There are tons of components that allow your BMW to be powered up enough to run properly. The part generating electrical power needed for your vehicle to be able to start is your alternator. Your car wouldn't be able to operate effectively without a working alternator. The battery in your vehicle does supply some power to different systems, but it relies on your alternator to recharge it and keep it from dying throughout the day. When a problem happens with the alternator, many assume it's a battery problem at first because the symptoms are similar. Your battery may be dying frequently when your alternator is wearing out. It's important to get both parts tested if this keeps happening to determine what the source of the problem is. Other things you might notice include the indicator lights coming on in your vehicle. It could be an alternator specific warning light, or it could be the battery light. Your car might also stall or struggle to start. We have the best OEM genuine alternators, but at a fraction of the cost. We also have them for many BMW models so you can find the right part for your specific car.
