@@mattperry7821officially no …. If you delete the egr on the map leave it in place then if gut the dpf and they can’t see how you did it then yeah it will pass
When I did a egr delete and a step 2 remap on my 2006 Audi A6 D3 4.2 TDI, it got lower emissions... it run a little hotter (positive) and the fuel milage got alot better... And it stopped dumping so down the intake... And that car passed MOT no problem at all! It had even cleaner exhaust after the tune and egr delete..
I find after the EGR delete releases alot of white smoke when your parked at the traffic lights and has a strong smell when driving no issues actually has more power and fuel economy
@@MrPrime-mt8dd Instead of removing the whole thing, you just find a way to block it closed Most people just plug the vacuum line that controls the EGR so it can't open anymore It's almost free and very easy but illegal af if you live in Europe
I know over 100 people that had it done properly with a remap and not one was caught yet as they are tiny little minority considering that the wast majority of people have no idea and will never touch the car .
I’m proud mine is deleted and am reaping the rewards with a better running truck better fuel economy and the longevity of my vehicle ! The laws were meant for the trucking industry and larger vehicles like busses and heavy equipment and had to include the 2 ton and smaller because of legalities !
Disconnected the EGR vacuum hose from on my E92 320d N47 engine and done about 300km. So far no engine lights have popped up. Noticeable gain in power and MPG. Dont forget to seal the vacuum hose using a screw or something.
Deleding the EGR or blocking the EGR Pipe to the intake manifold does allways have a positive effect to the engine. Important to know is that the EGR system on all these enginges is only letting exhaust gasses into the intake manifold when you are driving it at partial load range (city) or when the engine is not fully warmed up. EGR is allways closed under full load (highway). Diesel engines with DPF System dont like to be run only in partial load range, because no DPF regeneration can be run under this conditions. But only at partial load conditions the EGR is active. And this is one of the main reasons why so many modern engines break down after only some 100.000km. The costs and emmisions produced because of all the addtional repairs and needed spare parts caused by this ERG "nonsens" outweight the emmision benefits of any EGR system BY FAR.
I've done it on my ford focus mk2 2.0 tdci as kept failing to regen dpf due to exhaust gases not getting hot enough! Well that's what I was told by a dpf specialist since removing it dpf has not failed to do a regen, car has a remap which put it too around 162bhp with dyno graph and its got 195k on the clock My mpg has gone up about 3-4 depending on how hard i accelerate, my emissions with egr delete are 0.51 and limit applied was 1.50 is good as it had egr it failed emissions but with it off it was around 0.76. When replacing an injector my friend had a one if them micro cameras to see how bad carbon was there was a lot but nothing much for 194k also intake system is less oilly and no crude so I say its great! I also do around 525 miles a week with car averages 48mpg so I say go for it!
It is not illegal ro remove the EGR, but maybe commiting an offence to use the vehicle with the EGR removed. Put it this way, many wouldn't be able to tell if someone has deleted the DPF, if done right, same applies to EGR, blanking plate, map out and leave the EGR connected. Removal of the EGR actually reduces the amount of soot and an MOT test for a diesel car measures smoke and soot content. I work in the motor trade and EGR's cause so much problems by the fact that they allow carbon and soot to enter the inlet and all the associated pipe work including the EGR itself.
Do a sleeper disable.. Don't delete or remove anything; just disable it's operation at a key point without it being visibly tampered with. If you go to sell the car or need an inspection, re-enable. Personally, if a person is going to run an engine harder because of an EGR choke, wouldn't nearly the same emissions come out, vs having more low end torque and being a little more conservative?
Blanked the egr on a audi tdi after the emission fix update when the egr failed and the shop said it would cost over 1000 Euros... Without egr the engine is a little noisier but the air intake gets really clean after a few thousand kilometers
I can't see the point of feeding exhaust back into my engine where dirt will mix with the oil and wear out parts, mines been blocked for a while going to leave it as is.
I blanked off both ends of my cooler and got a tune that disabled the EGR valve. Technically it should make the cooler last longer because there's no more exhaust flowing through it, just coolant.
I drive a pd140 leon with a straight pipe, egr blank and stage 1 map. Very little smoke and most mot stations just do a visual test for diesel cars when it comes to emissions so mine passed without issue
i’ve got a PD bew that i just put some home made plates on. took the cooler out and mated the coolant lines. i have a digital multi gage plugged in my car that says boost and temps etc…. should i be worried about temperatures? coolant temps have been good since i did it, and i haven’t seen anything crazy. why is everyone talking about high temps? i’m getting it tuned here in 2 weeks. is there anything i should say to my tuner?
@@alinutzalin6346 it went really well. i told him to erase it from the ecu, along with removing the seatbelt chime. they were very nice and didn’t charge extra for it. it’s been holding up really well and i haven’t seen any heat issues🙌
So in essence do NOT remove the system. Just fit a blanking plate on the exhaust port or have it mapped to stay shut. Simple. Both mods that are hard to spot and very easy to reverse.
Yes I did this in the 1980's on cars, and wondered why removing it was wise, if you just blank it, the car can think it's working all day but no gas passes. I just wondered if the ECU tunes the car to "expect a % of gas". ??? Anyone tried this.
@@iangillott Depends on the car, some cars do have sensors for the air that goes through the EGR, if anything out of spec is going on there, it might force you into limped/limited mode. It's always a good idea to adjust for the change, air composition always change from default specs when you stop hot (less dense) air from entering the engine.
Not a bmw but i was driving across europe in my volvo, and the egr valve got stuck open in germany, barely managed to get of the bahn, after some head scratching i used a coke can to block the egr pipe, been like that over a year since i cant find the funds for a new egr valve, but since its so discrete no one can see its been done, sooo yeah, its good
@@DirtyGrandPaz out of sheer desperation haha! Got a a paperweight with no means of getting it moving, i was panicking, but had a litter of some german beer, a few ciggies relaxed my thoughts and started brain storming 😃 firstly blocked off the egr connection with some tape, started the car and it ran perfectly, got a coke can, cut the bottom out and flattened in with a hammer, cut it to the shape of the connection and boom, off i went 😃 the whole process took about 5 hours. Long story short, this can be applied to many things in life, panic will only make things worse, a clear mind will always find a solution.
