[docteursupo]

hi , escuse me but i 'am french so if my english is bad sorry ...
so j explain you my problem , it's been a long time since I felt little interruption when i accelerate. And I have the feeling that my car is not at its full capacity. I changed my debimeter but it is still not working. And my turbo pressure is ok. And I went to SEAT and they verified my VAG. And they found these problems
16795 P0411 035
Secondary air system
Awry flow

i hope you ll find my problem because i am very angry because I run VS a full stock 20VT and we where égal , and i have a reprogramation 1 BAR a DV bailey , green air filter and N75 J vanne .

so thank you for your answers !!

this problem is popping up so frequent now, its so common

# Check Vacuum Hoses/Pipes to/between Components
# Check Secondary Air Injection Pump (V101)
# Check Secondary Air Injection Solenoid Valve (N112)

these are the only things that you can check for yourself really

 

[docteursupo]

ahhh ok ! i test with an other valve N112 and its not this ... but what is the Vacuum Hoses/Pipes to/between Components ????

 

[acidstrato]

all the small black braided hoses on top of the coilpacks that connect the n112/n249/n75

 

[docteursupo]

ahh okok i ll check this thank you ! i hope ll not change my pump...

 

[Ibiza Cupra]

I hope you don't change the pump. that'll be a fair few euro's!!!

 

[docteursupo]

yes sure ! its **** , i ll déconnect MAF to see if its from this ..

 

[Ibiza Cupra]

NO!!!!!!!! Check your vac hoses, You probably have a split one!!!!! Thats all. Go and get some more vacuum Hose and change all of them if you haven't already.

 

[docteursupo]

hummmmmmmmm ah split ! and where i can find this ???? sorry i am a newbi , and french ! so i difficult to anderstand but i prefer doing effort because french forum are not technical like here héhé

i read that people have a noise when they start engine ... and i have this noise and he never stop.. maybe its an indice to find where is my problem ??

 

[Ibiza Cupra]

As in cracked, If you still have the original hoses just change them. Go to a spares place in France and ask for some vac hose.

 

[docteursupo]

i just look all my hoses and j dont find a split.... maybe you can show me where j must search ???????

 

[David_smith_909]

Where i have arrow'd to on here

basically all the blue hoses, their the VAC hoses

 

[docteursupo]

ohhh cool ! thank you english are very stand together !! i ll see this but you think
its a bad idée to deconnect maf ....?

 

[JIMYU]

you can disconnect the maf for a short time. if you don't notice any difference or the car is quicker then your maf is probably dead.

my vacuum hoses were split and in really bad condition.. Some new hoses (around £5) sorted me out

hope you can sort it soon!

 

[docteursupo]

yesterdat i checked my hoses and they seems OK , i ll put my original DV and i change my N75 vanne because i have a N75 J in my garage and i ll test , otherwise i dont know what to do

do you buy your hoses on ebay or seat ???

 

[acidstrato]

forge motorsport usually bud...they shouldnt have any problems supplying you any if you want some. but if your standard hoses are alright then it prob wont sort out your issues

did you disconnect your maf and test?

you could try resetting the ecu by disconnecting the battery for 5mins sometimes the simplest thing can correct a problem

 

[docteursupo]

i ll test to disconnect the maf this afternoon , but i have this problem since a long time ago ! and i tested with the batterie and its always the ****..
