2002 was the year inwhich the model changed from x230 to x244. The model is more impotant than the year, when searching for the desired information.
While the x244 is often referred to as a facelifted version of the x230, but the dashboard is considerably different, as is the electrical installation.
The model number may be determined from the VIN either ZFA230xxxxxxx, or ZFA240xxxxxx.
