Boost Leak?

[Mefro]

How can you tell if you have a boost leak?

Re: Boost Leak?

do you have a boost gauge?
Or access to a vag-com?

Otherwise, a hissing/whooshing noise can be heard when flooring it (or possibly even when shifting) if it's a big leak...

Re: Boost Leak?

boost gauge would be a big helper for that

Re: Boost Leak?

I can hear wooshing/hissing when im on the throtle, it seems like its dumping continously. I thought it is supposed to dump when you shift or let off the throtle?

Do you feel a lack of power? Is your engine light on? What are you driving?

Its going to be hard to diagnose without a gauge. You might want to consider picking one up. VW really should have put one in the car from the factory but I guess they wanted to avoid intimidating people with more gauges.

True dat. You really should get a vag com and check codes, value blocks ect.

Yeah I feel lack of power, and my check engine light it on. I drive a 2000 1.8T. So only way to tell is to install a boost guage?

sounds like a hose popped off.

Lower IC hose maybe? There shouldn't be any whooshing when you're on the throttle!

Re: Boost Leak?

If an intercooler hose popped off wouldnt the car stall? That what happened with mine at least..

I think it sounds like a torn BPV....

yep, could be that too.
But when I was replacing my lower IC pipe, I didn't put the clamps on at first and the hose popped off...the car still drove, but whooshed pretty fierce when I gave it some gas!
