BPV Problem?
I have a 99.5 A4 with just about stock everything except for a K&N air filter I put in last week. When the car's in neutral and I increase throttle everything sounds fine until about 3-4k rpms when I get a weird rattling/moaning sound. As soon as I let off the throttle, it makes a couple similar sounds as well. That seems like it would be a turbo system issue and I've read a bunch of posts about BPV issues and similar symptoms.
Also, I'm planning on chipping very soon and thikn it woulf probably be a good idea to get this fixed before I go ahead with that.
Hope I'm not being redundant with other posts but I just wanted to make sure. Any suggestions/input is welcome.

Re: Does it sound like if your blowing over a coke bottle.
Not really...almost sounds like a metallic rattling. At first I though I had left a screw driver in a compartment under the hood...almost like a slight metal rattling against something in there.
