Check valve on the m271 motor in my 2005 c230 has a defect allowing the supercharged air to enter into the crankcase of the engine pushing oil into it and it caused a misfire reading, loss of power and the check engine light to go on. The campaign I found identical to my problem is number is 2008020002. However it's repair coverage is only associated with a range of VIN #'s throughout 2003-2005 which my car is a 2005, but the campaign is not listed under my VIN#.

Problem starts with a hesitation upon acceleration and loss of power while driving. After shutting engine off, then upon starting vehicle, engine would start to shake and stumble. Check engine light would come on. Vehicle engine sounds as if it going to blow up and has no power and stalls becomes undriveable. If you shut engine off again and restart sometimes car can be driven even though check engine light remains on. It always shows the same codes for repair. Car has been towed to dealer 2 times and driven over 4 additional times. Each time the code comes up as a coil defect and dealer has replaced coil #2 several times due to coil being burnt along with cleaning and/or replacement of spark plugs only to have the problem recur within hours or days. They still have not been able to correct problem. Dealer gave me same model loaner vehicle which I had to return within hours due to same problems.