@@Elmantukas Well, thanks for the quick response mate. German beer and some ciggies can work wonders, for sure. 😄 And regarding Panic you are absolutely right. Stay calm, makeup your mind and there will always be a way. Cheers
With a Bmw Diesel put in the best fuel, add some Liqui Moly Diesel boost and clean, change oil every 6000 miles or less, ( so easy to do it yourself ), with LL04 oil 5W-30, get Carly bluetooth obd 2 and do a simple dpf regen yourself when youbgo for a longer motorway run. You'll never have a problem.... If you bought a used Diesel thats just sat in traffic doing short runs remove egr, use vacuum cleaner hose to suck all the crap, spray with brake cleaner, when dry vacuim again and apply then fully service....these engines will do 300,000+ miles easily if properly looked after. If you put in crap oil, cheap diesel, don't service regularly and drive around town so dpg cant regen properly you are guaranteed trouble...
@@TheFentonj every 2nd or 3rd tank full. If driving around town and mainly commuting every 2nd tank. I use 10ml per 10L...if you use too much you'll end up damaging the injector nozzles over time so check the dose carefully with the measuring cup built into the lid of the Clean & Boost. You also want to make sure the engine oil gets up to operating temperature this will prevent condensation and water build up in the engine especially in winter...
Basically the idea of the ega is to limit the amount of oxygen introduced into the combustion chamber by adding exhaust gasses. This limits the nitrogen oxide produced to the atmosphere, Remember 74% of the air we breath is nitrogen !
That seems right. Essentially a certain horsepower engine is reduced to a smaller engine by the EGR system. A bigger engine reduced by EGR bottlenecking could essentially be as powerful as your unchoked smaller engine. Why did they make EGR necessary when they could have sold us smaller engines? Seems a ton of material and expense could have been saved, not to mention lengthening the life of an engine without this choking; seems like planned failure and not necessarily smog control.
George Austers One problem of EGR removal is quick DPF regen unless you have deleted DPF too. Just removing EGR will screw DPF soon due to increased shoot.
Depends on the garage but many are becoming more strict due to government rules on checking that the DPF etc. are intact and operating correctly, it is no longer just the visual smoke test that diesel cars have to pass.
@@catalinacatalina1474 Yes, car may try more active and passive regen but due to prerequisites (75 degree above engine temp + 10 ltr fuel plus, certain speed limit for a continuous-time), this can be a recipe for disaster unless you drive only on motorways. The outcome can be blocked DPF and failure. Also, more regen will put pressure on the oil lubricity as exhaust gas temp will raise more frequently above 550-degree celsius. My advice would be keep both EGR and DPF on but maintain them with efficient combustion so that shoot production is less and burn off. If you are interested I can make a video on how to best maintain modern Diesel with the DDE system.
Just get a remap that disables the valve so everything looks stock and the fuelling gets adjusted to maintain safe temperatures , as a bonus you will get better running engine , more power and better fuel economy and the best bit no more crap build up in your intake that will half the lifespan of your engine ! If you just block the EGR without remap your temperatures will go up and that’s no good !
Yep... and spark plugs 1 step colder.. maybe mishimoto oil cooler and better aluminium radiator keep everything stable. Exhaust is better to upgrade too.. header and metallic catalytic converter. Those parts working better when exhaust gas is hotter.
Have readout a car with simply blocked EGRvalve without remap on some conditions. the EGT was not significant hotter ( roundabout 50-70°C. more on highspeed conditions ) sometimes cooler as before with correct working EGR. Significant lower was the engine noise in Town traffic. More Power I haven't felt but the revup between 1500 and 2000 RPM is much quicker and the consumption is dropped from 6.9L/100Km to 6.4L/100 Km (measured on the self route with nearly self conditions) The other Temps...(.Engine Oil and Coolant ) are the same as before. ( Water between 84 and 89 and oil between 92 and 103°C.) The OBD based main inspection was without objection
@@milesxc17 Its very simple, just remove the black rubber tube that goes to your EGR. Just pull it off. But dont forget to plug the end of the rubber tube with a bolt, because its a closed circuit. The hole on the EGR can be left open.
@@MrPrime-mt8dd There is a tube that goes to the EGR valve, you take that tube off and plug it, thats your EGR delete. Otherwise you and replace the gasket between the EGR and the intake with a piece of steel from a drink can.
Well, what the EGR valve does is that it lowers the oxigen percentage in the combustion, that resorts to a lower burning temperature and that lower burning process produces less NOX and less CO2.
CO2 is fully burnt carbon and is actually really good for the environment. So recirculating the exhaust gases will likely produce more CO2 as the half-burnt carbon (CO) is reburnt and converted to CO2.
JUST DELETE EVERYTHING AND YOU WILL HAVE A BETTER VEHICLE 🚗 💨. I DID IT TO MY X5 35d. And runs way better than before. Two year and no problems in. TX if its diesel. No problem with the smoke 💨
I had a 1998 2.2 Subaru sohc legacy that didn't come stock with an EGR valve, therefore I honestly don't believe there's "negative effects" to an EGR delete. I deleted my EGR on my previous 04 Subaru outback and I noticed considerably more power (especially on the highway) I'm blocking it off on my 09 Subaru and tuning out the CEL so it's as if it never existed, the horrible build up of exhaust sludge on the inside of my intake manifold is enough motivation on its own..
Making it illegal is stupid all the egr and dpf do is cost more money when it goes wrong , I've seen so many in the workshop because these pack up and cost a load to fix
Its not illegal as far as your engin is under the emission level!!!!!! Do what ever you want but check your emmision!!!. Ask helicopters to install exhayst sytstem , because they do so mouch noise by flying above my aeria;)
I know it's illegal but I've fitted the egr blanking plate as tbh it does create carbon build up in the intake and in the valves and I've also hollowed the dpf but I haven't welded or cut it open to do it but tbh the dpf is a stupid thing when it's regenerateing it's still releasing diesel into the atmosphere
@@ozgnpalkbnydn yes as it's been smashed through it hasn't been cut n welded I just make sure it's up to temperature before mot as a diesel is just a smoke test which it hardly chucks out any smoke
So, other than the legal side of it, there is no downside to an EGR delete. About to do it on a Freelander td4, will let you know. We don't have the MOT and Emissions Compliance issues in SA that you have in the UK, so no worries there for me.
