RE: Hi there. New to the forum and seeking advice
The early W203 four cylinder cars used the M111 cast iron block engine. After about May 2002 they started using the M271 aluminum block engine. The new engine has balance shafts and is a lot smoother. It also pollutes less and gets 7% better gas mileage than the M111.
