EGR Blanking + EGR Cooler Delete on Audi A3 2.0 TDi
HTML-код
- Опубликовано: 29 сен 2024
- This is a process for blanking the EGR valve and deleting the EGR cooler on an Audi A3 with a 2.0 TDi PD engine (BKD 140)
The reason for blanking was that the entire EGR system was clogging up the intake, as well as restricting the airflow. Despite being flushed and cleaned multiple times it was still throwing faults on the dashboard so I had it blanked out and ECU reprogrammed. No bother since.
I imagine the process will be similar on most VAG vehicles (Volkswagen, Seat, Škoda and Audi) with a PD engine.
⚠️Please bear in mind that EGR is a part of a vehicle's emission control system and depending on your country its removal could cause your car to fail emissions test.
Q: Is it necessary to remove the cooler as well?
A: No, it is not necessary. I removed mine as it was faulty and leaking coolant. If you choose to keep yours, make sure you fit both blanking plates at the same connections as shown to maintain neutral gas pressure in the cooler- if you only fit one blanking plate at EGR valve, the gasses from the exhaust manifold could cause a high pressure buildup within the cooler and it is not good.
Thanks for this. I don't have any leaks so I plan to retain the cooler, & leave all pipes in place. I hope that's right?
@@philmcfadden yes, it is absolutely no problem, the coolant will circulate through as normal.
Thats great video dude but are you not fail the MOT whit this EGR delete?
@@Adam_G 1. First the positive pole is connected, then the negative pole. When removing the battery, first disconnect the negative pole. Otherwise there could be a short circuit and your entire vehicle electrical system is broken
2. Do not pull the poles so hard with a large wrench that the poles bend.
@Adam G. After 2 years have you had any issues after the egr delete?
Very useful information, thanks.
honestly man I cant thank you enough for drawing that diagram super simplistic and straightforwad
Any problem in long run for engine
Can you Show us how you delete the egr from ecu ?
Unfortunately I had to find a mechanic with a tuning computer and it's simply not something I was able to do myself
Quello è motore Iniettore pompa okk ma per i CR come si interviene
Hey Adam. Can I just check the other 2 small cooler pipes just need joined together yeah ? Cheers 🍻
Yep, they need connected so that the coolant can cycle through as normal 👍🏽
@@Adam_G cheers Adam on my Octavia mk2, 1 of the 2 small pipes can unclip from the engine and the other can go in it’s place to bypass the cooler. I was just checking. Thanks for taking the time to reply. And thanks fir doing your vid pal 👍
Bonjour au voyont moteur réfus au
contrôle teccnique
I blanked my egr an got eml 🤣 does this have to be mapped out or will a code clear do the job?
well you need to map out egr from ecu to remove eml
@@furumux thankyou
Why an EGR is removed ?
Due to a fault. It often clogs up with carbon and creates problems
@@Adam_G
Can De-carbon spray cans help ?
@@omercoolbuddy I've fully disassembled the entire system to clean it twice but still had problems
Can I just blank the egr of without blanking it at the cooler end and then remap it out
Yes, if your cooler is in a working shape you do not need to delete it. Just blank it at the exhaust manifold and intake manifold flanges.
@@Adam_G thanks mate if I got a remap with egr delete would I still need to blank it aswell
@@vfn112 depends on who you ask really but the blanking kit is a mere couple of quid and it just makes sure the entire system stays stable- no gas in, no gas out. In my opinion it's best to blank it.
One of the very few people on here that actually know in depth what they are talking about
Yes blanks 2 of them same pipe
My kit came with a temp sensor thing. Where does it go🤣🤣🤣
I used this delete on my Passat PD 140 - instead of using the brass 90 degree pipe you can use a straight clip on pipe to replace the original angled one - part number 3B0122291C the original rear rubber pipe fits directly on and looks factory. Another good idea is map out the EGR from the ECU and at the same time delete the swirl flaps, you can buy a non swirl inlet manifold also map this out with a stage 1 but get a decent tuner who knows what they're doing!
Thanks for the info! The PD140 engine is identical to mine- the EGR got tuned out eventually
The swirl flap prevents a runaway scenario. Best not to remove that.
