2000 ml320 weird engine noise

Hello again...
I am getting a weird high pitch whine fromthe front of the engine... i have narrowed it down the the black plastic housing at the front of the engine, right in front of the intake manifold. The noise only happens when the engine is cold and shuts off shortly after, depending on how cold the weather/engine is..
Is this something to worry about? Could it be related to the egr problem i posted about earlier?
