- this is the eziest DIY you can do that will actually help Diagnose your car. This DIY eliminates all the headache for looking for boost and vacuum leaks.
To get the Resistor kit order from
www.urotuning.com
I also suggest to order the blockoff plate from them as well or make one from sheet metal which cost a lot less.
I also suggest to research your local and state laws for modifying your SMOG system.
Basic hand tools and allen wrenches are needed for this JOB.
This is the link to the kit you will still need to buy a block off plate for the egr/combi valve or make one.
www.urotuning.com/Basic-Parts-Kit-for-SAI-N249-PCV-EVAP-Delete-p/sai_delete_parts.htm
what does the SAI block off plate do?
it cover the small exhaust port on the side of the head where the combi valve covers it.
PincheALs Garage , when you do that job the light of the check engine doesn't turn on ? it doesn't affect when you do the smoke check ?
the chekengin no start in my gti no start an pass de inspection no problen the problen is the boost controler no worck
what hose line did you use to route it to the break boost & the diverter valve? did you reuse hose's?
Currently doing this to my MK4 GTI! Just ordered kit off of Urotuning! I cant wait to have my car running again! Yeeeeee!
Currently reverting the delete. Might need some assistance lol. Thanks Alviz for hooking me up with the parts! Much Love.
Great dyi! I did this almost 2 years ago and did it right the first try! Thanks pincheAL.. Forgot to give u props.
Thanks for doing this DIY man. It's something I've been wanting to do to the GTI for a while now and this has helped out a lot.
your welcome. I have a ton more DIYs coming. Just going to postpone them after car show season.
Hey man I subbed due to the detail you go into!! Very awesome I have the block off plate just have to get the resistors. I'm doing a delete and a catch can all in one go and hopefully in the process figure out why my motor won't go above 5500 rpm and I have no speedometer 04 1.8t AWP
dude i died when i herd the music😂
8bit banger 😆
i love how your just giving your homie a tutorial while giving the camera a tutorial lmao
U got me at smog system delete :) keep it up .....new sub
Bad fucking ass diy! Love this channel
thanks man!
The open connector by the 2 resistor connections under the intake manifold - that just stays open/disconnected? Thanks!
@PincheAls Garage - Ive done all of what you guys done on this video. I have a couple of questions. The first vacuum valve from the SMOG filter thingy, not the manifold side, the one next to the coolant reservoir ... u dont seem to mention if it needs to be capped off? or left alone with no pipe on it now? secondly ... i yanked the brake assist pipe at the rubber/plastic valve near the bulkhead, instead of cutting it like you said. there was a loud pssssss .... can i just reconnect it as if nothing happened lol!
You’re the man. I appreciate this video so much
I know this topic has been beat to death, but I have a quick question. Would it be possible to remove the combi and the n112 but keep the N249? or is it better to just remove it all and run the dv to the manifold?
Hey man, thanks for the video it's a big help. I've got a kinda stupid question though. My stage 2 tune has sai and such deleted already. Will I still need to use the resistors or does having it tuned out take care of that? Thanks!
Wondering the same thing
What check valve would you recommend using? I installed this kit onto my jetta. My boost is stuttering
Can I just delete the the left side if I dnt have the resistors and the plate to cover where the combo valve is
Hey bud the metal lines that have the rubber hoses you cut do you need to cap those lines?
Great DIY. Do you have recommendations to get rid of the CEL due to lacking the SAI? Can that be done with the VCDS?
Get a tune
That is the best wat to get rid of the CEL
Please, please, please, could you tell me what the music is at the end? I remember listening to it once when I was younger, so memories flooded me when I heard the tune. Thanks.
Song Of Storms Dubstep Remix - Ephixa ... this one?
i thought it was Contra... thanks
Do i need to purchase the kit or can you do this with out the kit and resistors? My tune has the evap and sai delete on it and i beleive i also have the 2nd o2 sensor deleted as well
PincheALs Garage, Im confused on what you did with the breather tube elbow coming off the top of the oil cooler housing.
