part number and source for W204 headlamp dustcover

[6cyl]

Hi,
Is there an online resource that I can use to find out genuine and oem alternative part numbers ? Where you enter your VIN and then search for the part with a diagram and number ?

I'm looking for the bulb dust cover for the low beam halogen headlamp for a 2010 W204.

Would the local dealer be the best place to get them from ?

Thanks.
