Sometimes when I'm driving my 987 2005 boxster 2.7 tip at around 50-60mph I sometimes hear an intermittent twittering noise which seems to be coming from the back-right-hand side of the car. It's a difficult noise to describe, perhaps it sounds like a garden sprinkler. The noise only lasts for a few seconds at a time. Has anyone else experienced this or know what it could possibly be?
Thanks,
Tom
