Amen to that. In fact, after the S54's main bearing problems, NONE of the S65s should have had it. I'm in the possibly affected range, with a build date of Jun '08. This is what is making me reconsider keeping this car after warranty. And the idle valve too... if it doesn't fail before warranty runs out (low mileage here).

Who told you this? There's no valve inside the exhaust. Maybe you're referring to the heater that heats up the cats on cold starts . This thing looks like a fan, and sits at the back of the 'V' when you remove the plenum (below is a pic of it), but it wouldn't make that noise at all. And there's nothing else connected to the exhaust.
