So the other day my car started making a high pictch whistle sound. It was hard to pin point but sounded like it came from the front of the engine. This is the 2nd time I had this issue. Last time it was the oil breather was messed up. I took it to the dealership on Monday and it was the same thing. The replaced the entire assembly. This is the area where the oil filter is installed in the front of the enigine. Under warrant so no charges. They said that the design has been changed and it shouldn't happen again.<p>Just thought I would give others the heads up if they have a similar problem.

Re: High pitch whistle sound - oil breather (x-omatic)

So i take it that they replaced it once before but with the original style parts? The updated parts shouldnt have this same issue but who knows. I know the upper hose shouldnt fail anymore now that they switched to rubber instead of plastic but i cant vouche for what or if they changed anything with the oil seperator <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0">

I had that same exact problem a month ago, its something about the oil lines being clogged up, replaced under warranty... they told me i shouldnt be running the car as much because that noise happens when the car builds pressure under the hood, you want to see the noise go away? take out the metal stick that measures the oil... damn i haven't been here for a while lol

Re: High pitch whistle sound - oil breather (heico2.4i)

Thats because of the faulty oil seperator. Its creating a vacuum in the crankcase so strong that its sucking air thru the cam seals thats the whistle. Thus why when you pull the dip stick or try and remove the oil cap its pretty tough.<p>The updated parts should fix that including the plastic upper hose that cracks and causes the ECM 250A code a lot of people have been getting.

I've just sent my car into the workshop 5 mins ago with (i presume) the same high pitch whistling noise. They have yet to contact me back with their findings. Hopefully it is not other underlying problems.
