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?

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.

Check engine light goes off and on checked and gave codes P2006 & P0024
intermittent check engine light coming on,no faults detectable when driving but fault code for left exhaust camshaft sensor is recorded.it 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