Awesome DIY man. Do you have any pics of how your combi delete plate came out??
No sorry it was such a long time ago
PincheAls Garage ok! Ty for the reply
Thanks for the video always great info. Can you tune the sai pump cel? Thanks
I can not do tunes
@@PincheALsGarage i really didnt mean you bud just asking if it was possible lol
Yes it is possible. Just find a good tuner. I suggest Boost Dynamic Tuning. Ask for Trent Smith and tell him I sent you
@@PincheALsGarage Thanks Bud i appreciate that i will mention you
what is the size the hoses i need to change ..
thnk u sir..
ok si yo elimino mas que lasmanguitas que sacaste del blow off le puedo dejar el compresor de aire secundario funcionando o lo tengo que eliminar todo ala ves
Jose Jimenez para que sirve eliminar este sistema y como repercute en el funcionamiento del motor?
What is the second vacuum line under the intake manifold? You took off the left side, what is the right side?
that's for the PCV line
Man oh man this looks scary. Does any kits come with directions?
Nope... I have the best diy so far for this job. I been meaning to update this DIY just need a car that is stock to do it.
You can fly out to NJ to do it on my stock mk4 2005 gti 1.8t. 😂🤣
ive got a 03jetta, a round trip ticket and a lake house in North AR if your still looking for a stock car to do the update oñ)
can you give me the link for the delete kit
What mm are them plugs ??
hey what coil setup you have?
On this car we have Raceland Ultimos
yo ise ese trabajo y el boost controler me dejo de trabajar porque que ise mal
what did you use to block the pcv unit?like the one that connects to the air intake?
we looked for a bolt big enough to cover the hole. the short hose that comes off the intake and pushed a bolt right in and done.
Just saw this. Is there something like this for the Vr6 12v?
Coming soon
What size hose do you use for the brake booster line?
i just took the hose to autozone and matched it up. 2 to 3 ft should be long enough.
1/2in line
So what's the reason I would want to do this ? Will this increase my horse power? Or?? Idk I'm confused 😐
Steelo phama justto cleanup your engine bay
Also if you have any idea of why my speedometer and rpms are doing that it would be helpful to have a different point of view on it
You need to checker your wires make sure they are not frayed, ripped or oxidized. Also you might have a failing sensor so that would be the last thing to replace if all else fails
I have checked my wires and they look good it's quite annoying
Does this cause a sharper torque spike or no? I’ve been told yeah and no from different tuner shops so idk lol
No that depends on your N75 aka waste gate solinoid. Your tuner or tune control's the N75 which will regulate your wastgate
PincheAls Garage ok, I have a stage 2 tune from eurocustoms but I didn’t do the evap and SAI delete on it. If I were to do this what issues could I run into?
Hey nice video I have my mk4 apr stage 3 plus GTI we are doing this delete. But have been hanging my head trying to find a software delete for the cel after . Apr use to do it for stage 3 plus but they don't anymore . Anyone know if any place. I don't need a time I have aprs full time already just want to delete the emissions software
Most places that tune will need to reflash your ECU
So your issue might be that you might lose your APR tune or they wont do it without saving the tune.... In all honesty i dont know. Never have had this issue. I would personally suggest a new tune with all the features you want but get a new ECU that way you dont lose your tune. If you dont like the new tune go back to your old one. Simple or you do like it you can sell your APR tune make some $$$ back.
Thanks for the reply I ran into that couple places wanted to do a new tune . I just don't want any other company other than Apr . They stopped doing the delete after the TDI lawsuit. My GTI is full Apr from intake manifold to stage 3 plus turbo and intercooler right through everything else . The only thing just that isn't is my carbanio cold air intake. But I do appreciate your help thank you
Will it pass emissions in any state?
Will not pass emissions in States the require testing
@@PincheALsGarage What's the minimum we'd need to reinstall to pass emissions? Shall I reinstall and connect my air pump? I just need two emission control systems to pass. I already got the catalytic converter passing.
