What's the point of N249 bypass, evap removal, secondry air system removal etc

[peter_cupra197]

Hi guys just a few quik questions

1. what is the benefit of doing the following: N249 bypass, evap removal, secondry air system removal, and there is a N....... bypas cant remember exactly but you get the idea lol any answers would be appreciated apologese as complete nooob lol

 

[Razor]

A possibility of better handling and more acceleration due to your WALLET being alot lighter

Ok i'm in a good mood so I'll give you all the answers you need before others give you shi t (and they will!) This question pops up like rain in the UK/Netherlands lol

The N something you are referring to is the N249 valve (black box on top of manifold). Then there is 2 n112 valves which are located next to the black box, 2 copper looking things with plugs going to them.

You can remove all this. Best place to look what they do is this thread

thanks guys but is there a performance gain??

 

[acidstrato]

no performance gain what so ever regardless of what any half wit says or trys to cook it to sound good

the biggest and only real advantage is you can bin all the ugly **** on top of the engine and theres less things to break down

 

[peter_cupra197]

thanks for the info guys think i will give it a miss for now seems a bit tricky for me lol

 

[Reuvers]

no mate then you're not reading it right. its piss easy really!

as said no performance gains. Some including myself noticed their dump valve become slightly louder, but a lot of it is in your head haha

as said less chance of something breaking like an n112 falling on manifold (speaking from experience here hahaha)

 

[acidstrato]

i'll put my hand in the air for n112 falling on to manifold as well, melted wires aint fun

 

[Reuvers]

nope gave me all sorts of codes I didn't like lol

 

[ian_cupra]

mine fell too, lots of short to earth faults ooops, you must have been feeling good reuvers

its all really easy to do, just need a few resistors and some vac hose really, get it done

Fancy doing mine then lol.

 

[ian_cupra]

depends how much cash is involved

 

[lm_gauci]

I think i'll give it a go myself, lol. Grimsby is quite a drive from me.

 

[ian_cupra]

just a little one

yeah made me feel all warm and fuzzy inside

 

[Mat]

think i need to do my 112

 

[Reuvers]

you still haven't>??? would have thought that to be your first modd when going from 1.4 to cupra...

 

[Mat]

it was supposed to be one of the first, never got round to it. N249 was already done

need to removed SAI (secondary air intake)

 

[Robbie C]

Finsihed doing mine tonight

Had already mechanically bypassed the N249 but removed the SAI, fitted my catch tank and removed the N112s for resistors. TBH with all the small bits you need to do the job properly (EGR blanking plate, resistors etc) it's surprisingly expensive for what you get out of it but meh, looks a lot neater and is much less to break, which these things have a habit of doing.

 

[Reuvers]

expensive?? how did you get to that?

3 resistors at +- 5 quid
blanking plate another 7 quid
1 or 2 meters of 4mm vac tubing maybe a fiver

Then the catch tank was an extra that you chose to do, but even those cost only around 30 quid.

seems real cheap to me tbh
