it should fit, but as for the srs airbag connection I dont know if its the same, and you will need the airbag with the steerign wheel too.
the W203 has steering wheel controls (multi-function controls) that will not work with your W202.
so everything will be for looks! if the airbag connections are the same.
anyone else know if the airbag connections are the same for W203 and W202 pre-updated?
