just did this this in ten minutes, I have about 30 feet of extra vacuum line from my brother's Saab 9 5 Aero High Output 2.3L Turbo. It's so easy, anyone, unless they were maimed can do this. In ten minutes
I'm doing this temporarily and maybe put n249 back in service in future. I'm not going to tap into the FPR vacuum though, I'm just going to use the one VW used to supply vacuum to BOV/n249/etc. In this vid, aqualo had already installed the aftermarket BOV and tied into FPR for vacuum. Looks like good installl though. Personally, I would change it so fpr vacuum is dedicated to just fpr.
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
Just got a gti mkv. I recently pulled a p0413. Secondary air injection system switching valve "A" circuit open. From what I've read online this is the n112. Car seems fine. Is this something i need to worry about? From the video I'd imagine the vacuum is pretty much going straight to the n249? Great video btw! Thank you. This has been the only source for me to find this valve. Till i get a haynes manuel :)
what it's that black valve/diaphragm looking plastic piece that goes goes into the hose coming out the intake manifold? Can I use a T? What is the off that and where can I get it? Is it from a different part of the engine? Thanks
+squalo777 videos I can't view it, the link takes me to Google play butt I already have the app installed. I'll find it through the listing number. There's the one hose coming off the bottom of the intake that connects to that black ball thing and then the other hose goes to the front side where the valve is she it works plug in. I'll take a screen shot and post it on Microsoft One Drive, I'm out of space on Google drive. I think One Drive odd unlimited because I have a Microsoft account through xbox live
it was a bad coil pack sending the car into limp mode until I restarted the engine. I just got all new spark plugs, just the stock ngk double or triple platinum, the stock ones, and the red Audi 06e coil packs. I didn't have enough to get the adapter plate but they sell overhead bolt on adapters for cheaper.
+squalo777 videos I was compression testing the engine and realized the 1 coil was misfiring, not severe where it was running idling like crap BUT under load, I don't think it's going to be finished this week but I always expect the worst for dinner reason
Hi man i did the same thing like you do and now i have a error code 17608 - Boost pressure control valve (N249) Mechanical malfunction. Why this hapened? I put the valve conected to the electrical system. I folow the same steps like you, am I missing something?
@squalo777 does this also apply to b6a4 with amb engine code? I lose boost under acceleration but when I let off it builds up..? I know it sounds strange and it's a little hard to explain but eventually boost does buildup and I lose boost between gears
what is vacum line coming from your fpr going to? i have fuel issues or at least i think i am, broke the connector to my n112 valve (what ever controls the sai pump) i just connected my fpr line directly to the intake w/o the one way valve. now my car goes into limp mode intermittently, would i need to connect the one way valve to my fpr? or will be a coilpack issue?
Do not do this, the n249 is controlled by the ecu and can close the diverter valve in cases where it would be normally open, therefore the ecu can create boost in part throttle situations. LET THE ECU do what's best for the engine! It's there for a reason!
I totally disagree!!! If you take a moment to read your comments you saying that the ecu can close the diverted valve when it's normally open witch is bad for your Turbo and I believe that if the ecu can close it when is open and can also leave it open when it suppose to be close right? If what your saying it's right !!!then the n249 bypass would be a good upgrade, cause you no longer need the ecu, or the valve to open or close your diverter valve, when the n249 fails and fails miserably!!! Leaving the valve open and sending all the boost that the Turbo is creading back to the intake, with the n249 bypass you don't have to worry about that it's a direct vacuum line going to the diverter valve, do a little bit more research you'll see it's worth doing it
you think the engine can creat boost by itself by closing the dv??? the dv doesnt build boost.. it simply bypasses boost when you let off the throttle. the n249 valve is a slow reacting valve and when it works it does its job but when it fails its bad and for me it gave me massive turbo fludder.. yes the evc does whats it programed todo but when you have more boost or change the motor at all and the ecu is still running stock it doesnt know what is better for th engine
That is true, but what about letting off the throttle situations. N249 can react faster than the intake. So n249 can let off the boost quicker while intake is still under boost, which is better for the turbo? How much does n249 delete put strain on turbo is the question.
Awesome videos for the most part man...only thing is you talk a little on the quiet side...maybe it's just because I'm watching videos on my phone though. I think you got my sold on the Forge 008 DV though! Your Jetta sounds great! I have not heard of this upgrade though...all you need to bypass it are some hoses and connectors though?
The only thing you need is hoses and clamps that's pretty much it thanks for you comment bro I will try to do them better and is a really good upgrade your valve is going to sound better and is going to hold boost better
Heyyy bro a question to enhance the bypass the emptiness of the blow-off is lost but i see in the video that you get the void of another valve i could tell where and where they connected the hoses that my blow-off lost the void as I`m commenting and does not work well
hey squalo what's up paisa, i just have a question, what do you do whit the hose that goes to the waste gate? i mean were do you plug it after? or do u even touch it ?
hey i did the bypass on mine and the only thing i didnt kinda under stand was that on the b.o.v the hoses that come out were they go i seen one going under the manifold cuz you put T on them
What modifications have you done so far bro how much bhp do you have at the moment I've got a VRS 1.8 turbo 180bhp I have fitted a front mount intercooler a Forge splitter r dv and a boost gauge and a oil catch can I will try and put a video up of it tomorrow depending on the weather over here lol
Kirk k ok i have the 3" full exhaust system front mount inter cooler forge 008 valve the vr6 maf housing n75j k04 turbo i still have to put the injectors and the chip is a 05 jetta gli it came with 180 stock im not sure howmuch power it has rightnow im waiting for the unitronic stage 2+ i would like to see your car it be cool if you upload that video
squalo777 videos that sounds nice man I need to do half of that stuff 2 my one when having the money lol. I must admit I do like the Jetta's And that colour really does suit it nice car bro and I will definitely put a video up tomorrow
Kirk k thanks bro and the upgrades i did them little by little i still have to do the chip im going to try to dyno the car as it is right now and after i put the chip,
Kirk k man I wish I have the right side drive it just look good bro what part of the planet you from bro lol ? I like your cat bro I like the way it looks from the front nicee!!
Ronny D theres no need to do anything with those hoses those are the ones comming from the n249 you no longer need them no air goes through those hoses
OK by doing the n249 bypass you'll be able to hold boost better this upgrade is for the diverter valve or blow off valve the n249 open and close the dv valve and most of the times it stays open and that's how you loose boost if you do the n249 you putting a straight vacuum line for the diverter valve in short words this makes the diverter valve to operate much better
Rini Sugiarto ok the n249 is the one responsible to open and close your bov or diverter yes it give you better throttle response cause your not depending from the n249 to close or open, by putting a direct vacuum line you dont have to worry about leaking air because the n249 didn't close fast enough its a great upgrade and it really really work better than the n249 i have had this upgrade for a year now with no check engine light everything works good and my car hold's boost really good, go to vortex.com you can see a lot of reviews of the n249 upgrade but ether way its a great upgrade
I'm sorry to hear that bro the porpuse. of the n249 upgrade is to have a direct vacuum line for the diverter valve if your boost was normal before this upgrade check all hoses for a boost leak I have had this upgrade for .a year now I did it cause.I was having problems with the n249 getting stuck open all the time and I was loosing pretty much all the boost thats why I bypass my n249 the diverter valve just needs a vacuum line to open and close the n249 is responsible for opening and closing the diverter valve this is just between the diverter valve and the n249 the only way you can be loosing boost is if your diverter valve or blow off valve is stuck open and is bleeding all the boost back in to the intake check all your Hoses for leaks and most important check your diverter valve I really hope this was helpful and I hope you solve the problem with your car good luck bro

