i am having a problem with this whinning in the engine. It either happens at start up and doesn't go away until it is warmed up and sometimes it doesn't go away at all not matter how warm the engine gets. It seems that the whine is from the engine. Has anybody else had this problem? if so what did you do to fix it. i was at the dealer getting an oil change and the service manager noticed it as well. He is not really sure about it but he thinks it might be the idler pulley or tensioner. well chime please for any help on this matter.
