Check Engine Light Due to Faulty Camshaft Adjuster Solenoid on Mercedes-Benz CLK350

Problem Description and Possible Solution

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

My engine light is on. Codes P1200 and P1208 were read. My car is running rougher than before. Is there a recall on this factory defective balance shaft? What is my recourse? Will MB cover this repair? My mechanic wants $6500. To fix this problem. I have not had any work done yet it makes me sick to think about it. This will be my last Mercedes if the dealership does not cover this inferior part!
My check engine light comes on and goes back off in my Mercedes-Benz 2006 CLK 350. I had it diagnosed and had an oil change and the results from the diagnostic test the mechanic gave me is: Stored Code for Camshaft Acutuator Retarted. The mechanic said that he did not have the machine to fix this. Is this the same thing as Camshaft Adjuster Solenoid failure? Should this be covered under the Master Tech vehicle protection program secure coverage?

I got rid of my Mercedes 2006 CLK 350. I don't want to deal with Mercedes again. They wouldn't own up to their mistakes and made me feel as though they weren't customer friendly.
Sent an email to Mercedes customer care nicely asking if they believe a car with less than 34,000 miles on it should have this type of major mechanical flaw and if they will take responsibility for fixing it. No response of any type. Guess they don't really care about customer satisfaction. I will probably have to bite the bullet and get this fixed. I can promise you this is my 2nd and LAST Mercedes Benz.
If there is an ongoing class action suit related to this, I would be interested in adding my name.
Light came on and I had to pass emmissions. I changed the oil, oil and air fillers but nothing seemed to work. Took it to Mercedes and I was told it would be about $7,000 to fix it. This car is in great condition but I'm not spending $7,000 on a 10 year old car that won't retail for much more than that.
My transmission went out at 6 months brand new, my rear end differential went out at 60,000 which cost me almost $3,000 and now this problem with the cam shaft which will cost $7,000. This car was a lemon from the start and I need some help. Mercedes would not stand by their product when all this happened. Who can help me?
Not fixed yet. One of four sensors (?) confirmed throwing error. Dealer recommend changing all four for $600+.
check engine light on. cam shaft problem and it will cause roughly 6,000 dollars to get fixed. it stalls while driving
while at mecedes dealer,the check engine light came on. the tech.checked the code and it came as 1208. they told me the the cam shaft and gear need to be replaced. the cost given to me is 5,714.15
intermittent check engine light coming on,no faults detectable when driving but fault code for left exhaust camshaft sensor is can be cleared but will return after a while,the sensor signal from both exhaust camshaft sensors look exactly the same when viewed on an scope.susspect the camshaft adjuster solenoid may be faulty although the camshaft deg match both exhaust cams when testing
