It’s not my day.
Few days ago my door Handel stopped working, its just work from inside the car so with the tips of some friends I removed the door panel and disconnect the airbag and start checking I found my door handle mechanism only need to be changed nothing else. It was late so I left it for next day also I can get the part from BMWSEVICECENTER. But what happen the next morning when I went to open the car I found my battery was flat no life not even to open the central lock with my remote key so I used my key, and nothing happen the only thing I can see is my door lock is opening but I cant use my f*** handle . my tears nearly came out and I don’t want my nosey neighbor to see me stuck . I need your help guys what can I do?