If I remove SAI do the I need a resistor or will it just throw a code that does not affect my car?
Will cause performance issues. You will NEED a tune or a Resistor.
@@PincheALsGarage is it one of the same resistors that are on uro tuning
@@Jamez100899 correct get the whole kit so you can do it right.
@@PincheALsGarage Thank you for the fast response I only got the kit with the 3 resistors so I guess I need more lol
@@Jamez100899 no you dont need more. Should be the SAI n80 and n249 resistors. Which is all you need. You will need vacuum caps and clamps though. Also some vacuum lines
So if this will fail your inspection, what shop do you get your smog done at? Or do you just drive you me car unregistered lol. If this comment section is too public I can dm you on ig
My car is now registered out of state because it is getting hard to SMOG cars that are modded in cali
@@PincheALsGarage which state and whats the process like?
I got it registered in Arkansas. I rent a room out their since i do work for family. So i can be a resident and register my car.
@@PincheALsGarage cool! thank you
are all three resistors 10watts 330 ohm?
+Korey Sluyter good question.. I dont know the actual Ohm for these resistors since they came in the kit and they dont mentions the resistance anywhere.
Hey how many vacuum caps i need?And average?1.8T aum
Obito Uchiha 4 caps needed
PincheALs Garage ok thx
you got some great guides of the golf mk4.

andrew wright thanks man. i do my best.
You really are the man I really appreciate everything you are doin from a fellow mk4 owner ...thanks again.
Tim Wolf your welcome!
Nice video, would love to get all this crap off my turbo beetle, but you guys went so fast! All the stuff you guys were pulling out looked kinda scary, but like I said I would love to get all that smog junk off. I guess I'll have to watch over and over and just take it slow!
I know this is an old video but in todays climate I would appreciate it if you referred to them as Alternative Lifestyle Pliers. Thank You.
Lol!
Do you know how I would go about deleting the emission system on my 2.0? I saw a similar video I was looking for but my intake has a line going into it and his didn’t and I’m also a noob
Just Subd absolutely Best Video ever. Thanks man
Your welcome! Glad we could help make sure to get a resistor kit or a tune to get the most out of this project
You really are the man I really appreciate everything you are doin from a fellow mk4 owner ...thanks again.

That cluster of hoses that goes down to the engine below the intake manifold, what did you do with the open lines into the engine.
The smallest tap under your manifold is for your FPR and or Boost gauge, you should definitely have a boost gauge. The tap next to that is for your DV. The bigger tap previously used for your Brake booster is capped off. And the last tap at the end of the manifold you would use to run a new single line for your Brake booster IIRC. All vacuum hoses are either replaced, removed, and when necessary unused ports are capped off. Get a tune that deletes this stuff and you are ready to go.
Missimg is the after effect. Obd ? Codes . Mileage. Performance. When you took out the emissions. Do you have a Performance computer?
The N249 with no signal from the ECU communicates the manifold vacumm to the DV, and when the N249 receives signal from the ECU it communicates the reservoir of vacumm to the DV.
Therefore the presence of the N249 I consider is necessary to have a better reaction in the engine to be able to activate the DV even when there is still boost in the manifold, therefore the overpressure does not force the opening of the N75 and the turbo does not fall from Rpm giving better reaction.
As a conclusion I think removing the N249 engine would have less reaction and unnecessary wear on the turbo
The only thing I see as positive when removing the n249 is less vacuum lines, better appearance
would connecting a line from the DV to the intake manifold solve this?
@@bigjesus4986 yes there are actually dyno tests and lots of research shows if you have a larger turbo and other mods ditch the N249
Is it bad if u don’t fix the air pump? I got a code for it don’t know if it will affect anything
No not really it wont cause any issues
Alright thanks
Is this the same for the age engine. So many pipes tidy after. Good video
@23:19 the square plug with the blue wire where on the harness is that going to? I'm having trouble finding mine
What about that one line you didn’t Near the coolant line
Justin ... did u figure this out? are you meaning the white valve thats just open now with no pipe on it near the coolant tank?
