boost getting annoying now.

[nick s]

what is the name of that unit that you can remove and bypass that stops the dump valve releasing boost? i have a feeling that's what my car is doing. if it gets a bit hot, or i change gear too fast, the boost will drop from about 16psi to 8psi for a few seconds then shoot back up again. it does it in every gear sometimes, then 2 minutes later won;t do it at all, then will do it again?! v.frustrating when i'm trying to have a friendly play with something. i was having ago against a pulsar last night and held it at 40mph in 2nd, we both went for it and i was fine in 2nd and 3rd, then all of a sudden the boost dropped in 4th and then went up again after a few seconds. happened to my mates ibiza and he removed this box thing and now he says it hardly ever does it. is it n249 or something? could this be causing the problem? thanks

Yep, it's the N249. Do a search.

Hooch removed mine for me and it smoothed things out. Much better to drive

got rid of mine too much better, removed it but left everything plugged in as far as wiring goes just tie wrapped it out of the way.

Wayne, does it really make that much of a difference?

Mike keeps umming and arring about it

 

[Cupra_Wayne]

It does yes.

 

[seli_babe]

It does yes.

You not had any issues??

 

[Cupra_Wayne]

You not had any issues??

Nope. Was a big improvement imo. Drive is so much smoother and no more dropping boost. Well worth the 5mins it takes. Tidys the bay up as well Also makes getting to coil packs easier when they go (not if! lol)

 

[nick s]

wayne - were your symptoms similar? boost really drops for a few seconds then goes back to normal and randomly does it?!

do i need to buy a bit of silicone tubing to bypass it?

 

[Cupra_Wayne]

Had boost dropping etc. Yeah you'll need some tubing, not a lot mind.

Hi wayne
was it 5 min. including the resistor needed not to throw a CEL??
That part seems a bit complicated to me.
Sim's guide is great but seems hard to follow.
Thanks

Just leave everything plugged in electrically and by pass the valve itself with 3 or 4mm tubing.

Like this..

So is the n249 or n112 disconnected? or are they not? just a tidy-up job?
Where did you run the 4 mm tube from and to?

 

[PhilW]

All been covered loads of times. Have a search.

 

[Noam]

I know of the traditional SIM way of doing it.
All this started when wayne said he did it in 5 min .
That seems quick and easy compared to SIM's guide .
So how did you do it?

 

[ChrisCurzon]

i been wanting to do this to but could work the guid out and what to do with the resitor but if can do ti without be good.

gettign some silicone vacum hosing soon so will do it then just need to know where it goes from and to for the bypass any 1 take afew pics to show please

 

[PhilW]

[ChrisCurzon]

yea i had a look at guid just confised me abit but looking at them pics now think i get how to do it looks pritty simple cheers phil

 

[Cupra_Wayne]

It took Hooch 5mins to do it on my car as he's done it before. If I'd done it it would have taken 5 days lol!

It's very straight forward. The guide makes it look more difficult than it really is.

 

[Molehill_Mike]

I'll do this at the weekend I think

 

[ChrisCurzon]

i will do it when i get silicone hose's just need to find some small cable ties to tie the silicone hose's on
