n249

... can someone please confirm I've got my head round this... I've got a 2002 Cupra (180) and I'm removing the N249 in an hour. Step one: remove hose from top of DV Step two: remove hose from top of FPR and from bottom of inlet manifold that the same hose runs too... Step three: connect...

hey all just joined i see the guide for the n249 bypass just wondering what differece it makes once done thanks

Hello all After reading many posts about people doing an N249 bypass i thought i'd give it a go yesterday. all went smoothly but is there any chance that doing this will actually slow my car down? I'm not sure if its just me but it feels slightly less powerful than it did with the N249? I...

Hi Is there any "danger" of driving around with a open leak from the pipe that goes from the left side of the inlet manifold and to the N249 valve? Nearly got to work and the car started to drive odd. Vagcom said mechanical failure of the N249, opened bonnet and the silicon hose on the...

Hey all, I did the n249 bypass and didnt really notice much difference. i av a revo remap and forge recirc valve and did the bypass but then thought i'd do a temp boost gauge fitting, when gauge fitted the car ran amazin with amazin power and then when gauge not on its back down 2 normal and...

Mainly interested in the boost control system (N249 and assorted hoses etc.) I've found 3 but none of them seem correct (for different version of the 1.8T I expect) For reference here is an image of the LCR N249 hoses shamelessly nicked from the excellent N249 guide This looks...

does anyone no what size silcon hose i need to buy to do a n249 by pass ??? is 3mm ok 0r 4mm or 6mm help please does anyone have a ( before and after photo of the mod???:)

hello everyone Been in the garage tonight and well my n249 didnt look like yours so i thought mine will lol I hope ive done it right in pic 1 and one final question the Fpr pipe was that ok to replace with 4mm silicone hose because the oem was chopped by previous owner so i thought i would...

I need a n249 valve has anyone got one for sale my fell of it bracket and got melted by the turbo:cry:

Folks, My secondary air pump is full of rusty water, and as dead as a dead thing that's been deaded a couple of times to make sure that it's dead. I've found various people who say that the likely cause of this is a faulty combi valve, letting exhaust fumes into the pump, which condense in...

i have a leon 180 with a k&n air filter, turbo smart recirc dump valve these mods where on the car when i brought it. i have had a diagonstics check and it shows Boost Pressure Control Valve (N249): Mechanical Malfunction Pressure Drop between Turbo and Throttle Valve (check D.V.!) Charge...

hi guys! my LCRs pretty much standard at the mo, minor mods ive done are listed below. Just wanted to know, on my setup, will doing the N249 bypass make any noticeable difference?? thanks Vin

Ladies and Gentlemen, I did the below quick guide to bypassing the N249 value, there may be other ways but i think this is the easiest, i created this guide for vagdrivers.net but as there are still requests on here so i decided to post it over here too.. I already posted my graphs showing...

Ive been reading the post on the N249 Bypass but as alot of people seem to be im confused as there have been loads of different pictures of different bays and pipes. Mine is a BAM LCR so where and what should i remove and run new pipe from where to where, i have 2m of red 4mm hosing sat here...

Thoroughly recomend it, much better to drive. No funny hesitation if you take your foot off the throtle just as it comes into boost. Also stuck my boost gauge in, just temporarily, as i haven't got a gauge mount pod yet. Spikes over 20psi, and holds at around 18. So i'm guessing it's already...

Hello all, just looking for your comments, i did a log this morning and noticed my Boost was fluctuating up and down at around 19 to 20 psi, i did two logs one before the n249 nypass and one after, the run after seems to have a more smooth boost curve. Comments are welcome, i plotted the...

after doing a search on doing the N249 bypass all i can find is photos of a Leon cupra r or an Ibiza 1.8t although it may be roughly the same it's dropped my confidence in doing mine as i'm not very mechanicaly minded although small things i can achieve. my car is the 180bhp Leon sport with an...

After reading the threads on this and how to guides I wasn't too sure on how to do it. But once I decided to go for it I found it really easy to do. There is nothing hard about doing it at all just sounds like it. Once done i noticed a slight change in the car nothing major but thats with hardly...

I assume once you do this you end up with a few vac connections that have no hose attached to them. What do you block these up with?

Hi, I've done the N249 bypass but i want to take the valve out completely. I understand that the valve needs to be plugged in so that the ECU doesn't throw a hissy fit. What resistor can i put in place of the N249? Thanks Rich
