The W212 with HID lighting come with LED bars that are daytime running lights (DRL). They DO NOT come with foglights.
The W212 with halogen lighting come with two conventional lights on each side, one is a DRL and one is a foglight.
Should be fairly easy to replace one with the other, but you'll wind up with a light switch with a foglight postion with nothing to do and some left over wiring.
