I have a high pitched squeeking noise upon light acceleration. It seems to be inconsistant. But, you can hear it. Any ideas on what it could be?

    Sometimes you can hear a similar sound when the breather system (PCV) failed.
    A BMW specialty shop should be able to check the PCV pressure with a manometer.

    If the sound is originating from the right rear wheel, it may be the brake pad wear sensor. It apparently will "flex" enough and make contact, producing the squeak. Really annoying; a local BMW shop should be able to adjust it, but it may set you back ~ $100. Design-flaw.
