How to assemble the electronic part of an EGR valve (Peugeot/Citroen 1.6HDi)

Is your EGR valve stuck! The spring at the top electronic part could be broken! This is how to take it apart and put it back together.
This is in a response to a comment of how to assemble the electronic (top) part of an EGR valve for a Peugeot/Citroen 1.6HDi engines, probably will work for Volvo, Ford, Mini, Suzuki and Mazda 3.
Do not open the top part if you do not need to, it may not be exactly the same as mine!
A more updated video showing taking apart the EGR valve and cleaning everything is here: • The complete guide to ...
The electronic (top) part on the newer version has a slightly different design.

This was really helpful to me i messed around with it and i was able to make it work again thx to you video i want to say thank you man...

[@moremolecules]

Hi Amine, I am glad it has helped :-)

[@peterc2208]

Another excellent video. Telling us what not to do is just as important as telling us what we can do. I learnt what not to do the hard way, as always. Dare say my egr would be working now if I knew the correct way to put it back together. I did get it back together, just never sure it was right. Also good you showed us how much tension there was on that spring. Many thanks, much appreciated.

[@josefethan5905]

love this vedio i have searched for 2 days for this kind of vedio, i did this then i didn't know how to put it back but now i understand i did wrong. thank you bro.

Removing the EGR cooler is no joke. Spent a small fortune buying specialized tools. In retro, would have been better to take it to a mech and see if the mech will remove for- clean it yourself, and have mech put it back together to save $/time. Good vid, brother.

Really great video buddy. My connectors were covered in soot. So cleaned that as well. Your English is absolutely brilliant BTW 👍👍👍 I've realised I haven't put mine back together properly. I have a mini R56 and it seems a little different than this unless I haven't taken it apart properly. I thought they were the same egr valve. I'll have another look. Thanks very much my friend

Hi again... yesterday I finally took apart the EGR valve. Well, first of all I did it three years ago while the car (Peugeot 207 1.6 hdi 90 hp) was 267.000 kms, at that time I cleaned the mecanical part of rhe EGR and I changed the electrical part because it was stuck. I had the chance and swaped the elctrical part from a second hand citroen c2 1.4 hdi which fit perfect despite of having a diferent reference. The mecanical part seems to be the same in both models but it is not, only the electrical is the same. Yesterday I took it apart again 67.000 kms after, because the fault code P1461 was showing up in the Lexia regarding to the electrical part of the EGR intermitent stucking. I also have to say that the car runed fine and no engine light was on in the dash. Once I opened the EGR I saw not so much black powder ( carbon) and after cleaining it up again, the electrical part keept getting kind of stuck not retorning as it should. Thanks to your video I opened and blow some dust out and reinstalled as you show as (thanks for that!) but it improved just a little bit 😞. So I decided finally to purchase a completly new EGR. I think I will get the Valeo one, after all it worked fine 267.000 kms the first time 😀😃. Thanks mate!

[@moremolecules]

Thank you Marcus for the good words and story write up. Unfortunately, you may have to replace it. Eventually it comes to a point where one needs to replace the EGR. I have not tried Valleo as it was too expensive or I could not find Valleo. When I was replacing mine, I bought Haas and that one was not machined properly and was sticking as brand new. The channel inside where the pin rotates was not smooth enough and was purely sticking from the mechanical rotation. I then searched quite a bit for a good EGR and Hella are OEM manufacturer for quite a few companies. I bought their Peugeot/Citroen EGR and have not had problems with it for the past 2-3 years now. If you cannot find a Valleo one and/or it is too expensive see I would not shy away from Hella. You also need to recalibrate the new EGR with Diagbox/PP2000. All the best and good luck. 267k km is pretty decent.

[@bestione761]

@@moremolecules I bought the Valeo one.. 145€.... I will do the recalibration ( "aprendizaje" translated from the lexia in spanisch "learning") puting the contact on and off after some seconds am I right?

