Has any one reported expensive valve issues in the cylinder head and intake manifold? Is this a common repair? My car is a 2008 and I am experiencing this costly repair $2,500-$6,000
C 300 2008 4 door sedan with 85,000 miles. I am upset that this kind of repair is happening this farily new car. I have maintained this car and only had the car repaired at the Mercedes dealerships! Mercedes Benz says this is a "fluke" and not common with the 2008 C-300. From talking to various repair shops they seem to say the vavlue issue has been a common occurrance as well as the intake manifold. If this is the case shouldn't these items be recalled and Mercedes should fix since it seems it would be a defect?