@@fearofchickeHaving had 4 of these in the past & still owning a MK5 Golf as my daily, I can safely say that the swirl flap doesn't prevent a runaway scenario, even when it's working correctly.
Even though it was thought with that intention...
And everyone should know what to do in a runaway situation, shouldn't be hoping for a swirl flap to save the day.
I have a 2018 audi a6 2.0 TDI, i am about to delete egr ! Is it right thing to do ? What do you guys think?
Thank you so much man for this awesome video. I need to a dpf delete to my golf tdi as well. I wish you could do the same thing for PDF.
Whare are you located? Do you have a shop in Columbus ohio ?
Glad to be of help! Located in Ireland so it'll be a long drive 😁
just looking at this now
ive got the delete kit and wondering what size plates are required for the cooler as mine came with one.
ill be removing the whole set but want to know if i need more blanking plates and sizes before i start taking it apart
Hi friend, look I have bought a new engine, because the last engine broke due to the egr gas cooler ... you recommend
bypass the egr valve electronically and bypass the gas cooler as you said?
Is there something going on throughout the life of the engine?
Hi, the entire egr system tends to clog up with soot and carbon over its life which is normal. The system needs cleaned regularly but only in the most extreme cases the egr may damage the engine. If you remove it the car may no longer comply with emissions standards but it takes out one thing that could potentially break and cause trouble.
@@Adam_G
It is that my last engine has been broken by the gas cooler, so I bought a new engine, and I am afraid that the same will happen to me.
Do you recommend deactivating gas cooler?
Is the vehicle better without it?
have you tried it What is your experience after removing it?
Your video is extremely clear and informative, thanks. And your patience in the comments, answering the same question a million times deserves a medal lol. I'm about to do the same to a 2013 Seat Leon 2.0 TDI (leaving the cooler in place), gut the dpf too, upgrade the air intake and get it mapped to suit. So thanks for the clear instructions in the video 👍
No worries at all, thanks for the positive feedback and wish you luck with your project!
I live in a state where emission testing is non-existent. Time to do this hahaha
Excellent video. I did this procedure about a week ago. I still don't have an engine light or even a fault on VCDS (EDC16U1, BKD engine, pneumatically controlled EGR)... The car is reprogrammed but in checking on WinOLS5 the EGR hysteresis is still present... I don't understand but I'm not going to complain :)
Glad it's worked out better for you!
hello awesome!
I have a golf 5 tdi 140 bkd injector pump and I think I have suddenly ke even egr sue you
what are the references of the plates when you put or can you give a link to order please as well as the diameter of the tube for the coolant
thank you 👍
Conseguiu achar e em qual site ?
Do you have check engine light after this? How to decode the EGR from the compute to avoid check engine light?
I did indeed, my friend coded it out using a remap computer
Dude you are the best!!!! I own a MK6 Golf TDI and was confused because I didn’t believe it was that easy and it sure was! I appreciate the best explanation in this video!!!
do I think it's a good idea it's not necessary and you have to make sure you don't block the breather pipe from the oil to the top of the engine if it's going through the system that always has to be connected to the rocker cover
do nothing put sealant in like that all it's going to do is block up your catalytic converter. get some handmade gasket material and it's heat resistant make your own gasket
hello Adam good tutorial, my car breaks the small pipe of the cooler it seems that it takes a lot of pressure until the pipe is cracked (I have already changed it twice), it could be a failure of the cooler that is plugged or that does not open and that is why it breaks Why don't you let the pressure pass? thank you
have you found the answer yet ?
Buy a EGR delete kit - it gets rid of that metal pipe. Blank off the the cooler .
Found that getting rid of the pipe made the thin blanking plate warp with exhaust pressure and leak gas, so I ended up reusing the cut off pipe flange to clamp the plate onto the cooler.
Did you get leaks on the exhaust blanking plate as it looked a bit thin? Guess it was ment to be put in between the cooler intake and the exhaust?
