20vt driving me crazy!

[ibizacuprafaded]

Hi,

I'm fairly new to Seats and this forum.

Got an Ibiza Cupra 1.8 20vt X reg, had it for about a month now. Its got a K/N induction kit, front mount, bailey re-circ, cat back system. Recently its started to not boost properly but not all the time. It feels like its holding back, I have changed all the Vacum hoses and checked the boost hoses but no joy!

Please help, going crazy!!!!!!!!!!!!!!!!!!!!

Do a search my friend. You tried unplugging your maf ? see if runs better ??

 

[evans1089]

Get it serviced mate

 

[ibizacuprafaded]

will try un plugging maf tomorrow, thanks

Dosent need a service, had new oil, filters and plug when I got it to be on the safe side.

Its completely random, boosts fine 1 miniute then not another, also the Vacum on the guage reeds lower then normal if that means anything?

 

[turbo009]

if it runs better with maf unplugged its your maf. Good Luck

 

[evans1089]

you checked all your pipes? none are loose are they? the induction kit clean? if they are dirty it can restrict the air flow..

 

[ibizacuprafaded]

all pipes have been checked, put a brand new cone on yesterday and made no difference. The cars runs/idles perfectly untill you put your foot down then it either boosts fine or dosent!

Vag com it.

Sounds like a coilpack to me buddy. As Phil says though. Get vag com on it and see what it says. Seat have been kind enough to provide so many sensors on the things that go wrong so that you can see what is up straight away, so you might as well take advantage of it!!

i see that in the months that i;ve been gone, little changed.
Going by what he is telling us, you lot can guess, but you're really pissing in the dark. As phill says: vagcom is the only way to go.
Get used to it, driving these cars, vagcom is your best friend

as phil says vag com it...Have you tryed a n75?

 

[ibizacuprafaded]

Thanks for the suggestions guys, still no luck and now not much hair left!!!

 

[ibizacuprafaded]

Just convinced my boss to order Vag-com for work so hopefully will be able to sort it fairly soon

 

[ibizacuprafaded]

fitted new maf sensor, boost is better but still not what it was? Lamda sensor came up as being faulty now, would this affect it?

 

[DaNnY_LaD]

Yes also have you tryed a new n75?

 

[ibizacuprafaded]

got uprated one coming from vw tomorrow, prob get a lamda sensors as well so can rule it out