Figured it out once I was doing it thank you
TH-cam algorithm sucks so bad!
Wish i woulda seen this before I went the long way about it. Much love though guys. Stay humble!
Thanks man!
Glad you found us
Is there someone in the Tijuana aréa that can do this kind of work, im looking to get rid of all the junk on my Jetta
Awesome video! Very informative, only one question, any materials that need to be bought before doing the project that don't come in the kit? Basically what I've gathered is have coolant on standby and buy some 1/2 inch tubing for the brake booster, anything else I'm missing before I go and start ripping vacuum lines out of my engine? Also, how well does it run without a tune? As of right now my SAI pump is bad so it misfires under heavy load. Would this be an improvement?
Wow 3 years I hope you figured it out by now dude, I’m in the same boat currently trying to take lines out
Thank you, this’ll be a spring ’20 project. I just have take of vcg on Saturday.
Hello friends!
a query. What do they do when the Check engine light comes on?
Because if you turn it on to detect that the secondary vacuum pump is needed.
It can be turned off with some kind of modification with the software VAG COM?.
tnks. :)
Regards,
Vag com to clear it. Tune.
What Aem intake you have? Thanks for nice video \o/
Sorry i dont remember which intake it was.
Can i do this without removing SAi having vacumm leaks but dont have time or money for the resistor. Thanks for the help. 99 beetle gls 1.8t
Technically you can it will throw a code for flow efficiency but it will not effect the car's performance
...and how are you handling the p01440 code you're getting?
I have a problem I don’t want to delete everything but I broke the nipple on the black box that’s connected to the intake manifold next to the dipstick and have no clue what it’s called
And the hose is constantly sucking air and my boost is everywhere
What's up AL! Will I be able to pass emissions after doing this delete? I have a Mk4 Golf 2.slow.
Alan Ramirez no you will not pass emissions
Hey man, thanks for the video it's a big help. I've got a kinda stupid question though. My stage 2 tune has sai and such deleted already. Will I still need to use the resistors or does having it tuned out take care of that? Thanks!
You wont need the resistors just make sure to leave them unplugged
@@PincheALsGarage awesome thanks so for the reply!
Hey bud, thank you for making this video!!!!!! It does clean up the engine bay and it makes it easier to race and find leaks
Glad I could help you and your very welcome.
So in theory I don’t need the resistors if I don’t care about codes, right? Or is it going to run like complete ass
Yeah it will run like dookie without a tune or resistors
Anybody know if there's a kit for a 24v Vr6?
can someone tell me what this does to the car? is it just to have a cleaner engine bay
prevents 90% òf the notorious vacuum leaks !!!
Holy s#@!, My 1.8t aeb in my b5 has way less vacuum lines than this.
Yeah the AEB is a more simplified engine. I used to have one. The AWP is much better.
I have an agu engine and as far as I understand it has No SAI and I bought a sai delete Kit because i thoght ny car had it. What is there to remove on an agu?
Hey! Did Sai delete, changed 02 sensors and camshaft position sensor, but I'm still getting the code for them P0333,P0411, P0420,P0343, also getting smoke outta exhaust and oil dipstick I got a 2003 gti 1.8t any ideas what it could be ? Please Help! 🙏🙏
I love the way you say Lefty Lucccy, hahahaha
so i dint took out the combi valve but i did block it where that extra exhaust go?? i did it in my audi a4
nice. does it work well
Hey man I know it’s a old video but im doing this delete once the kit comes in. Right now the previous owner ran a line from the fpr to a t connector. Then ran a line from the nipple you put the dv hose on to the t connector. And then a hose going to the boost gauge. If I’m running the dv line to the end nipple on the intake manifold where would I put the line for the fpr ? And would I just have to Put a T connector in between the line for the FPR and intake manifold to run the boost gauge ? (Guy I got the car from is a complete idiot so I’m going over all the “work” he’s done to it and getting everything right slowly but surely. Making it easier to find a leak I’m having to where I’m only peaking15lbs instead of 22
Did you clear your engine light if is how ?