I actually did a week or so after uploading. What I ended up doing was cutting off the cooler flange and fixing it on the top of blanking plate to prevent it from warping. These thin plates indeed were made to be placed between two thicker bits of metal
Thanks for the video! Where did you get your blanking plates from?
Always glad to help! This kit was ordered from eBay
@@Adam_G thanks mate!! I was just taking mine off to clean it, but one of the allen bolts is completely rounded
Thank you so much I was really worried this was going to be hard but you explain everything so well 🙏
Is it difficult to remove the cooler mate I've just bought the kit and the brass L piece hoping to do this soon
Was it hard?
Hi
I was wondering if I'll remove the dpf filter, my car will still pass the MOT test or not.
Thanks!
Really depends on the tester but according to the law and testing guidelines, a clearly missing dpf is a failure. Some guys buy faulty dpfs and remove the insides of the actual filter, making it straight-through.
😊😊
Great explanation, thank you)
grzie mille del tuo video,peccato che sei lontano altrimenti te la facevo eliminare anche sulla mia auto....ce qualche meccanico di fare lo stesso procedimento nei dintorni della campania??
Excellent content great effects can this be done to a 2010 Vw golf mk6 2.0 tdi engine
Absolutely, it'll be very straightforward as your engine will be near identical to my one in this video 👍🏽
Guys, any tips would be helpful, I have a remapped Audi A4 B7 1.9 TDI Sedan from 115 to 145 hp, but I have a laggy turbo and reduced power, checked all vacuum lines, tandem pump replaced, new intercooler as well, MAP and MAF sensor, new turbo, anyway, let's get straight to the point of my question... I have blanked my EGR on the exhaust and at the EGR valve, but I did NOT put any sealant or silicone on the plate on the exhaust, so could it be causing the exhaust gasses to escape and lose the pressure so it cannot spool the turbo the way it should?
Either a gasket or some form of seal is recommended as I even had to reinforce my original blanking plates due to pressure blowing out the sealant! Fully could be the issue

How did you get rid of the check engine light? Its necessary to remap the ecu for that? Thanks and greetings from Argentina!
Hi, yes, to get rid of the light you must remap the egr out of the ecu. Best of luck!
@@Adam_G Thank you so much. Good luck :D
Quick question. I got a BKD aswell, and since i blocked off my EGR I noticed NO fault codes or anything? Do you perhaps know if its possible that the first generations of the 2.0 TDI PD did not monitor EGR? (my car also does not come with a DPF from factory)
Hi, there's a chance the EGR was already programmed out, otherwise the ECU normally throws a fault when insufficient flow is detected
Am I able to leave the egr cooler in place but disconnect the exhaust manifold to cooler tube and block the manifold?
Thanks for this video mate!
Привет, Ты менял программное обеспечение, или оставил всё как есть?
После этого проекта ездил как и прежде, только горела лампочка на панели, попросил друга, у которого был Фольксвагенский компьютер, чтобы убрал ЕГР из системы. А в прочем само вождение не поменялось- движок работал как и перед кодированием
A random question. could you possibly get more power/clean air into the engine if you was to somehow link the EGR intake to the air box? or a custom air intake with the cooler providing some type of 'cold air' thing? If done right...could that be done?
no and no
Never hurts to ask questions like that. That is how new things are engineered. Its innovative.
The egr is used when you don't need power, so cruising along at a steady speed, some exhaust is pumped in to save fuel.
When you accelerate, the egr is shut off as you need clean combustion to produce power
@@davidoff59 uhhh no. The egr is for reducing oxides of nitrogen or NOS emissions. That is it. It actually causes the vehicle to consume more fuel but burn less
Great. Thanks for your tutorial
But the vacuum tube of the auger will return to its place after deletion ❤
Great video mate! Very informative - wish I had of gone to as much effort as you have! - I've made a video on how to remap out your EGR at home
Hi there. Do you have a link of your video for deleting /mapping out the EGR??
@@gavinfisher8049 yup - it's on my channel
Great video,but if i only blank the exhaust gas outlet from the manifold,and keep the all system including the vacum line to the egr valve,do i get a check engine light?because by doing so,the system will operate normally,there just won't be any exhaust gas flow through the system.
