Hi there, I saw your post regarding wiring U.S. to European tail lights and I have actually just received European style tail lights by accident but would like to make them work as I think it’s the only type that supports sequential on the 2015 C300.

Perhaps you could help with what you did to accomplish wiring it in. My plug was slightly different so I clipped the extra small plastic tab, plugged it in and now get a turn signal error along with the amber staying lit with head lights engaged, and blinker only effects the red element. Could you please help me program/rewire mine to European version? I would be forever grateful, thanks!