+squalo777 videos yea I ended up reversing the n249 bypass ...which was a bitch btw you know how many connections there us back there. ..anyway come to find out it was my N75 ..so I unplugged it and ran my mbc solo... my boost spikes up to 15 at the highest and. down to hold at 8. psi in every gear . what could it be ? I've checked all hoses no leaks ... im running stock ecu on 01 jetta ...it's only suppose to run 8psi stock
+B_RAI_08 do you think it's my map sensor telling my ecu to cut down boost? .. should I do diode mod? ... also I tried unplugging my wastegate actuator and I still loose all boost down to 8 after spiking to 15.
if you have a stock ecu you should be spiking at least 13 psi and holding 8 psi your are not loosing boost bro is pretty normal you always going to have a spike of 13 to 15 and hold 8 with a stock ecu believe me bro it's normal if you wanna be able to hold more boost do your ecu upgrade right now your engine is very healthy except for the part when said you unplugged your n75 in most cases when you unplugged you'll only boost 5 psi so remember to keep your n75 plugged
greg h LOL...No.... Just curious why you don't just flash the programmable ECU that runs your engine and manages the Turbo...There's more power to be had by doing that, and it is the correct method...this way is silly
LetsPlayDaPc Stock DV sucks ass and is super weak, can barely hold any more than stock boost. My 1.8t is equipped stock with the 710C diverter valve, and I just used an MBC to bump up my boost to 11 psi. Almost immediately after I started hearing the diverter valve diaphragm humming and being under a ton of pressure it isn't built for. I'd recommend the 710N for a DV upgrade, it's the stock Audi TT DV and is strong enough to handle about 18 psi, while being a good, cheap OEM component.
@@DJROBONE1 did you find out why you were losing boost and backfiring? My car is chipped and used to hold 19psi, now it only holds 14psi and backfires at high rpms

Man I wish some jack as* didn't do this to my car before I bought it now I have to watch you so I know it's done right thanks for the vid
im glad the video helped! instead of investing time and money in a mechanic shop i invested money in tools
What about those 2 hoses under the intake that you said you don't need anymore? Should they be capped off???
I had a plan till I watched this ...just confused the fuck out of me
some say it's optional to put hoses on the resistor? some say it's better .. what you think ?
I'm doing this temporarily and maybe put n249 back in service in future.
I'm not going to tap into the FPR vacuum though, I'm just going to use the one VW used to supply vacuum to BOV/n249/etc.

but you lose mid throttle NA mode and under low boost it bogs tried it years ago not happy with the results, just like 90% of the vortex
hello just wondering what's the other hose on the right on the 3 way hose adapter? thankyou

Thanks for the video very helpful top man
Kirk k no problem bro glad you like the video if you have any problems with your 1.8t just let me know i know this engines really good
Thanks a lot bro more than likely I'll be asking you a few questions lol