Hello sir, if you delete EGR just with EGR blanket plate, DDE will give a error : "Fault in the exhaust-gas recirculation" and your turbine will we always bypassed (open, no boost pressure). I will advise you to do a diagnose scan, just to see if any code is active.
EGR doesn't just reduce emissions, it actually makes your engine runs cooler, and increases fuel efficiency, which comes with a cost obviously, by using the recirculated 'mixture' it will implicate an less 'cleaner' load into the system, with less potential than a cleaner one, but it will burn cooler, and with less fuel injected to the load. This power loss is sometimes practically unnoticed, this EGR are very effective systems, that help your car being more fuel eficcient and also reduces emissions. Removing it, or keeping it blocked or uncleaned might cause all sorts of problems, being that your engine will run hotter, less fuel efficiency, and more emissions. This delete can be done safely, but the ECU definitely needs to be reprogrammed, and it will have its pros and cons. What I fail to understand is that there's some sort of common sense about EGRs being just for reducing emissions and that recircles unwanted dirt into the motor, if you think this is it, than you know nothing about how these systems really work, and very few knowledge about the mechanical engineering envolved on a combustion motor... inform yourself with valid information and know how before going out saying stuff like this as if you know what you're talking about...
I had e60 530d egr delete whilst having an off the shelf remap stage 1 and carbon clean deal with a at home call..carbon clean and remap perfect..i blanked off egr (proper coked up with glunge )..The re code turns off the vacuum if im not wrong to the egr BUT in turn on the e60 the engine mounts work via the same vacuum ...you will get vibration at idle and low revs
@@tomislavprof9734 an intercooler is to cool the air down to reduce turbo lag granted not by much but the main purpose is it help the turbo boost properly by giving it the pressure on the cold side
Correct me if im wrong but a lot of BMWs have egr "hidden" under the engine cover and MOT control is forbiden to mess with your car so they have no way to find out if the EGR is blanked as they can't remove that cover. I guess same goes for any other control.
MOT is allowed to remove covers that use clips etc providing they are not required to unscrew anything and only if there is no risk of breaking the cover
Got BMW 320d e92 coupe and it's eating fuel and I think getting egr and Darkside Development to install it will be good, they are so many modified cars near me and most of them just drive upto Doncaster and get DS Development to do custom remaps, big turbos etc, I've spoke to them and they have said best getting egr,dpf, custom remap if I'm wanting more mpg, removes any clogs, and won't have any issues, I did it on old golf I had and never got pulled up to get engine check, didn't ask for RAC the car is fine 😂
one thing I don't get is how deleting it increases mpg I get that it has more combustable stuff in there but, wouldn't reusing stuff with a little energy use less fuel?
The engine doesn't have to work as hard because the fuel is more potent. If we had an egr fitted to our lungs (lgr) We would be breathing faster walking down the street to get the required amount of oxygen.
If you build a gasket for the part of the EGR system that attaches to the exhaust that has no holes in it so no exhaust gas can pass through to the EGR system the system will not work the computer will think that it's working and if you do get stopped at a checkpoint they will look in all the stuff will be there and they will not know the difference and as far as knowing the difference there is no difference in power or performance because the second you hit the gas pedal and call for power the computer shuts the system down automatically the only time the system is working is when your pedal is at half throttle and you're not using all of the power of the engine anyway the only reason I would delete the EGR system is because when the Val fails and it is allowing exhaust gases to come into the engine at idle it will run extremely bad
my engine was running hot on highway .also I smelt fuel every so often I disconnect the egr valve it runs cooler again.. the egr and egr sensor needs replacing
I done the delete and removal of both the EGR and the DPF, they are nothing but problems, can cause issues to your engine along with rough idle if not cleaned
@@pulis2000 nope no trouble, just got to make sure it's done right, you can have it bored out without having to cut it open so the mot guys don't notice.
I’ve always bypassed this system this is due to the problems and expense I’ve had with them I’ve resantly been pulled and they didn’t notice luckily going by youre video but yh
Its safer then to put a blank plate in and then the ecu still thinks the egr is their so it can not be found electronically. And if you did get stopped and checked take out a flat bladed screwdriver undo 1 clip and take out the blank, and put the pipe back on done
Mate I'd give your engine a clean, it's a disgrace. The EGR can stay in place, you just block off the required areas with the EGR still in place. Not going to get spotted on a VOSA inspection as it's all there and present. It can also be done purely by software where the ECU is instructed to keep the EGR valve closed at all times. achieving the same thing. You need to mess with the ECU if you do it mechanically anyway as your EML will be on with a ECU fault.
Yes remap is the key if done properly , most people don’t understand what the EGR does and how it affects the air fuel ratios , if they just block it it will cause issues , remap is a must !
Hi. Great video and info. I have a 06 passat 1.9 tdi. I'm thinking if an egr and cooler delete. In South Africa they don't worry about the emissions as much. Would you recommend this delete? I belive only other con will be that the car will run hotter. Thanks
MOT can't tell a difference if the egr is blocked or not. Unles there is some clearly visible missing parts. Or a trouble code. Some dont even mesure NOx. For the effect on an engine. For four different engines, all petrol no diesels. Havent noticed a difference, nothing have changed. Only the intake manifold may be not as full of soot.
Back then yes now no emissions are lean and faul mot like mine as every year 5 years found mine zafira blanked my mot garage let it go this time found the last owner blanked mine had it 5 years garage said burning oil but spark plugs tell me different dont have to top up off going to put it back on emissions more leaner
My E46 330D is really low on power getting up to speed, anything under 3000 revs is so so slow! It’s had an EGR delete. I’m thinking off adding it back on. Any ideas?
@@null643 it was deleted when I got the car. I need to investigate it more to see how it was done. I’m thinking of replacing all of my vacuum hoses hoping that might help. Can’t understand where all of them go and this random sensor that doesn’t seem to do anything. Only had the car week and 1/ half
Well explain. Thanks for the video. I went to buy a used car. The seller told that EGR was blocked. Than I said that might effect the PDF filter regeneration. He then revealed that PDF was also removed. I simply run away. Question, will “removing” EGR effect the DPF? I was told that DPF will get blocked easier?
No, DPF will actually be LESS likely to block. EGR is designed to lower combustion temperature and also reduce oxygen levels, however it is difficult to get stoichiometric burn, so with EGR, the exhaust is actually sootier. With full cylinder of fresh air, diesel burns more cleanly hence less smoke,.. and hotter. So your DPF has less soot, is hotter for regen and the turbo should spool up a tiny bit quicker.
