    Did it sound like a wooshing sound... Kind of like a distant police siren... comming and going...

    If so then it MIGHT be bad news for your turbo...

    On my old Astra H 1.9 120 I managed to blow 4 turbos in a row... Long story why... lol... but when the turbo was heading out it started making a noise like a distant police siren.. effectavliy a spooling up and then nothing then spooling up noise... As soon as I heard that I knew my turbo was going to fail... And they always did within 18 to 1000 miles of the sound comming...

    Fingers crossed this is not the issue for you bud!

    If the MAP is on the way out, it can cause the boost to hunt agressively but you would need a boost gauge or an OBD II port reader to see that.
