03 a4 1.8t vaccum problems... maybe a valve?
Got an 03 A4 1.8t. Lightly chipped and no other modifications.
Heres the issue. Under acceleration I can hear a hiss from the engine
compartment. No noticeable change in performance but sometimes when I
come to an idle, its rough and I can hear a little hiss. I get out..
pop the hood and identify the source of the his... and give it a
thump. The valve snaps itself together, the hiss goes away and the
idle returns to normal. What valve is this? Does it normally snap
apart like its doing? If I removed it from its assembly I believe it
would just fall apart. Is that normal?

This is a shot of the engine compartment with the questionable valves
location circled.

This is the actual valve. You can see the dust free fingerpriunt on
the side when Ive been pushing on it to pop it back into place.
Any ideas?

Its not normal. i'm forgetting the name for it and its proper
function, but its part of the vacuum line and its linked to the brake
system. Apparently its a pretty common problem with Audi. I just
taped the split together (where it keeps popping out from) and drove
my car for about a month until I got a chance to change it. Easy fix,
took about 30 minutes in all, part cost less than $50

Re: 03 a4 1.8t vaccum problems... maybe a valve?
Ok... I took the valve out. Its a suction pump. part #058 133 753 b.
Why would the end pop off of it like this? Is this a sign of some
other problem in the vacuum system?
The valve (or pump, as its called) didnt fail or clog, that I can
find. It just seperated into two pieces. Being held together by the
tension of the hoses that it uses to function.
here is the whole pump....
http://jake.rakestraw.com/images/whole.jpg
and here it is with the valve assembly snapped apart
http://jake.rakestraw.com/images/broke.jpg
Is the popping apart of the pump a safety measure to keep something
else more vital from exploding?
