten it removed out of the ecu. Cost is the same as a replacement but it's a definate solution. |

Maybe you should post some pics of what they did, where they drilled the hole, etc., that could help others who'd like to give this a try? |

Only thing that worries me with this is how do they stop the metal swarf from going inside the EGR valve when drilling into it? 110 Hardtop

I'd be more worried if I couldn't hear the self-clean when switching off the engine.
You shouldn't hear it when the engine is running and it shouldn't be too loud on the self-clean, that's the sound of it sticking. However, it should certainly be noticeable when it self-cleans on shut down. Anybody who suggests it should be almost silent is incorrect. Any Ford derivative with this EGR makes a noticeable noise from new. When I swapped my EGR out for a new one, it made the same noticeable noise. I'm only saying this as a lot of people might read this thread and think they have an issue when they probably don't. I'd love to know what grease they are putting in that will withstand the amount of heat that goes through the EGR. I would of thought it would just burn.

Agreed, mine had *always* been audible from new when turning the engine off.
At some point in the past, I had unplugged the EGR and left it like that for a few thousands miles, but it clogged up, so that when I plugged it back again (for MOT or the like), it made an awful screeching sound that I could hear even when driving, mostly at gear change at low speed! That was not normal... even though the MIL never came up (and no error code was ever logged in the ECU, I checked with my Scanguage) But I did not replace the EGR, instead, I poured some 2SO in every fill-up and a few more thousands miles later, it's back to normal, I cannot hear it while driving, but I can when switching the engine off. And I reckon this is the normal behaviour for that EGR. |