Thank you very much
Correct, you'll have a check engine light as EGR will measure zero flow, however the engine should function as normal
A dumb question coming up: why do you do this? What is the purpose? I know little to nothing about engines, more than that I need to replace my EGR valve somehow haha
Some people do it for tuning purposes, it's one of the steps. You get only clean outside air into the engine, no recirculated exhaust. You 100% need to modify ECU map for this to be 100% legit.
Others do it because the EGR Cooler (the one in the back of the engine) is very expensive when it goes bad. Maybe for you 400-500 eur for the EGR cooler is ok, but these cars are getting old and cheap.
Hey so with leaving egr in place and just removing return pipe and cooler you don’t need to map egr out? Cause I was thinking on removing mine but egr also but need to map out so eml doesn’t stay on.
If you are blocking the gas flow the computer will automatically detect not enough gas is going to the egr and it will throw a fault. Which means you are best to code it out, but you can drive the car with eml on no problem.
But if EML is triggered it may take engine into limp mode with limited rpm and performance.

@@Adam_G no thanks
Good video mate well done. I'm about to remove and clean the cooler and valve on my bkd 2.0tdi before I sell it. Its got a lack of egr flow fault and I've already replaced the egr valve before the asv.
Glad it helped! The soot buildup often clogs the air passages over time which throws all sorts of faults. All the best
Hi Adam! I just bought an Audi 2.0TDI Quattro 2015 model, and was wondering where the EGR valve is. Is it in the same location as your car ? :O
Hi, congrats! The 2015 is most likely the CR engine- look out for the big metal pipe running around the engine from intake to exhaust, it'll lead you to EGR!
How manny hp? Is it get whit a blend egr?
Was your car in limp mode till you got it deleted?
No, only the check engine light. The plates were bought from eBay.
Fantastic video help me alot cheers do u have a link where u got the plates cheers
how turn off check engine after blanking egr?
Bravoooo
Hey - I have a 08 golf tdi 170 will this work on mine too? Just two blanking plates and the 90 degree pipe to connect inlet/outlet
Hi, should be good as the block is pretty much identical. These blanking plates work for the vast majority of TDi engine EGR flanges.
Io ho lasciato il radiatore della egr è meglio toglierlo grazie
What fitting do u use for conecting the pipes from egr cooler?
Can i blank the egr and cooler off but leave it all in position? And leave the coolant hoses connected to cooler. Just so the MOT tester doesn't know its been tampered with.
Yes
What you think if I leave egr cooler inside, just blanking it and removing pipe, is there any downside to that?
Absolutely no downside if your cooler is working as it should (mine leaked). The coolant will simply circulate around it and return to the main system- and it's fine to leave it as it is.
So I should put blanking plate just before cooler, right?
Also can I keep the pipe in that case with just installing blanking plates on each side?
@@dariolinoo the exhaust blanking plate goes between the manifold outlet and the cooler inlet, yes. And since no gas is entering the cooler, the pipe can stay (provided you also blank the intake side)
Those two plates are not same size, are they?
@@dariolinoo for me they were, as Audi used identical-sized flanges for the entire system.
Fantastic video! Thanks!
dont know why i watched that because i have no clue what it does haha
Banging vid. Any leaks as of yet?
Appreciate! No, no coolant leaks. Had a small exhaust flange leak but that was due to me applying the exhaust paste wrong, all sorted and working well now.
@@Adam_G Hello, and what was wrong with than exhaust paste?
@@Rimlax123 Hi! Due to heat and pressure from exhaust gasses the blanking plate would bend and create a small gap through which the exhaust paste would blow out. I fixed this by cutting off the original cooler flange and fitting it on the top of the blanking plate to keep it fully flat and firmly pressed.
Adam G thanks's Adam
Thank you so much sir
Greeting.
Does removing or blanking the EGR affect the operation of the particulate filter? Will it clog quickly?
I was thinking of doing the same with the EGR as you, but leaving the DPF until it starts causing problems.
Passat b7 2.0 TDI 125kw 2012.
Thanks for the reply, cheers!
