hi guys, 2 hours ago i've gone for a ride in the s2 and it was good at the beginning, no problems, but after 30 min or so the car began to lose power on boost, like before more or less, it bog down on full throttle and regains rpms and acceleration if i lift a bit the foot on the gas, tomorrow morning i will check all the pressure hoses hoping one of them popped of a bit

[Olimat]

i may have found the issue

[Olimat]

it goes in this valve

[Olimat]

[Tractor Dave]

That will do it

[psiconauta911]

Had that to once!

[Olimat]

thanks guys, im gonna replace it as soon as possible

You should be able to find a silicone replacement.
It's worth replacing all the hoses that see boost pressure including all the original cotton braided rubber vacuum hoses.
The only one I like to keep OEM is the throttle body hose, the silicone ones don’t fit so well and tend to pop off.

[Olimat]

Yes I replaced every other pressure hose with silicone ones, i was unaware of this one, I found something in silicone but its crazy expensive compared to the others, im gonna search a bit more and if I still dont find the solution Im gonna make it myself with some silicone tubes and the T connector, thanks for your attention guys.

The car is now fixed???thanks guys

I feel like the car is fooling me, its back at it again, maybe i'll try to replace the pcv valve and the n75 valve, i also forgot to mention I disconnected a 1 way valve for the diff lock engagement that was broken and made the car lock the diff when the boost came in.
