E220 2005 Side Mirror indication failure warning. Installed new but no luck. HELP

[CDI-E220-2005]

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.
