hi guys,

i have a EU-FC S5. my boostgauge was showing vacuum all the time, under heavy load it went up to 0 and not much more. so we thought i had vacuum leak. since i have no german (or europen) plan of the vacuum lines, we used an american one from th FAQ-sektion, the factory manual for the S5.



before, it was like shown on this picture (with the cap on the upper pipe)



im a bit confused, what is the right one for my car? i have tested both options, there was no noticeable diffrence i think..

thank you guys, and sry for bad english

 

no ideas?

the second picture was a plan to install a JDM aftermarket BOV.

 

so what are you asking exactly?

BTW: your english is better than many americans on here, lol.

 

hi, thx

what are the differences between this 2 options? and why the hell is the upper pipe terminated.

 

none of you T2 guys know about this? help the poor german out! theres probly only 3 FC's in his whole country, lol.