No guys, don't delete your EGR systems. 1 You won't gain any power. EGR valves only open under low load, when you are not asking your engine for power. 2 You're not introducing anything harmful to your engine. Anything the EGR system puts in your combustion chamber was in your combustion chamber not 1 seconds ago. 3 The EGR system lowers combustion temperature while simultaneously reducing fuel consumption. To put it briefly, if a portion of your cylinder's volume is filled with exhaust, the MAF will detect a reduction of oxygen flow, and the ECU, knowing the EGR is open will advanced your spark and squirt less fuel. Result = less combustion = lower temperature and added efficiency as a benefit. 4 You will reduce your power output. Let's say you do 3 highway pulls with a brief rest of coast/cruise in between each. Your EGR system would have opened during your low load situation, cooling your cylinders as described in point #3. Except now its not! Each successive pull will be slower and hotter.
Exactly. Efficiency is also lost due to higher pumping loss without an egr during low load situations. And if your combustion chamber is dirty, some cars can even experience light knocking due to much higher combustion chamber temperature.
a good tuner can map it so the EGR stays SHUT at all times essentially the same as a blanking plate the gasses hit a wall and can't go back through the engine, Jason at BWChiptune near London or Stan from Ecotune in Glassgow can do it for sure, I'm not sure about other reputable mappers though
for everyone who want to do egr delete you should also remove dpf and snap on downpipe, because you're dpf would get clog over time and you will lose power
mrjb7789 You live in a bubble you simply remove the Dpf cut it open from the top hallow it out weld it back together at the top and refit the mot tester can not see the top side of the Dpf many many cars have passed mot this way
Mr330d what about when he uses a emissions detector to see how much is coming out and it’s higher than it should be? I mean the tool they put in the tail and hooked up to computer
mrjb7789 I know what you mean but however in Northern Ireland anyway Only petrol cars and lorries/busses get emissions tested don’t ask why diesel cars don’t because a lot of young chavs are driving around with “smoke maps” installed 😂 that look like total shit In England Do Diesel private vehicles get emissions tested ? 🤔
Mr330d surprised they don’t to be honest, they do in England at least, brought in new rules and stricter tests, probs because light of the VW emissions scandal. In the MOT here if they see any bit of smoke it’s a fail before they even put the sensor in the tailpipe
you can map it out and blank it in such a way that you can't tell it's been done. also if your car is still fitted with a DPF you should NOT remove the EGR system, you'll block your DPF.
Thinking of having this done at the same time as a remap on my Jaguar V6 3.0 but someone mentioned that deleting the EGR can result in DPF issues further down the line. Any truth to this?
I just took the egr off my car rover 75 diesel to clean it to find its the conversion ! It has been passing mot's but it still blows a cloud of smoke on heavy ecceleration . So what now !?
A rover 25 2.0 turbo diesel will easily pass emissions with no egr valve, and no maf sensor. With a resistor/paper clip bridging 2 of the maf sensor wire terminals. (i forget which two wires though) And Running on 20 psi boost. Totally stock with a cheap k&n copy air filter.. And it was shockingly quick for what it was.. I miss that car.. ☹ That is all i have to say on this matter.. Lol
If anyone wants this hackmod doing to their rover 25 TDI.. let me know.. I invented a better setup. And I will explain it to you in this thread.. But remember this- You HAVE GOT TO use high efficiency coolant, and you MUST let it warm up fully before you thrash it, and you must be mercifull or you will blow it up in seconds.. And no side-steping the clutch either!! or that gearbox casing is done for! If you want the trick, just ask nicely.. You might want a second turbo.. I was to scared to push it. Past 20psi.. But after seeing how far you can push a 1.0l ford fiesta, (190bhp) I wish I had gone harder!
It should only operate below 1500 rpm. The problem is short journeys and stop start traffic. Only get a diesel if your regular driving is more than 10 miles and you can get over 40 mph. Anything slower or shorter doesnt let the exhaust get hot enough to not have carbon build up. Saying that, the attempt to reduce pollution by making you have to clean it out anyway is rather stupid.
I can understand why people do delete the egr and remap it because it costs to much to replace the EGR. Now if the EGR is blocked up with carbon so doesn’t function then why are the vehicle manufacturers doing something about it to stop the EGR from blocking up in the first place. But yet the DPF gets rid of carbon by doing a reg but yet the rest of the engine gets clogged up so one problem is solved and moved to another area . Tomorrow I am having my EGR deleted and stage 1 remap done on my Vw passat 2013 2.0tdi because my EGR is on its way out and will cost £1100 to replace, my car has just done over 56k so in another 56k I’ll be spending another 56k on top of what ever else blocks up in the engine with carbon
i have egr delite kit on my golf mk4 and in my conty only thing that police is checking is disel fuel so im kinda safe but i have all original parts in my trunk bsc once per year on local car examination they make emission test so i put egr back on engine
How does it make sense to lower emission with something that increases the amount of fuel used and increases the chances of you engine failing. What a joke.
And I was contemplating about an egr delete on my 2010 Avensis..I just don’t like the idea of walking home if I get stopped..but question..can the DVSa dismantle the egr to see if it has been blanked..
We bought a vauxhall astra 2008 last November but it didn't have the egr valve, it's not missed a beat. We are going threw oil though, I've been told that it's not essential to have it on for a working car (forget that you need it for a mot) thoughts?
Hey Ally! You do technically need it for an MOT but the chances of a mechanic noticing it is gone or even caring that it has gone is very slim! cars generally benefit from having it removed! in terms of your oil consumption it could be a number of things so it is often worth taking a look at the forums to work it out 😁
I totally agree. I deleted mine on a 2006 Seat Ibiza 1.9 tdi FR and had it mapped out. With hindsight I should have just cleaned it properly and put it back on.
I don't have the answer to this, but your question raises an idea. If the EGR system clogs up it's essentially not recirculating gases and essentially self deleted. However you may need to clean the intake passages carefully not unplugging the EGR passage. haha.. If anyone asks about your EGR, I guess it's plugged.. doh!
Can you just clean it and leave it there but remove off ecu. Will that be fine? Just to take it off ecu but just clean and leave it. Would I have any problems?
