Check the intercooler hoses. Mine did the same thing when my IC hose-clamp needed to be replaced.

did you hear a big gush of bov sound....or did it just pop



i know when my BOV pops off sometimes, stock hose on the alum pipe, itll make a super loud bov noise, but itll still run...



a vacuum leak from the IC system shouldnt stall the car out....itll just have no IC pressure and no boost....



ive driven with my IC off before..but not boost



i really think the engine sounds blown

A vacuum leak (popped hose) from the IC will make the car stall. How do I know? First-hand experience.

ok.... my car will drive with the ic disconnected

Both the AFM and ECU are different for the S5. Maybe that has something to do with it?

oh true...i forgot... the map sensor allows that kinda ****...haha





well back to the topic at hand....compression results?

i did the quicky test, both rotors have the big "whoosh" noise. Im trying to do this quick since it will be dark soon. I removed and reinstalled the intercooler, and all is fine.. EXCEPT this...

another pic

should be 3 "whooshes' on each rotor.

Hello mr. vac leak
