I have a car in the fleet that has had its egr and cat removed emissions are lower than spec on the door that's been mapped. The egr has a pressure sensor built in on some cars so when you blank it it no longer senses gas flow so it chucks its dummy out the pram. Hope it helps you further
If a Euro 4 HDi 2.0 (136 bhp) has been remapped to 168 bhp (stage 1), does the EGR blanking plate now need to have a hole in it? Thank you for this great video 👌👍
Excellent well explained video , best one on this subject that I have seen. I have a 2006 / 2.0 hdi so I am assuming this is a Europe 4 and so I can use a fully blanked off plate. Thanks for video as I say best one I have seen.
Hi mate the actual egr in 2. 0 Cdti is doing exactly same function. The Cdti engine is different and auxilirities around it is placed in a different location form 2.0hdi but once you find Egr you will able to see hot and cold side as there will be egr, egr cooler and 1 way in and one way out of egr. Principal is same and people blank them same way. Mind you some cars will like it some might start to run even worse.
Hi mate so basicly this is how it is. If you blank just a Egr end then just euro 4 emissions with no hole in a plate makes a gasses stay in a pipe it doesnt go through, that means more gasses going out from exhaust manifold as non recirculate. In euro 5 emission cars you leave a small hole in a plate some some gasses recirculates but not as much. This plating egr thing its a temporary solution to fix a stuck egr until you get new one as stuck egr prevents car from starting and it gives eml. If you want to delete egr you should map it out and block both sides or remove a whole thing and block and thats illegal in UK. I hope I answer your question. I do know some people who plate a only egr side and drive for long time like that but theyr egr cooler must be full of shit as it doesn't recirculates but it's only bad if you planning on removing plate in a future.
@@Mad4FrenchCars thx mate for info. But one more question. If the gasses stays in the pipe, is there any chance to blow up that pipe eventually, Cuz of compresion?
@@anubisanubis9859 no I don't think so mate it's not gonna be enough compression to blow it up I had a plate installed for a quite a long time and drove it like maniac and never had a issue
Sinspeed (UK) claim that simply blanking of the EGR will eventually cause problems (see below). Can you comment on this please? "Why does blanking the Peugeot 307 HDI EGR Valve system cause these negative effects? If the EGR valve is blanked off, then no exhaust gasses will recirculate back to the intake manifold and into the engine. - However, the engine ECU does not know that you have blanked off the EGR Valve, so when the Engine ECU calculates how much diesel to inject on each cycle, it will be doing so with the EGR flow included in it’s calculations. In order to properly remove the EGR valve and stop it recirculating exhaust gasses without the negative effects as described above, you will need to have the engine ECU remapped accordingly to tell the ECU that the EGR valve is to remain shut at all times. The engine ECU will then re-calculate the injection cycle to compensate for the EGR valve being closed and thus you will experience true benefits of having the EGR valve removed."
So the Sinspeed (UK) text you quoted is 100 % correct and if you look at some of my previous comments then you will see that I have already answered this question for some people. I simply show a way for you to blank egr. Egr blank is a temporary solution in a case of a Egr failure used by AA, RAC and other road assistants. As failed and open egr prevents engine from starting sometimes people even put some of the aluminium side from the fizzy drink can just to close a hole to get someone home. Permament solution is a whole assembly removal or atleast both sides of egr assembly blanked and Ecu remapped so that the ecu wouldn't thing egr is still there. As a temporary solution it can be used for a quite long time but it's still just a temporary solution. So if you want to get rid off it for good it has to be blanked from both sides properly and mapped out.
Also there is 2 types of people who wants egr blanked. 1st its a people who wants to clean engine from recirculating exhaust gas. These people should get it done properly that means both sides blanked and remapped so you would have a nice nice clean system. 2nd kind is a people who is trying to achieve more responsive acceleration and who blank egr and do not remmap so they get a richer fuel / air mixture, quicker response time on a acceleration and more power as ecu thinks more air is going in a mix but it isn't. I personally thing its nothing wrong with well working egr.