Hi, the DPF shouldn't be affected to my knowledge, especially if you use the car on longer journeys where the DPF has an opportunity to regenerate. Speaking purely theoretically as my A3 was '06 and was not equipped with one
@@Adam_G thnx for replay, cheers! :)
Ciao io ho una Audi A4 ho eliminato l'egr volevo chiederti il radiatore raffreddamento collettori di aspirazione devo levarlo grazie mille
Hi Adam,
Would I need to blank off the EGR cooler side as well as the valve side if keeping the cooler? Thanks
Hi, ideally yes, this will prevent pressure buildup from either side of the cooler
For what purpose should I blank my EGR on SEAT Toledo MKII BCB motor / same as GOLF 4 / Skoda Fabia
If you have a check engine light, fault codes with EGR, rough idle or abnormally low power
What happens if I don't map the EGR out of the ECU? Will I have problem with the engine or just a engine light on dashboard?
Just a check engine light really
Hi mate do you have to blank it off from both sides. What happens if you only block the front one by the radiator.
Hi, you're risking an internal pressure buildup, hence blocking off at both ends.
I assume this can be done on an Audi a4 fsi?
How much of an affect does it have on an emissions test? Thanjs
If your emissions tests NOx, that's the harmful bit that EGR reduces
Will this give any gault codes?
EGR insufficient flow accompanied by check engine light, unless programmed out by a mechanic (usually no more than couple hundred euros/pounds)
What size is the blanking plate or where you can get it I'm trying to do the same on a 2.0tdi Audi 07 no dpf
Hi mate, search for a "TDi blanking plate" on eBay, the egr flanges are all standard size so the same plate that fits an A3 will fit a Q7, A6, Passat, Leon etc.
Hi mate you don't know a size for the small lines do you? Do you have to buy a tee piece for them?
Small ones were 8mm? If I remember correctly. Could be 10mm. They slide off a metal sleeve and you can conect the other rubber tube to the metal sleeve and create a loop.
I have pressure (bubbles in coolant system) when engine is hot. But I don't have white smoke from exhaust on first start or anytime in long drive. It is losing water little bit from cooling system. What can be problem? Car is golf plus 2.0 TDI 2005 16V BKD
Did you solve problem? I have the same problem. When I start the engine while it is hot, it smokes white smoke for a short while. 2008 2.0 bkd jetta
@@mustafakayakiran8696 yes i solve it. I sell the car :-)
Hi.Egr blanking serial number?Thanks
Salve Adam una informazione dopo che si fa questa modifica, rimane la spia accesa di errore ??
Ciao, that's correct, you'll have a check engine light

How do you know which vacuum line is for the cooler without removing the cooler? More specifically, how do you block the hose connection on the cooler if leaving the cooler in place?
Hi mate have you got any way I can contact you , I need to send you a picture of a egr if you can help
Shoot me an email, it's on the About page of my channel mate

Hi , can you link the L piece connector please or tell me what size it is , thanks
He told you what size it was in the video. Listen again
Hi, do you have a link where I can buy the blanking plates? Thanks
Hi sorry no link but simply search “2.0TDi EGR blanking plates” it’s a universal design for all engines really
Will have to tune it afterwards?
Brilliant video mate I've got the mk5 golf pd140 and my engine light is on and it says emissions workshop. So if I delete the egr will the light go off? Also with the light and msg coming on am I right in thinking the egr unit is nackad so would I have to change that? And if I did change that would the light go off? Thanks mate
Hi, you’ve same engine as myself. If you remove the EGR the light will stay on as the engine sensors will receive data they don’t expect (zero flow etc) though the car will drive fine. If you want to get rid of the light and warning you should get it mapped out of the ECU
@@Adam_G hi thanks mate I changed the egr and I'm wondering what did u do with the lil vacuum pipe?

Hi is this a fix for error P0401 Exhaust Gas Recirculation (EGR) Flow Insufficient Detected? If not, anyone able to advice what I should do? I have an AUDI A3 2.0 tdi 2005.
Hi, this was the exact fault I dealt with. I tried cleaning the entire system with no luck and was only able to get rid of it by blanking the EGR and deleting it from ECU.