If it's a single entry port put the blanking plate in and put the valve back over top so it looks like the valve is in situ and working. Have it deleted from the ECU and voila. VOSA or whoever's only do a visual check.

Well that's what I was told by a dpf specialist since removing it dpf has not failed to do a regen, car has a remap which put it too around 162bhp with dyno graph and its got 195k on the clock
My mpg has gone up about 3-4 depending on how hard i accelerate, my emissions with egr delete are 0.51 and limit applied was 1.50 is good as it had egr it failed emissions but with it off it was around 0.76.
When replacing an injector my friend had a one if them micro cameras to see how bad carbon was there was a lot but nothing much for 194k also intake system is less oilly and no crude so I say its great! I also do around 525 miles a week with car averages 48mpg so I say go for it!
Here in the states, not every state has emissions or inspections so some of us can do lots of illegal stuff to our cars.
lucky you lol
Canada too. Pretty sure emissions tests were struck down federally
@@RandomlnternetGuy We can't even use bigger rims dude, unless you pay for it xd.
Yeah like Florida , explains all the rubber by the side of the freeways due to burst tires , absolutely retarded not having inspections

It is not illegal ro remove the EGR, but maybe commiting an offence to use the vehicle with the EGR removed. Put it this way, many wouldn't be able to tell if someone has deleted the DPF, if done right, same applies to EGR, blanking plate, map out and leave the EGR connected. Removal of the EGR actually reduces the amount of soot and an MOT test for a diesel car measures smoke and soot content. I work in the motor trade and EGR's cause so much problems by the fact that they allow carbon and soot to enter the inlet and all the associated pipe work including the EGR itself.
Do a sleeper disable.. Don't delete or remove anything; just disable it's operation at a key point without it being visibly tampered with. If you go to sell the car or need an inspection, re-enable. Personally, if a person is going to run an engine harder because of an EGR choke, wouldn't nearly the same emissions come out, vs having more low end torque and being a little more conservative?
I put a gasket without a hole between the egr and intake manifold. It's a sleeper install and works like a charm. 04 mustang gt
Blanked the egr on a audi tdi after the emission fix update when the egr failed and the shop said it would cost over 1000 Euros... Without egr the engine is a little noisier but the air intake gets really clean after a few thousand kilometers
I can't see the point of feeding exhaust back into my engine where dirt will mix with the oil and wear out parts, mines been blocked for a while going to leave it as is.
How about the ecu causing the engine light to come on?
@@denniero6904 you can disable it if you know how to program them.

@@adamluma8937 yeah should do. more fresh air and less crap is burning however haven't dyno'd it to get figures.
I blanked off both ends of my cooler and got a tune that disabled the EGR valve. Technically it should make the cooler last longer because there's no more exhaust flowing through it, just coolant.
Pls explain how you blanked the cooler... Mine is leaking in the EGR system and would like to do the same once I do an EGR delete remap
@@ikbarbershop if it’s leaking coolant there’s no blanking to be done, replace it or weld it or something.
@1tokeover Thanks my friend
I drive a pd140 leon with a straight pipe, egr blank and stage 1 map. Very little smoke and most mot stations just do a visual test for diesel cars when it comes to emissions so mine passed without issue
i’ve got a PD bew that i just put some home made plates on. took the cooler out and mated the coolant lines. i have a digital multi gage plugged in my car that says boost and temps etc…. should i be worried about temperatures? coolant temps have been good since i did it, and i haven’t seen anything crazy. why is everyone talking about high temps? i’m getting it tuned here in 2 weeks. is there anything i should say to my tuner?
@@jaxon.frandrup How'd it go?
@@alinutzalin6346 it went really well. i told him to erase it from the ecu, along with removing the seatbelt chime. they were very nice and didn’t charge extra for it. it’s been holding up really well and i haven’t seen any heat issues🙌
So in essence do NOT remove the system. Just fit a blanking plate on the exhaust port or have it mapped to stay shut. Simple.
Both mods that are hard to spot and very easy to reverse.
Yes I did this in the 1980's on cars, and wondered why removing it was wise, if you just blank it, the car can think it's working all day but no gas passes. I just wondered if the ECU tunes the car to "expect a % of gas". ???
Anyone tried this.
@@iangillott Depends on the car, some cars do have sensors for the air that goes through the EGR, if anything out of spec is going on there, it might force you into limped/limited mode. It's always a good idea to adjust for the change, air composition always change from default specs when you stop hot (less dense) air from entering the engine.
@@iangillott That’s why you get the ECU reprogrammed when you blank it off. It’s all part of the mod conversion..
Not a bmw but i was driving across europe in my volvo, and the egr valve got stuck open in germany, barely managed to get of the bahn, after some head scratching i used a coke can to block the egr pipe, been like that over a year since i cant find the funds for a new egr valve, but since its so discrete no one can see its been done, sooo yeah, its good

@@DirtyGrandPaz out of sheer desperation haha! Got a a paperweight with no means of getting it moving, i was panicking, but had a litter of some german beer, a few ciggies relaxed my thoughts and started brain storming 😃 firstly blocked off the egr connection with some tape, started the car and it ran perfectly, got a coke can, cut the bottom out and flattened in with a hammer, cut it to the shape of the connection and boom, off i went 😃 the whole process took about 5 hours.

With a Bmw Diesel put in the best fuel, add some Liqui Moly Diesel boost and clean, change oil every 6000 miles or less, ( so easy to do it yourself ), with LL04 oil 5W-30, get Carly bluetooth obd 2 and do a simple dpf regen yourself when youbgo for a longer motorway run. You'll never have a problem....
If you bought a used Diesel thats just sat in traffic doing short runs remove egr, use vacuum cleaner hose to suck all the crap, spray with brake cleaner, when dry vacuim again and apply then fully service....these engines will do 300,000+ miles easily if properly looked after.
If you put in crap oil, cheap diesel, don't service regularly and drive around town so dpg cant regen properly you are guaranteed trouble...
Hi how often do you put in liqui moly
@@TheFentonj every 2nd or 3rd tank full. If driving around town and mainly commuting every 2nd tank. I use 10ml per 10L...if you use too much you'll end up damaging the injector nozzles over time so check the dose carefully with the measuring cup built into the lid of the Clean & Boost. You also want to make sure the engine oil gets up to operating temperature this will prevent condensation and water build up in the engine especially in winter...