Today I noticed the solenoid connecting to EGR had snapped at the base of the vac hose anyway. Taped it up and blocked the vac line egr actuation so hopefully it doesn't muck up inside. No codes yet from blocking that. Will put plate in next 🤞
I have a 2008 308 2.0 HDi with the DW10BTED4. I believe this is a Euro 4. Does this mean I can simply apply a full blanking plate without upsetting the engine management?
Hi mate I had 2.0hdi 407 from 2005 which was euro 4 and had a dpf and egr blanked and had never had a dpf blocked. I blanked Egr in this video on 2010 407 2.0hdi and yes it has dpf and it doesn't block dpf. Dpf regen itself and burn a suit.
just read you saying" if blanked egr only the cooler must be full of shit over time ,but that does not matter unless you change or clean the egr valve .".I owe you a drink!!
Hi mate there is a noticeable difference in a low revs it feels more nippy then without any plate at all I guess that's becouse you still let some exhaust gas back to the chember but not as many so it either runs richer or gets more fresh air.
Ya 100% mate but we live in a planet full of green eggheads who think producing a car wich is polluting its own engine is somehow better then having a proper running engine
The chemicals have to use to clean 4 aerosols all cfcs caustic soda all helps environmentally and destroys engine sooner so ends up scrap si have to buy another plastic pig
I have a Mondeo mk4 Euro 4 engine, blanked the egr about 3 years ago with no problems until now. Im getting elm light and code is saying egr is stuck open🤔 is that possible if the egr is blanked off?
Yes mate blanked Egr is only as good as long it still works. If electrical bit gets busted it throw a fault as it's still connected to the ecu. Either need to remove and remap the car or replace with a good egr. Had someone with exact same problem before replacing Egr cure it.
absolutely first class presentation .. My 2008 2L HDI Citroen C5 has low performance . I have cleaned and then replaced the MAF sensor . Tested the air pressure 14 lb sq inch . from the air filter to the intercooler outlet tube. There is a small ish leak . but I am systematically checking for where the leak is. The pressure builds quite quickly then suddenly drops ,possibly indicating a split rubber hose opening up under boost pressure . Wish me luck I am a 78 year old tinkerer .mechanic . next step is to raise the car / remove the engine undertray and spray some bubble liquid around .interestingly your engine cover shows 1.6 HDI yet the video is showing a 2 litre HDI exactly like mine .The local garage owner did a scan and diagnosed low turbo boost .. no warning lights just no meaningful acceleration nor pulling power .
I just unplugged the egr electric plug and it disables the EGR. By the way i also removed the vaccume to the butterly valve since i thought it may try to block the air intake to allow the egr to work. did you leave the inlet butterfly valve plugged?
Well if you have dpf delete then same people who done dpf delete should have advised you of a best way to delete egr and how to keep it looking road legal
Has anyone else had their egr cooler leak coolant on one of these engines? I've got a coolant leak coming form the rear side of the engine and I think it's the egr cooler
Hi mate the flow goes from the back of the engine, through egr cooler then egr and then through metal pipe back to the inlet manifold so you need to blank it same place like I did it between egr and metal pipe going back to the inlet manifold. If you have egr delete on a ecu with remap then you would be blanking both sides so right next to intake manifold ideally and also on the exhaust side before egr cooler or in some cases then is egr deleted and mapped out you would also remove the whole egr housing but it requires proper blanking and also bare in mind it would fail mot as any alteration like that would be illegal. As its illegal to tamper with anything that deals with lowering cars emissions in UK.
Becouse my car is euro 5 emissions as its 2010 model and if I use a totally blank plate I will get EML. I explain in a video. Euro 4 emission cars use one with no hole in it at all. Euro 5 emission cars you reduce a volume of emissions going back to the engine but you can't blank it off 100% without getting a remap egr delete.
