Is there a recall in the works for this issue?

Yes, there is FINALLY a recall in the works for this issue. My dealer/mechanic just contacted me this morning to say that a public announcement is imminent. I had to have the intake manifold on my 2008 CLK 350 replaced last fall and found many online entries from others with similar issues, so it's about time Mercedes takes responsibility. I was told that refunds are on the horizon for those of us who have already paid for the repairs, and of course, the Recall itself is pending for those who have not already addressed the problem.