If l do that l will be a dead man walking get the wife's hover cruddy not good.
Basically the idea of the ega is to limit the amount of oxygen introduced into the combustion chamber by adding exhaust gasses. This limits the nitrogen oxide produced to the atmosphere, Remember 74% of the air we breath is nitrogen !
nitrogen isn't nitrogen oxide...
Nitrogen Oxide is produced when you introduce too much oxygen during combustion !
It also lowers combustion temperatures which reduces nitrous oxide formation.
That seems right. Essentially a certain horsepower engine is reduced to a smaller engine by the EGR system. A bigger engine reduced by EGR bottlenecking could essentially be as powerful as your unchoked smaller engine. Why did they make EGR necessary when they could have sold us smaller engines? Seems a ton of material and expense could have been saved, not to mention lengthening the life of an engine without this choking; seems like planned failure and not necessarily smog control.
@@onepercentileyes, very true!
EGR removal won’t cause you to fail an MOT mate, same with your DPF being gutted providing that your engine is healthy and not running rich👍🏻
George Austers One problem of EGR removal is quick DPF regen unless you have deleted DPF too. Just removing EGR will screw DPF soon due to increased shoot.
Depends on the garage but many are becoming more strict due to government rules on checking that the DPF etc. are intact and operating correctly, it is no longer just the visual smoke test that diesel cars have to pass.
Will EGR off produce more soot in to the DPF?
@@dukemaximus1639 so with EGR off car will make more regens ?
@@catalinacatalina1474 Yes, car may try more active and passive regen but due to prerequisites (75 degree above engine temp + 10 ltr fuel plus, certain speed limit for a continuous-time), this can be a recipe for disaster unless you drive only on motorways. The outcome can be blocked DPF and failure. Also, more regen will put pressure on the oil lubricity as exhaust gas temp will raise more frequently above 550-degree celsius. My advice would be keep both EGR and DPF on but maintain them with efficient combustion so that shoot production is less and burn off. If you are interested I can make a video on how to best maintain modern Diesel with the DDE system.
Just get a remap that disables the valve so everything looks stock and the fuelling gets adjusted to maintain safe temperatures , as a bonus you will get better running engine , more power and better fuel economy and the best bit no more crap build up in your intake that will half the lifespan of your engine !
If you just block the EGR without remap your temperatures will go up and that’s no good !
Yep... and spark plugs 1 step colder.. maybe mishimoto oil cooler and better aluminium radiator keep everything stable. Exhaust is better to upgrade too.. header and metallic catalytic converter. Those parts working better when exhaust gas is hotter.
I blanket egr on a couple of different cars no over heating problems what so ever maybe 5c which is no problem.
Have readout a car with simply blocked EGRvalve without remap on some conditions. the EGT was not significant hotter ( roundabout 50-70°C. more on highspeed conditions ) sometimes cooler as before with correct working EGR. Significant lower was the engine noise in Town traffic. More Power I haven't felt but the revup between 1500 and 2000 RPM is much quicker and the consumption is dropped from 6.9L/100Km to 6.4L/100 Km (measured on the self route with nearly self conditions)
The other Temps...(.Engine Oil and Coolant ) are the same as before. ( Water between 84 and 89 and oil between 92 and 103°C.)
The OBD based main inspection was without objection
if you disable the egr would the dpf be clogged faster.
Thanks
@@erjonsyla802 no it won't it will clog less' blocking the egr valve will increase combustion temperature which in turn will produces less soot.
Well don't remove it, just blank the damn thing :D
Remove the pipe that opens the valve. Poor man's EGR delete.
@@kevin.afton_ Anywhere I can find more info on how to do this? Preferably with pics
@@milesxc17 Its very simple, just remove the black rubber tube that goes to your EGR. Just pull it off. But dont forget to plug the end of the rubber tube with a bolt, because its a closed circuit. The hole on the EGR can be left open.
what do you mean?
@@MrPrime-mt8dd There is a tube that goes to the EGR valve, you take that tube off and plug it, thats your EGR delete. Otherwise you and replace the gasket between the EGR and the intake with a piece of steel from a drink can.
Well, what the EGR valve does is that it lowers the oxigen percentage in the combustion, that resorts to a lower burning temperature and that lower burning process produces less NOX and less CO2.
CO2 is fully burnt carbon and is actually really good for the environment. So recirculating the exhaust gases will likely produce more CO2 as the half-burnt carbon (CO) is reburnt and converted to CO2.
JUST DELETE EVERYTHING AND YOU WILL HAVE A BETTER VEHICLE 🚗 💨.

I had a 1998 2.2 Subaru sohc legacy that didn't come stock with an EGR valve, therefore I honestly don't believe there's "negative effects" to an EGR delete. I deleted my EGR on my previous 04 Subaru outback and I noticed considerably more power (especially on the highway) I'm blocking it off on my 09 Subaru and tuning out the CEL so it's as if it never existed, the horrible build up of exhaust sludge on the inside of my intake manifold is enough motivation on its own..

So, other than the legal side of it, there is no downside to an EGR delete. About to do it on a Freelander td4, will let you know. We don't have the MOT and Emissions Compliance issues in SA that you have in the UK, so no worries there for me.
My 123d is blowing black smoke and loss of power. Diagnostics point out dpf and egr issues. So it's all coming out next week 🤞 it sorts it
Hello sir, if you delete EGR just with EGR blanket plate, DDE will give a error : "Fault in the exhaust-gas recirculation" and your turbine will we always bypassed (open, no boost pressure).
I will advise you to do a diagnose scan, just to see if any code is active.
EGR doesn't just reduce emissions, it actually makes your engine runs cooler, and increases fuel efficiency, which comes with a cost obviously, by using the recirculated 'mixture' it will implicate an less 'cleaner' load into the system, with less potential than a cleaner one, but it will burn cooler, and with less fuel injected to the load. This power loss is sometimes practically unnoticed, this EGR are very effective systems, that help your car being more fuel eficcient and also reduces emissions. Removing it, or keeping it blocked or uncleaned might cause all sorts of problems, being that your engine will run hotter, less fuel efficiency, and more emissions. This delete can be done safely, but the ECU definitely needs to be reprogrammed, and it will have its pros and cons. What I fail to understand is that there's some sort of common sense about EGRs being just for reducing emissions and that recircles unwanted dirt into the motor, if you think this is it, than you know nothing about how these systems really work, and very few knowledge about the mechanical engineering envolved on a combustion motor... inform yourself with valid information and know how before going out saying stuff like this as if you know what you're talking about...