I have mentioned that egr blanking is only temporary solution. If you look for permament solution then all egr assembly should be removed and remapped or a new egr instead of a faulty one
Hello. I would have a few questions for you regarding the egr valve plate for the volvo c 30. ..2.0 ..d..100kw engine. .On my engine, the egr is turned off by software, but it is not blocked as you explain..is it also necessary to block the egr in my case... I hope you understand me. my English is not very good 😊..I would order the product if it is delivered to Croatia...thanks.
I have problem with rough engine working after some seconds, but when i put out little vacuum pippe on top valve on right side near throttle body its ok. i drive with pipe out n blocked with screw. what can be.. some electro vacuum valve or maybe need to work like that 15min and will be ok after
I would start from connecting everything back up and scanning a car with diagbox to see what fault codes you have. There is 2 vaccum selenoids on a 2.0hdi one is in a front and one in a back of the engine and either one can be a problem it's quite common.
@@Mad4FrenchCars it posible, on diagnos dont show it. (Sometimes says turbo presure sensor) Well pipe what i disconect is near down of the oil puting place. (Maybe valve, maybe trothle body air close not work, or some vacuum pipe cracked)
@@100janosky_3 it's always good idea to check vaccum pipes as it can be damaged somethere. If vaccum pipes are good then I would replace a vaccum selenoid it's only like 20£ from ebay.
that is teh butterfly valve throttle body. When egr is functioning it closes to block fresh inlet of air to allow more exhaust to flow to the inlet through egr. If you blanking egr you should remove the vaccume to butterfly valve so it doesnt block fresh air
@@aneeshzutshi3419 i block egr with metal plate.. put vacum pipe on but somehow again not work ok after 5km. So i stuck butterfly at 30% open n drive like that. Its better now + egr blanket (closed) n from 7.8l get to 6.4liters. But maybe turbo not works good allways dont know. When i find good mehanic it tell me what to change..maybe vacum valve..maybe trottle body.. etc. 🙂
Hi mate the only thing which helps is phisicly taking a Egr and egr cooler out and cleaning properly. 2008 is a cross model between euro 4 and euro 5 I would probably go with blank with no hole as I think it will be euro 4 emissions on 2008.
Carbon spray probably would help if sprayed in a right place but I am not gonna lie that would have to be near exhaust manifold where the exhaust gas comes to egr cooler. As the exhaust gas flow it's like this exhaust manifold->>>>egr cooler->>>>>egr->>>>>inlet manifold so you would want to spray it in to egr cooler so that it would go through it and then egr. I have used some in 1.6hdi but no good results at all I tried a few.
@@Mad4FrenchCars Thank you for the reply. 1. Is there anyway to tell whether the valve has physically failed or simply is not able to close and open properly due to carbon build up. FYI my codes are P0402, P0488, P0490, P00409 resulting in acceleration hestitation. 2. Is removing the EGR valve and cleaning and or replacing a difficult job. I ask as I am not a mechanic and am told by garages it is a 2 hr job, is that true?
@@rwhite5529 2hours might be a bit excessive but if they are not very confident in what they are doing then it sounds about right. Removing egr is not a big deal it would have a clear indicators if it's physically damaged in any way or if its just a carbon build up. If it's just a carbon build up the. Once it's cleaned it should be OK. If damaged then replacement egr will be needed but until you get a replacement one you could blank one you have by inserting a metal plate between engine block and egr and it would drive as normal but that's more temporary solution also need to know your euro standard as then you know if blanking plate needs to have 10mm hole in it or not.
@@Mad4FrenchCars Thank you for the reply. Can I ascertain whether the valve blocked or physically failed from the codes and symptoms or is physical inspection the only option
@@rwhite5529 to be fair mate codes will be quite similar for phisical fail and carbon build up as if its open stuck either way code will be same. If you have plastic cover on a back of egr you could take that off before removing egr and move it with fingers to see if its moving there can also be a problem with a connector going to egr. But I would personally take it off and inspect it.
You are right, all I am saying is if you do a proper egr delete and remove egr and egr cooler all they need to do is have a sneaky peak behind the engine and they know its not there. Blanking plate passes mot as they not gonna remove any pipes or egr (as you mentioned) to see if its blanked so you will be OK.
