Wastegate quesiton

[looseboost]

If the lines from the wastegate fell off what would the outcome be?? Would i be able to see those lines if i look underneath the car??

You would over-boost to hell and back. If you look up in the right spot at the right angle you can see them.

Yeah i talked to a tech at audi and he said if my turbo was blown i would be blowing out black smoke is this true?? because my turbo was leaking a little oil into the lower intercooler pipeing. The car right now is REDICULOUSLY slow... like 4th gear to 6th Is quick but 1 2 and 3rd gear are terrible. My car is stock i raced a new stock SI 2007 from a 2rd gear roll and it smoked me by 2 cars. i know for a fact i should destroy those cars they run like 15.2. I can hear both turbos spooling up and i have physcially check all pipes and made sure they are on secure. i was also checked the lines uptop when i replaced my AUX water pump. I will be ordering my pressure tester tonight but what do you think... ALso my DV's have never been replaced with 90k miles oin it do you think this would have anything to do with this problem??


P.s thx jerbal you always answer my questions quick and without flamieng on me for being a noob in this area of tech lol

From what i've seen & heard dead turbo(s) would/may lead to heavy white smoke and/or obvious siren/dentist drill/scraping noises from the turbo so it's probably just a large boost leak or a bad DV, so i'd say you're right on track with where you're going.

A reasonable bit of oil in the intercoolers/piping should be considered normal.

not sure who's video this is.. but... here are the dentist drill sounds of a blown turbo

ps... one way or another, change those DV's. 90k miles??? donesky. at least get some 710N's

boost gauge?

u has one?

[looseboost]

no boost gauge
and No white smoke at all even when im high up in the RPMS
and none of that siren sound the turbos sound like there both spooling good .
Could this be a faulty DV?? i was thinkin mayb they were getting stuck and not passing air threw??

[offroader1006]

that's not how DV's work.

they only let air through when you close the throttle.

you can clamp the dv lines and see if it builds boost.

but you don't have a boost gauge, so how would you know?

[looseboost]

Well if it was a bad DV would it result in the problems that i said b4?? (boost loss)

[The_Jerbel]

Sorry, I've been away from the comp.

To answer your Q, not really, it would result in over-boosting. I would suggest a pressure test and also use VAG to pull codes...

[looseboost]

Yes i will be doing apressure test assoon as it comes in thx