I had e60 530d egr delete whilst having an off the shelf remap stage 1 and carbon clean deal with a at home call..carbon clean and remap perfect..i blanked off egr (proper coked up with glunge )..The re code turns off the vacuum if im not wrong to the egr BUT in turn on the e60 the engine mounts work via the same vacuum ...you will get vibration at idle and low revs
It raises the mpg cos as diesel burns with heat and the hotter the better the burn so more fuel is burned so less need's to be injected
What is the funcion of intercooler in every turbo charged dieses engine? It looks that you are trooling here.
Sweet Jesus!!
@@tomislavprof9734 an intercooler is to cool the air down to reduce turbo lag granted not by much but the main purpose is it help the turbo boost properly by giving it the pressure on the cold side
Correct me if im wrong but a lot of BMWs have egr "hidden" under the engine cover and MOT control is forbiden to mess with your car so they have no way to find out if the EGR is blanked as they can't remove that cover. I guess same goes for any other control.
MOT is allowed to remove covers that use clips etc providing they are not required to unscrew anything and only if there is no risk of breaking the cover

Got BMW 320d e92 coupe and it's eating fuel and I think getting egr and Darkside Development to install it will be good, they are so many modified cars near me and most of them just drive upto Doncaster and get DS Development to do custom remaps, big turbos etc, I've spoke to them and they have said best getting egr,dpf, custom remap if I'm wanting more mpg, removes any clogs, and won't have any issues, I did it on old golf I had and never got pulled up to get engine check, didn't ask for RAC the car is fine 😂
one thing I don't get is how deleting it increases mpg I get that it has more combustable stuff in there but, wouldn't reusing stuff with a little energy use less fuel?
The engine doesn't have to work as hard because the fuel is more potent.
If we had an egr fitted to our lungs (lgr)
We would be breathing faster walking down the street to get the required amount of oxygen.
EGR blanked on my Volvo D4 passed two MOTs no issues whatsoever
Where did you get it done?
Emissions getting leaner now I won't
If you build a gasket for the part of the EGR system that attaches to the exhaust that has no holes in it so no exhaust gas can pass through to the EGR system the system will not work the computer will think that it's working and if you do get stopped at a checkpoint they will look in all the stuff will be there and they will not know the difference and as far as knowing the difference there is no difference in power or performance because the second you hit the gas pedal and call for power the computer shuts the system down automatically the only time the system is working is when your pedal is at half throttle and you're not using all of the power of the engine anyway the only reason I would delete the EGR system is because when the Val fails and it is allowing exhaust gases to come into the engine at idle it will run extremely bad
my engine was running hot on highway
.also I smelt fuel every so often I disconnect the egr valve it runs cooler again.. the egr and egr sensor needs replacing
I did that to my Audi S4 and it did get lil bit more mpg... Where I live there is no emissions
1:25 No mate, your thinking is back to front. It recirculates to reduce combustion temperatures in order to reduce NOx in the first instance/

Its safer then to put a blank plate in and then the ecu still thinks the egr is their so it can not be found electronically. And if you did get stopped and checked take out a flat bladed screwdriver undo 1 clip and take out the blank, and put the pipe back on done

Mate I'd give your engine a clean, it's a disgrace. The EGR can stay in place, you just block off the required areas with the EGR still in place. Not going to get spotted on a VOSA inspection as it's all there and present. It can also be done purely by software where the ECU is instructed to keep the EGR valve closed at all times. achieving the same thing. You need to mess with the ECU if you do it mechanically anyway as your EML will be on with a ECU fault.
Yes remap is the key if done properly , most people don’t understand what the EGR does and how it affects the air fuel ratios , if they just block it it will cause issues , remap is a must !
You don't have to remove the components, just insert blanking plates. So unless the inspector has a sharp eye , he or she will probably not spot it.
I don't think blank registration plates is going to help here
i thought DVSA can only stop and inspect commercial vehicles (vans/lorries) for spot checks.
In rural areas they sometimes check cars for red diesel but not that often, my mate had his checked.
Hi. Great video and info.

Would you recommend this delete?
I belive only other con will be that the car will run hotter.
Thanks
Did you delete it ?
MOT can't tell a difference if the egr is blocked or not. Unles there is some clearly visible missing parts. Or a trouble code. Some dont even mesure NOx. For the effect on an engine. For four different engines, all petrol no diesels. Havent noticed a difference, nothing have changed. Only the intake manifold may be not as full of soot.
Block it by using blanking plate.
Cheaper and easier method
Back then yes now no emissions are lean and faul mot like mine as every year 5 years found mine zafira blanked my mot garage let it go this time found the last owner blanked mine had it 5 years garage said burning oil but spark plugs tell me different dont have to top up off going to put it back on emissions more leaner
Does it just have to be there or does it actually have to work? Blank underneath the valve so it's still sat there but not working.
that's an interesting idea!

Yes it is more likely to block :)
I think you mean DPF
@@L_J_D23 Correct, thanks! I edited and fixed my question ;)
@@SmartProjectsABC 👍🏻
No, DPF will actually be LESS likely to block. EGR is designed to lower combustion temperature and also reduce oxygen levels, however it is difficult to get stoichiometric burn, so with EGR, the exhaust is actually sootier. With full cylinder of fresh air, diesel burns more cleanly hence less smoke,.. and hotter. So your DPF has less soot, is hotter for regen and the turbo should spool up a tiny bit quicker.
No guys, don't delete your EGR systems.
1 You won't gain any power. EGR valves only open under low load, when you are not asking your engine for power.
2 You're not introducing anything harmful to your engine. Anything the EGR system puts in your combustion chamber was in your combustion chamber not 1 seconds ago.
3 The EGR system lowers combustion temperature while simultaneously reducing fuel consumption. To put it briefly, if a portion of your cylinder's volume is filled with exhaust, the MAF will detect a reduction of oxygen flow, and the ECU, knowing the EGR is open will advanced your spark and squirt less fuel. Result = less combustion = lower temperature and added efficiency as a benefit.