[@moremolecules]

​@@bestione761 145eur is pretty good price. I bought my Hella for ~£130, so about the same price. Yes, in my english version is called Electric EGR valve replacement, but it is commonly refered to as recalibration. Have a look here: kzbin.info/www/bejne/ZqSWaqecntmiqdE

[@JoeBob79569]

I took mine apart last week, as it was jamming, even after a good clean. The inside of mine was slightly different even though it was on a 1.6hdi. Peugeot 407 2006. There were two plastic parts: a cover and an inside bit that rotates (on this one it seems that the cover rotates). The inside bit on mine (that rotates) was missing a few bit of plastic that hold it in place, and the spring was all jammed up behind it and bent out of shape. I'm pretty certain that the previous owner (previous owners do some weird shit!) had taken it apart and botched it when he put it back together. There was even a screw missing from the outside. I just blanked the EGR instead, as the car was pretty much undrivable, and I took out the spring and plastic bits. My hope was that the EGR would think that it's able to rotate freely, but I'm still getting errors on the dashboard. Probably some kind of feedback resistance or something. Maybe I just have to clear the errors, or maybe they'll go away after a while. Else I'll just reflash the ecu. Or maybe try some delicate plastic welding on it if I'm feeling adventurous..

[@moremolecules]

Hi Joe, I agree, previous owners do some weird stuff. Sometimes, depending on the model, the ECU will throw an error if the EGR is blocked and the error will be persistent. See if you can clear the error codes, but it will most likely reappear.

[@JoeBob79569]

@@moremolecules Yea, it reappeared alright. Two of them. And it's now in limp mode too! I think I'll have another go at fixing the spring and the plastic bits, and failing that I'll just reflash the ECU with the EGR warnings turned off. Think I'll still keep it blanked off though..

[@moremolecules]

@@JoeBob79569 Not too sure that the limp mode will disappear with the EGR blocked, even if you have fixed the spring/plastic bits. I have not seen it done, but if nothing works and you want to keep the EGR blocked, you can try to re-learn the EGR with diagbox/PP2000. As if it is a replacement EGR valve.

[@snoucibenderrah1835]

شكراً على هذا الشرح المفصل.

[@DavidGarcia-kf9wo]

Good video, mine was little block, some friction, and no free spring back. So I wonder it is broken. Only... mine has 5 pins connector, is that the same? It seems to have only two... Thanks.

[@moremolecules]

Not too sure, what model/year is you car? Do you have any problems with the car actually?

[@Enes-ji5nr]

Hi, firstly thx for your video. I've removed the EGR valve for cleaning and reinstalled it but the engine is not starting now. It was starting before removing egr valve. it would be great if you have any ideas. Ford Focus 2010 1.6 TDCi

[@moremolecules]

Did you remove the fuel filter? If yes, and you have the bulb-type thing, you need to pump it until really hard, say 20-30 times to purge air from the fuel system

[@moremolecules]

I have posted a new (i.e. updated) video that covers pretty much everything to do with cleaning/dismantling the EGR valve in 1.6HDi/TDCi engines. You can view it here: kzbin.info/www/bejne/rYW0pYmAetZ6jqs

Hi cantOdoObetter! Have you ever taken apart the solenoid part of the electronic part and know how to do it? I have seen two of these egrs failing due to jamming in that, but I don't know how to fix them or dismantle. .

[@moremolecules]

I have not taken it apart, but are you certain that it is the fault of the solenoid?

[@supernova5354]

cantOdoObetter, yes. It is so jammed the spring in the electronic part can not operate/reverse it.

[@moremolecules]

I will try to see if I can open my spare EGR valve. I will let you know if I have made any progress, but cannot promise anything.

[@bongdan]

@@supernova5354 hey bro, have same issue the thing which rotate is stuck and rotate very hard, the spring cannot reverse it. How do i clean that i tried everything? How do i open it? Couldn't open it

[@abdelghaniabbaoui222]

شكرا لك

[@milek021]

Any way how to check or to be sure that electronic part/solenoid is OK or maybe faulty ? Taking the EGR from 1.6 tdci/hdi is quite of job for NON mechanic folks so I simply want to be sure, if possible, that after cleaning the valve also electronics is fine to put back! Thanks...

[@moremolecules]

The easiest way is to connect to diagnostic software (PP2000/Lexia for HDi) and check if it is operational, e.g. mechanical and electronic part. Also, with the said software you can monitor the valve position and percent opening during engine operation. This should be a sure way to check performance

[@milek021]

Should PP2000/lexia work with Ford CAN network ?! I mean I know that 1.6tdci in my Focus mk2.5 is actually PSA hdi engine but have no idea will PSA software would be able to access to EGR trough ford obd2 CAN network, either HS or MS :(

[@moremolecules]

Sorry, I did not realise that you were asking for a Ford EGR. I do not think the PP2000/lexia will work with Ford and I am not too sure which software can be used with Ford.

