Hello there. I have a w211 e220 2005. The passenger side mirror's indicator failed. i had a warning message saying LEFT SIDE INDICATOR FAIL etc. The indicator was broke, glass was cracked so i went to mercedes and got new LED indicator same as the original one installed. Now i have installed it i am still getting the same message and it doesnt work. i have checked all wiring and no wires seems to be damaged from anywhere. I have researched on the net but no luck. Is there any fuse which i can check or anything else that i should try. please help. its driving me mad.