Love this DIY, Just onee question. What size is the line that goes from the DV to intake? thanks
from the charge pipe its 3/4 to 1"
to the intake is 3/4"
the vacuum line to the manifold is 10mm
So the dv line is 3/4" or 10mm diameter on the inside?
no those are 3 separate lines
hey i just uploaded a quick video for you about your question. hope it helps
Appreciate it man, love this channel.
Cheers for the video very useful and easy to follow really appreciate it thank you
Your welcome!
Hey man love the video! What size is that hose for the brake booster? Also where can I buy the blanking plate for the combi valve? Your removal shows 3 holes and all I can find is SAI blanking plates with 2 holes. I have an AGU engine and they have no SAI so I'm a bit confused. Happy to donate to your channel once I sort this also I see you mention this in a recent video 🤙🏻
Grant Mac Dee you only need to 2 holes to cover it.
5/8 i think is the hose size youll nseed. just in case just take a piece of the one you removed to size it.
If you get the opportunity to do a PCV simplification video on an AGU as the setup is pretty different. We have vacuum pipes also on the active charcoal filter which is in front of the coolant header tank. Also on the PCV simplification its the perfect chance to install a catch can and I would love to see your way around it. There are no guides online for AGU. I'm assuming I dont have the evap system if I dont have SAI either which then in turn makes this video a bit obsolete for me.
Grant Mac Dee
correct the AGU motor is very uncommon so it will be very difficult for me to make one for you since i yet to see one or work on one i a long time. If you dont care for SMOG the car it will be very ez to bypass all the hoses since your just removing them. The only issue i would see if there is a coolant line or a sensor that is needed for the car to run correctly then you'll need to TUNE it out of the car for it to run correctly.
That music annoying AF
You will live!
Hey so I have done this delete, it sends a code. I’m currently looking for a stage 2 tune, is there some you can recommend that will remove the check engine light for the Sai delete? I have tried just using my OBDeleven to remove the code but it just keeps coming back.
If i dont use the resistors will it cause perforance problem ?
Correct!
how can the blow-off valve be controlled directly from the intake manifold?
SAI, N80 must be disabled by reprogramming the motor control unit
One question tho..... How ard we gonna have to smog here in cali... i see u from from so cal .... im guessing it dont pass visual?
My cars are registered out of state
@@PincheALsGarage damn it smart
If i just cut the wires to the sensors id be using resistors too, it would just cause a check engine light since I already have a SAI delete? Not worried about a check engine light, more worried about bay cleanliness
Hi guys.. I just did this and my car is boosting like crazy! And the power is way more than before! Is that normal? Just worried something gives in.
I still have the big rectangle box with the air filter in it. one of those black plastic hoses that run down to the sai pump come out of it...
can I just cover that hole on that bòx??
Yo I did the full sai delete just curious what u do with the little Pcv valve not the hockey puck do u still need it when you chop off the unneeeded part of the brake booster I’m running mine without right now I have a catch can but I haven’t installed it yet I don’t know if I wanna use it anyway but it came with my block off plat and resistors is it ok to run without it
I have this same set up on my MK4 and I need to know how to hook up a manual boost controller HELP!! LOL no seriously I need to know
prob the best video on yt for sai delete
Funny how one of those plugs you get with the kit actually fit in the hole where the combi valve came off. I used a bolt for that other hose because it works
How do you guys pass emissions with the SAI removed?
Out of state registration
Top of throttle body that you capped off, that went to a check valve leading to a hardline under the fuel rail. What did you do with that hardline or after the check valve vacuum ?
“This little spaghetti one” 😂
how it looks for 1.6 apf?
Can do this on my Audi TT mk1?
What's the benefit of doing this
