    W208 CLK 230K Squeaks under low throttle or idle

    Hi all My 2001 W208 CLK 230K has developed a high-pitched squeak when the engine is idle or revved up to around 1500rpm. I think it may be bodywork as the same squeak happens very slightly when I shut the driver's door! Has anyone experienced this before? Many thanks all! Pete
