California, have you considered selling the car? Your giving yourself an ulcer and you really don't even have a problem......yet. My 2006 was "definitely, 100%" within the affected range and I had 3-1/2 terrific years with it, taking it from 38,000 to 77,000 miles during that time. I only panicked AFTER getting intermittent CEL's throwing P0016-P0017 codes and being told that was the beginning of the dreaded issue. So a car that cost me $22,500 in September 2009 took in $12,500 in March 2013. I don't recall you saying what kind of a deal you got before you "jumped on" this car, but you did say it was pretty. My 2006 looked far better when I sold it than when I bought it, after I added a spoiler, nice wheels, and some OEM mods.
(yes I think they made them)

My worst fears are
1.) Metal shavings in my engine (there are pictures floating around where the teeth are completely gone from the sprocket, one is in the TSB), and
2.) The timing chain falling off or skipping time on the crank or cam sprockets while the engine is running.

Those are big concerns of mine, too. I know some people have talked about doing oil quality tests to see if the gear was dumping particulate, and the findings were "inconclusive". There will always be fine metal particulate in the oil - that's just part of normal wear and tear on an internal combustion engine. And even when properly forged, those sprockets and the timing chain will wear away over time - I'd give them a good 300K miles or better. What I would fear is a large chunk of a sprocket tooth breaking loose and going for a ride in the engine.
As for the timing chain falling off or skipping, I don't see this. As long as the main crank sprocket and cam sprockets are solid, and there is some part of the idler sprocket for the chain to ride on, it can't get too far out of time - just by the shrinking diameter of that idler. Of course on the V6, if the idler sprocket goes completely, then the balance shaft would skip or stop rotating and that could cause all sorts of vibration problems.

Uh... years and 20,000 miles later, my transmission fluid is brown and the MB dealer is still saying that it is not MB specified to drain the CLK transmission fluid altogether. Glyn or Rudeney, will you please post for me again the MB 722.9 procedures for draining ALL the transmission fluid on my 2006 CLK350?
It is shifting too loud and too hard from reverse.
My car does have the drain plug, correct?

Here are the WIS docs:

Yours probably has a torque converter drain. If not, then change what you can, then do two more changes over 60 days and you'll be pretty close to getting it all fresh. You can use an infrared thermometer aimed right at the pan to check the temperature.

Mercedes-Benz 2006 CLK 350 Cabriolet
I recently bought a 2006 CLK350 Cabriolet and did some research which stated there is problems with the balance shaft and steel gear wearing out. My CLK350 has almost 140000 miles with no check engine light and I had it scanned today which showed no codes..The care runs fine and hopefully either the repairs for this issue were already done or there was never a problem to begin with.
