Howdy, my new to me 2006 CLK350 with just under 60K miles (which I have driven less than 10 times) is throwing a 0522 code (Tumble flap Intake Manifold). The symptom was extremely rough idle and a blinking (CEL/MIL). The code reader pulled a number of cylinder misfires as well.
The problem seems to be intermittent as the car is now running fine and and the code has not returned. I have only taken a short drive around the block and all went well.
I'm reading the recommended solution is to replace the entire intake manifold. FCP Euro has one for ~$700. Or the flap levers repair kit (which both require the removal of the intake manifold).
Short of that has anyone successfully removed the carbon buildup without removing the intake manifold? or some other clever ideas? I am of the opinion since it's intermittent that nothing is broken and that the flap is simply sticking.
Thanks in advance,
