Title: Screw in a pipe in engine bay, don't know why
Post by: Rossimac on August 03, 2020, 12:04:02 pm

I don't how else to put this, but I found this on my mid-2005 GTI.

I think, from looking at other pictures online, that it's meant to go via a pipe across the engine to this location, but I'm not 100% sure as I can't find detailed pictures of it.

Here's a picture I found online

Does anyone know what it was and why someone would remove it and block it up with a screw?

Thanks!

Its been blocked to stop a vacuum leak

That's a diy fix to block off that pipe.
there is a specific  vw plastic cap to cover/block off that bit for a mk5.
as long as it's not leaking you're all good to go...

Don't think it's causing any issues, so will leave it alone! Thanks!

As mentioned it is supposed to be blocked off with out engines and there is a special cap that TPS/dealers can sell you to tidy it up.....although it is green now, as recently got one when I replaced that valve.

I think maybe someone has run a boost gauge in the past? 

Early elbows didn't have that spout (mine doesn't), but I've seen if you buy a replacement vacuum pump hose now, it comes with that spout and is normally plugged with a plastic bung.