4 You will reduce your power output. Let's say you do 3 highway pulls with a brief rest of coast/cruise in between each. Your EGR system would have opened during your low load situation, cooling your cylinders as described in point #3. Except now its not! Each successive pull will be slower and hotter.
Exactly. Efficiency is also lost due to higher pumping loss without an egr during low load situations.
And if your combustion chamber is dirty, some cars can even experience light knocking due to much higher combustion chamber temperature.
Yeah…. Except diesels combust fuel using compression! Not spark ignition 😂
Can you leave the EGR in place and just map it out ?
Potentially yes :) provided you could find someone to do it 😂
No you can’t
@@ethancharlton4626 why not
a good tuner can map it so the EGR stays SHUT at all times essentially the same as a blanking plate the gasses hit a wall and can't go back through the engine, Jason at BWChiptune near London or Stan from Ecotune in Glassgow can do it for sure, I'm not sure about other reputable mappers though
YES YOU CAN.
for everyone who want to do egr delete you should also remove dpf and snap on downpipe, because you're dpf would get clog over time and you will lose power

Mr330d what about when he uses a emissions detector to see how much is coming out and it’s higher than it should be? I mean the tool they put in the tail and hooked up to computer
mrjb7789 I know what you mean but however in Northern Ireland anyway Only petrol cars and lorries/busses get emissions tested don’t ask why diesel cars don’t because a lot of young chavs are driving around with “smoke maps” installed 😂 that look like total shit In England Do Diesel private vehicles get emissions tested ? 🤔
Mr330d surprised they don’t to be honest, they do in England at least, brought in new rules and stricter tests, probs because light of the VW emissions scandal. In the MOT here if they see any bit of smoke it’s a fail before they even put the sensor in the tailpipe
some chiptuners close the valve permanently in the software.

That is all i have to say on this matter.. Lol
If anyone wants this hackmod doing to their rover 25 TDI.. let me know.. I invented a better setup. And I will explain it to you in this thread..
But remember this-
You HAVE GOT TO use high efficiency coolant, and you MUST let it warm up fully before you thrash it, and you must be mercifull or you will blow it up in seconds..
And no side-steping the clutch either!!
or that gearbox casing is done for!
If you want the trick, just ask nicely..
You might want a second turbo..
I was to scared to push it. Past 20psi..
But after seeing how far you can push a 1.0l ford fiesta, (190bhp)
I wish I had gone harder!
It should only operate below 1500 rpm. The problem is short journeys and stop start traffic. Only get a diesel if your regular driving is more than 10 miles and you can get over 40 mph. Anything slower or shorter doesnt let the exhaust get hot enough to not have carbon build up.
Saying that, the attempt to reduce pollution by making you have to clean it out anyway is rather stupid.
Don't worry it's only the air we all have to breathe.
The jet travelling world leaders think that too……😏
Is it ok to delete the EGR and leave the DPF on the car?
Your DPF will clog up over time
I can understand why people do delete the egr and remap it because it costs to much to replace the EGR. Now if the EGR is blocked up with carbon so doesn’t function then why are the vehicle manufacturers doing something about it to stop the EGR from blocking up in the first place. But yet the DPF gets rid of carbon by doing a reg but yet the rest of the engine gets clogged up so one problem is solved and moved to another area . Tomorrow I am having my EGR deleted and stage 1 remap done on my Vw passat 2013 2.0tdi because my EGR is on its way out and will cost £1100 to replace, my car has just done over 56k so in another 56k I’ll be spending another 56k on top of what ever else blocks up in the engine with carbon
So you pay for the vehicle with EGR technology that reduces pollution but still get taxed using a complicated Nx scale system….🥴
Oh yea...the ultimate TRUTH...just remove the freakin egr
and DPF
The video says delete the egr?
i have egr delite kit on my golf mk4 and in my conty only thing that police is checking is disel fuel so im kinda safe but i have all original parts in my trunk bsc once per year on local car examination they make emission test so i put egr back on engine
How much is the cost for egr and dpf delete, total cost
Took mine off 2 years ago. Still flew through mot. Fuck it
I Have audi a4 2.5 tdi 2003 (Automatic-DSG)
it is more better to do EGR off ?
or
To Clean it and to keep on my Car Please Tell me ?
Can be deleted with software. Cost around 300 pounds.
How does it make sense to lower emission with something that increases the amount of fuel used and increases the chances of you engine failing. What a joke.
Can anyone send me link to this egr delete kit please I have the same engine as in the vid
Buying diesel cars arent worth it in the long run if not used mainly on motorway !! Egr and dpf are a pain in the ass
And I was contemplating about an egr delete on my 2010 Avensis..I just don’t like the idea of walking home if I get stopped..but question..can the DVSa dismantle the egr to see if it has been blanked..
We bought a vauxhall astra 2008 last November but it didn't have the egr valve, it's not missed a beat. We are going threw oil though, I've been told that it's not essential to have it on for a working car (forget that you need it for a mot) thoughts?
Hey Ally!
You do technically need it for an MOT but the chances of a mechanic noticing it is gone or even caring that it has gone is very slim! cars generally benefit from having it removed! in terms of your oil consumption it could be a number of things so it is often worth taking a look at the forums to work it out 😁
Thank you driveline ❤️🍻
Esentially
the good thing is that egr makes the engine heat up quickly in the mornings.
I totally agree. I deleted mine on a 2006 Seat Ibiza 1.9 tdi FR and had it mapped out. With hindsight I should have just cleaned it properly and put it back on.
@@88CBAUGH has it been passing mot emission test since it was done ?
Yeah mine stalls on cold mornings
Can it damage the engine? Asking for w204n mercedes
Hi mate what happens if it all gets clogged up? Is it expensive to sort if it happens?
I don't have the answer to this, but your question raises an idea. If the EGR system clogs up it's essentially not recirculating gases and essentially self deleted. However you may need to clean the intake passages carefully not unplugging the EGR passage. haha.. If anyone asks about your EGR, I guess it's plugged.. doh!
Can you just clean it and leave it there but remove off ecu. Will that be fine? Just to take it off ecu but just clean and leave it. Would I have any problems?
If it's a single entry port put the blanking plate in and put the valve back over top so it looks like the valve is in situ and working. Have it deleted from the ECU and voila. VOSA or whoever's only do a visual check.
So I've decided ile leave my egr in the boot 😂
Is it a good choice to delete it?
This is just all reasons to have the 2A.
