The factory-installed car starter or starter motor in your BMW gets called everything from a self-starter to a cranking motor. Whether yours is remanufactured or new, what an original starter does is as the name suggests. A simple, small, car battery-powered motor, it sends power through a starter relay to start your engine. A remote starter takes care of this without a key turn, with the press of a button on a smart key fob. When nothing happens, however, it's usually because you've got a bad starter. Loose or dirty wires, battery rust, or damaged or degraded parts are often the causes. However, signs of a bad starter are plenty. They include a lit dash without any engine power, no engine rev even after jump-starting, visible smoke, and an oil-covered starter. You might also be able to start your BMW in some drive modes or gears and not others if you can turn the engine at all. The former can mean a bad neutral safety switch. The best fix for a failed starter is to install a genuine starter, direct from BMW. That's because OEM starters are built according to make and model for a guaranteed fit.
