do your vaccum lines
Last week I replaced all my vaccum lines in about an hour after my oil change. At least the ones I could find under the intake. There was one molded one I had to get from the dealer, otherwise I got everything I needed at Autozone.
Just do them like spark plug wires, one at a time and cut to the length of the old one. Didn't see anything obvious, though they were in rough shape and it did clear a code a week after doing it. I didn't get past any of the fittings on the pasenger side near the air filter, maybe someone can suggest failures I should look for over there.

There was another long one I did that went from the back of the underside of the intake up and accross the front of the engine and down to bumper level on the passenger side. It sounds like what your talking about. Then 3 or 4 short ones under the intake.

What year is your car? if its a 2000+ it should have secondary air. Thats the hose I was talking about. it goes from under the intake manifold on a sensor to the back of the valve cover under the metal pipes.

Oh, yeah 2001.5 Passat 1.8t
I looked under the hood today and I did that line. Thanks for suggesting it though. Just out of curiosity, what does the secondary air system do?

Re: do your vaccum lines
When the engine is cold the O2 sensors are basically off-line & the fuel system is in a default mode, which tends to be set a bit rich. The SAI system is then activated to pump air into the exhaust manifold to aid in more completely combusting any unburned fuel that may be left over.

Re: do your vaccum lines
That answers a lot. When I'm working under the hood and I start the car, I always thought I was hearing a vacum leak, it would go away after a few minutes. Now, I believe, it was the secondary air pump.
