- How to delete / bypass n249 valve system on VAG VW, Audi, SEAT, Skoda 1.8t engines. Car shown is 2004 Seat Leon Cupra R BAM 225.
Parts required:
4mm internal diameter silicone hose (for both n249 and fuel pressure regulator)
Zip / Cable ties
Awesome guide mate can’t wait to give this a go once I’ve got the metal plate off lol
Nice one buddy.
Simple and easy to understand better the system.
Thanks a lot 👍🏻
Thank you for taking the time to comment!
So I’ve got a TT, not a gti, but same engine with a K04. Your engine bay looks nice, and your video helped me with some N249 delete questions. How about your catch can? How did you make that set up?
Never understood this mod. I just bought an upgraded diverter valve and went on with my life.
Does deleting the N249 causes anything bad to the engine? I watch a lot of your videos to do staff in my car, very helpfull your videos are 👍👍
Yer it's there to help the DV if your DV breaks then n249 saves you
Hi I can't wait for you to start on the SAI. (So that I can also)
no SAI on cupra R watch pincheals garage vid on it.
Could you please help me with this question? On my N249 one of the valves is capped off. It's the back single valve next to the electrical plug on the N249. My turbo has worked randomly since I got the car. I have no fault codes so I started checking things out and noticed the valve was completely capped off. I really want to put a vacuum line on but have no idea where to run it. There are no other modifications to the n249, the two other valves have vacuum lines running too where they need to go
Quick question I have the pipework ready to fit. I want to do this n249 but some say to make sure u use a resistor. Your not using one are you? Love your videos and helps so much will do catch can next
TANAKA-UK thanks so much for your support. I've left the solonoid plugged in and therefore don't need a resister. You'll only need one if you're taking it off completely. I've not had any problems or lights on the dash the way I've done it in the video.
Or when doing Stage 1/2 just remove the n249 from the ECU.
Hi, is it 4mm hose for both lines? Thanks
Yes it's 4mm silicone tube for both the N249 and FPR lines. Thanks for asking!
i have a question maybe its common i have a seat ibiza 2001 chip tuned to 220hp and im having problems with my airmass sensor it stop my turbo from working but when i reset the cpu its back to normal and then during some time randomly happens again and stops my turbo from working i cant really explain it better but maybe its common and u know something about it
Someone has done this on my cupra r, the n249 valve is missing is that why I have fault code reading n249 open circuit?
There shouldn't be a fault code if the solenoid was left there and the line from inlet to DV has no leaks.
@@RedlineRevs the n249 was missing, I have just ordered one after seeing this video. I had a fault code come up with lamda sensor and n249 open circuit which I assume could be due to not having the valve in
@@dragonclubracing8669 That's what it will be mate. We leave the solenoid attached because it prevents the ECU throwing a code.
@@RedlineRevs whats the point of this delete?
Did any of you get a 17608 Turbo recirculation valve mechanical malfunction after doing this delete process?
Should it be related?
Thanks CVNT
Do you need a Tee piece if your doing both FPR and DV lines or are they separate holes on the intake?
Jack Smith they are separate holes so no need for a t there
q did you get all your hoses in 1 kit and from where if yes .thanks for the video thumbs up
this video is older but I have a question and hopefully you will see it or someone will. there are 3 lines that go under that front bracket, what do I do with them? because it looks like all the lines that are supposed to be up front are gone.
Would that be the same setup as the ARY engine code Audi TT 180 Quattro??
I want to do this to my A3 1.8t but haven't got a clue? Could you give me more details like a step by step?
Hi Xenia, I'm sorry if the video wasn't clear enough. What engine code is your 1.8t? I think the procedure I've shown works exactly as shown for BAM and AMK- other 1.8Ts might have the n249 solenoid located under the plastic cover next to the inlet manifold.
Xenia Newson look up r tech performance in the UK. Please bear in mind this is considered stage 2 tuning and the ECU will need a remap.
just rip that shit out, and run a line from your DV valve to your inlet manifold. done
Hi, unrelated but what is the red pip you have replaced to the left of your engine? Is it a brake vacuum hose? Also can you post a link or message me with the part number please. Many thanks.
What if I have the fault code
What size is Allen key?
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

Says one that doesn't change their spark plugs.
Does anyone no what its actuly for i think its for the traction control to cut boost but im not sure
Does it cause a check engine light?
If u unplug it u need to get it mapped out in the ecu
is this the same as the fwd?
steam buns no
Hi,
I have a serious problem with my VW Golf Mk4 gti 2001. When I floor the throttle, rpms reach a certain point where the car starts to shake and this happens with every gear. But if I push through that point, the studdering goes away. Until I slow down again, and floor it again, it comes back. I was told it can be my turbo. Throttle body is fine. But watching this video has made me think it can be multiple issues. Can you clarify to me what exactly the problem is please? I have used a diagnostic tool on my car and no code show up. No engine light too.
James could be a stored misfire code, get someone with a more in depth scan tool to check it out, misfire CEL only shows up if there’s a certain amount of misfires in a given time
got it
I've done it to my cupra r and it was a waste of time had no boost and run like sh*t
Check ur pipping mate i done it to my vrs and the turbo was chattering amd i had near on no boost
Jack I done a complete removal of all pipework on the area and boosted like crazy lol. But I've sold the cupra R now mate, got a focus st now lol.
Oh I loved my skoda Octavia vrs, thing was highly modified, not many people could keep up ahaaa.
Never do this to any 1.8t. you will over boost you turbo.
Diego Bolt Not if you get it properly tuned!
This isn't the N75 valve, which regulates your boost pressure. This is the N249, which sends a signal to open and close your DV based off of intake vacuum and a computer system. All he did was remove the N249 and vac resevior, meaning when he goes into vacuum (lets off throttle) it'll immediately send the signal from the intake manifold to the DV to open the DV, and when he boosts, it'll do the opposite, which will close the DV.
Hey
Would have been good video if he actual showed what he took out :/
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.
