there's a real high pitched noise sometimes, but it's been there for a couple years now at idle that might be the sap. any way to test the sap?

on a 2.8 it's located on pass side lower front of engine..it operates for about 20-30 seconds

on cold starts. The hoses tend to break. There is a way to activate it with the VAG but I forget how. I have to step out right now but I will have to search anyway because I have a problem with my air pump too. One of the rivets broke on mine and it is leaking from the seam of the pump...I think this is an unusual problem though.