[@emy7990]

I just removed the EGR valve, is not that bad inside of it, just black smoke, but I can not remove, not the electronic top part, but the one that connects with the EGR body, you shown in the other video. I removed the three bolts and when I twist it is holding something, I think the valve is closed, must be opened, how? Thanks

[@moremolecules]

The piston valve is kind of independent of the top part (not the very top electronic). Twisting should separate it, I think counterclockwise. Try to wiggle it out, there might be some carbon build up that is holding it, but that would be quite surprising. Do you mean the valve or the middle part is closed and not opened. The valve will be operated electronically to close/open whenever needed by the ECU

[@emy7990]

The middle plastic part, I just presume that could be close something inside....I am afraid to put much pressure on it do not damage something..

[@emy7990]

Done. Thank you very much. I twisted it a few times with more pressure and broke the carbon, also a seal came off....Now I need cleaning it. I have all the stuff for cleaning it. I was nearly to mount it back, but lucky that you answered so quick. Thanks again....

[@moremolecules]

I assume you have the 1.6HDi or an EGR valve is the same/similar? There is not anything inside that holds it, only the three bolts hold the plastic part. Even simple lift without twisting should release it.

[@moremolecules]

No worries and well done. You have to be careful with the positioning of the seal when putting it back, it sometimes twists and it has to be flush with no twists.

[@josefethan5905]

i am subcribing u know bcs of this vedio

[@moremolecules]

Thank you! I generally put videos that I have not found on youtube and put them so other people can benefit.

[@josefethan5905]

i have one question, what wich materials we can clean it, can we wash it with petrol or just with spray cleaner.

[@moremolecules]

I would not wash/clean the electrical bits and pieces, but for the carbon build up I normally use EGR cleaner or some sort of carb cleaner. Most auto stores will have carb cleaner. Not too sure if it can be cleaned with petrol, I doubt it.

[@josefethan5905]

thanks for quick response, can u give me one sugestion, if i clean it with spray cleaner this will work or i buy new one, if i buy from internet too much diffrent prices from 100 - 350 dollors, i don't know wich one is better if u have any idea pleas share with me.

[@moremolecules]

Depends on what is wrong with the EGR valve. If it is just hydrocarbon build up, then cleaning will work. It is worth trying cleaning it due to the cost of purchasing another one. I previously bought a HAAS EGR valve and this thing broke within 8 months. This is the spare in the video. I think there was some sort of manufacturer fault, as the pin was catching in the groove. I could have filed it, but could not be bothered. Bought a HELLA EGR valve and that has been great, no problems at all. It seems that the HELLA is a preferred choice for a lot of manufacturers. If possible I would buy HELLA EGR valve. Yes, price varies quite a bit. I think I bought mine for 130 (GBP). Good luck!

شكرا جزيلا

[@nagymesterb4945]

thx

[@bongdan]

Bro how do you open the rotating part? Mine is stuck need to open it and dont know how

[@moremolecules]

Hi Bongdan, there are two types of the same EGR valve, one in the video where the rotating part can be opened and another one where it cannot. If you cannot open the rotating part it means it is most likely the second model. You do not need to take it apart, just hold the whole part and fit it together. Hope this helps.

[@bongdan]

@@moremolecules thanks for replying. my issue is that the rotating part from the electronic part is rotating very hard and slow and the spring doesn't have enough power to rotate it at all...i wanted to open it and clean it but cannot see how

[@moremolecules]

@@bongdan It could well be the second type EGR valve, for that one the rotating part cannot be separated, or at least I do not know how. There is something going on if it is that hard to rotate, it should be very easy to rotate. I assume you have already separated it from the bottom part. Inside is the electric motor that moves it, it could be that it is completely broken inside.

[@bongdan]

@@moremolecules yes i separated all, the electric motor is spinning very hard, the spring has no power on it....I'm affraid I have to buy new EGR they dont sell just the electric motor

[@moremolecules]

@@bongdan Unfortunately no, they do not sell individual parts for the EGR.

[@pcsoundrecording347]

this is different to mine in citroen c4 1.6hdi 2005, no spring or anything falling apart like shown in this video.

[@moremolecules]

The one shown in the video is Peugeot Partner 1.6hdi 2007, so in theory should be the same. So, there are other designs of this EGR valve, thanks for pointing this.

[@whaatspot8615]

That plastic part 1:36 is not removable in mine one... Cannot lift it at all.

[@moremolecules]

As far as I remember it is metal, rather than plastic. It could be different type of EGR valve. It would be quite difficult to assemble it together without removing this bit, as it will not be visible.
