I took my car in for service at a BMW "expert" here in Port Elizabeth ,South Africa when it was not starting. They kept it for 9 months and when i took it last week, it now starts but the lights fade in and out. I bought a new battery but it became very hot and boiled over so I had to buy another one. The indicators are not working and the i have to use the manual key to open the car. PLEASE HELP WITH WHAT COULD BE WRONG as it seems there is no competence here in Port Elizabeth