@@Mad4FrenchCars That is true, if they can see it, they can fail it, but they can't fail what they can't see. That's how I look at it. If it passes the viscocity test, then happy days
@@daveyboiyeah I have had a blanking plate on 2 of my 407s before with a plate it passes no problem, I have never tried to remove it properly and try to pass it.
@@AcePanda01 normally people do a egr and dpf delete together. Adjustments have to be made prior remapping it. Dpf has to be gutted out and egr usually blancked from both sides but with newer engines is more and more complicated to do it properly. As newer engine egr is different and also some has add blue and stuff you get other problems after doing any removals
@@Mad4FrenchCars also bough a 180hp chip enhancement, will need to change it Back for contrôle technique (MOT) , But why not, it won't give 180, probably about 165-170hp , but ABIT more power won't hurt

If damaged then replacement egr will be needed but until you get a replacement one you could blank one you have by inserting a metal plate between engine block and egr and it would drive as normal but that's more temporary solution also need to know your euro standard as then you know if blanking plate needs to have 10mm hole in it or not.
@@Mad4FrenchCars Thank you for the reply. Can I ascertain whether the valve blocked or physically failed from the codes and symptoms or is physical inspection the only option
@@rwhite5529 to be fair mate codes will be quite similar for phisical fail and carbon build up as if its open stuck either way code will be same. If you have plastic cover on a back of egr you could take that off before removing egr and move it with fingers to see if its moving there can also be a problem with a connector going to egr. But I would personally take it off and inspect it.
MOT centres can't remove anything from the car. They can only tell by the smoke viscocity test
You are right, all I am saying is if you do a proper egr delete and remove egr and egr cooler all they need to do is have a sneaky peak behind the engine and they know its not there. Blanking plate passes mot as they not gonna remove any pipes or egr (as you mentioned) to see if its blanked so you will be OK.
@@Mad4FrenchCars That is true, if they can see it, they can fail it, but they can't fail what they can't see. That's how I look at it. If it passes the viscocity test, then happy days
@@daveyboiyeah I have had a blanking plate on 2 of my 407s before with a plate it passes no problem, I have never tried to remove it properly and try to pass it.
@@Mad4FrenchCars my 307 CC has a blanking plate and pipe removal. Only thing I noticed, is they tend to whine when not on boost
@@daveyboiyeah Interasting
What size is the hole?
Hi have Peugeot 2.0 hid 180 hp seen I’m euro 6 would plate with hole work for me
Car 2015
@@ricardomarques2044 not sure but in theory it should
Euro 6 2.0 hdi I have had deleted. Do I need to blank it too or do anything else
I have not done it on a euro 6 yet so not sure but who ever mapped it out should have told you what needs to be blanked or removed really
@Mad4FrenchCars I'm not sure they know. I've had problems since with the dpf so I'm considering having it put back in with a new egr.
@@AcePanda01 normally people do a egr and dpf delete together. Adjustments have to be made prior remapping it. Dpf has to be gutted out and egr usually blancked from both sides but with newer engines is more and more complicated to do it properly. As newer engine egr is different and also some has add blue and stuff you get other problems after doing any removals

Very well explained and filmed.
Because I have the valve cover off at the moment, I went to go & clean the egr this morning, only to find previous owner had already done this 😂😂
I bet it was nice to find it clean
@@Mad4FrenchCars also bough a 180hp chip enhancement, will need to change it Back for contrôle technique (MOT) , But why not, it won't give 180, probably about 165-170hp , but ABIT more power won't hurt
@@No-timeforimbeciles Sounds good I have never tried them chips myself. Normally just get a remap on a ecu stage 1 gives about 165-175bhp.
@@Mad4FrenchCars these are supposed to be. 'plug & play' but will not pass MOT, so just change for original for that
@@Mad4FrenchCars am being held up, cam cover gasket set has not arrived yet, nor the injector crush washers or camshaft oil seal, annoying !
That’s a 1.6, not a 2.0. Even says on the engine cover
Its 2.0hdi its 16 v as sixteen valve not 1.6