@@Adam_G How do I delete it from ECU. I have VCDS
@@japforce11 I have VCDS also, unfortunately it can only be used to change settings and read data. My tuner used Kess V2 computer to do the job.
@@Adam_G Thank You very much
Is this the same engine as a 2012 mk6 2.0 golf tdi?
Hi, not same but similar- the primary difference being injection pump in older TDi's vs common rail in newer ones
I must block the egr cooler too?
Or its ok to blank only the valve?
Not necessarily, blocking the EGR only is fine
The best set up i have been able to do/experience without spending any money is 1. swirl flap left in 100% open position by removing the swirl flap actuator arm from the body. 2. EGR fitted with restrictor plate or if due to MAF sensing /too much air coming in the air intake the EGR is stuck in closed position 😁.This set up is reversible at any time in a matter of 15 minutes and yields no black smoke, lowest diesel consumption i have experienced and increase power in all revs.😁 plus if u manage to drill thru the whole DPF its even better as u will never have backflow or airflow restriction in your exhaust system which cause the famous coke up of your engine and air intake.With these set up, you will drive your engine around with no diesel/soot smell from your exhaust which will avoid people from complaining and such.
Thanks for the suggestion! I'm running a smokeless setup at the moment too with blanking it out.
Hi I’ve recently bought a 58 plate Audi A3 Tdi. It’s having a problem with loosing coolant. There is no mixing of oil and coolant and no visual leaks of coolant. I am yet to pressure test for leaks. Who ever owner the car previously has bypassed the egr by simply adding a piece of pipe between the two hoses like you did at 5:30. So the egr is still fitted just bypassed. Is it at all possible that this is causing problems with the coolant and loosing coolant from there. After reading this out loud I think I may be wrong but any help would be greatly appreciated. Many thanks
There are two sets of coolant lines going to the cooler- the primaries (ones I bypassed at 5:30) and secondaries, the thinner ones. It's possible the coolant could either leak into the cooler via the secondary lines and then get sucked in with the intake air and burned up, or in the worst case scenario, enter the cylinder via a bad head gasket. If your car is idling and you open the coolant reservoir and it's bubbling, it's most likely the head gasket, if not, could be the cooler.
Adam G Adam G hiya mate thank you for replying. I realised after commenting I was a bit mistaken. So the egr is still fitted and hasn’t been touched, the cooler is also fitted aswell however that is what has been bypassed (by the thick pipes at 5:30) the coolant doesn’t seek to bubble and doesn’t seem to be mixing into the oil, so to me that says is not the head gasket. Could you advise me please what next step you would take. Thank you again for your help
@@JLOOOOOOOOOOO do you know if your egr has been mapped out? If so, since the cooler is bypassed, you could get rid of it altogether and put the blanking plates in. If it's not mapped out, it leads me to think the previous owner suspected a leak and done some tinkering. How often does the coolant need topping up?
Adam G not too sure if it’s been mapped out tbh, bought it quite cheap with not a lot of information. I’ve just realised aswell I forogt to mention in my original comment my engine is slightly different to this it is a 1.9 TDI if that makes much difference? It’s abit strange the coolant seems the be abit hit and miss. Sometimes it goes down very slowly and needs topping up just a tiny bit. Other times like one Saturday, the coolant light comes on then when I checked it the expansion tank was completely dry and it took about 2 litres if not more.
I have just brought 2 blanking plates as i wanna blank mine off so can i just leave the cooler pipe on but put the blanking plates behind each end.
Correct, you can simply blank off the EGR at pipe flanges
@@Adam_G brill cheers mate
@@dans9152 all the best with the job 👍🏼
Don't quite catch on 5:45, what is that secondary cooling lines?
My engine has two pairs of cooler lines going to the EGR cooler- two large main hoses and two small ones. Not sure of their exact application
Adam if block the egr valve it wont harm the turbocharger destroying it sooner than normal?
Hi, the turbo pressure will be unchanged so it should serve as normal. Just make sure to regularly change your oil :)
@@Adam_G Big thank you !
