Error U120E - Blind Spot + Collision Inoperative
I receive an error on the tester - U120E - Blind spot and collision prevention assist inoperative. Cannot find anything online about this errorcode.
Do you have any clue what may cause this ? I have changed my front bumper and obviously the computer (radar) in front of the bumper.
I have a c220d 2016 170hp.
Thanks a lot for any suggestions.
