5 Signs Your BMW Needs a New Alternator

 

5 Signs Your BMW Needs a New AlternatorThe alternator plays a very important role in your BMW. The alternator is connected to the belt system in the engine and the rotary motion of the motor causes the alternator to spin, which allows it to produce electricity. This electricity is used for a variety of functions while the vehicle is turned on, such as operating electrical accessories like power windows and locks and the radio. However it also supplies the electricity to the spark plugs to ensure a proper running engine. Additional electrical power created by the alternator is stored in the battery for use when the car is not on and to get the car started. If the alternator fails you'll run into many problems, including a car that won't start. Pay attention for these signs of possible BMW alternator failure so you can have it replaced before it's too late.

Dim headlights

The alternator is what supplies electricity to the headlights while the vehicle is turned on. If the headlight seen dim or flicker on and off while in use it may be caused by a failing alternator that cannot provide the headlights with the proper amount of electrical juice.

Hard starting or stalling

Since the alternator is what provides the electrical power necessary for the spark plugs to ignite the air and fuel mixture your engine uses to run your vehicle may stall or have a hard time starting if the alternator begins to fail. The vehicle may stall while in motion, or while stopped. Hard starting is characterized by excessive engine cranking.

Battery dies

Perhaps one of the most obvious signs of alternator failure is a battery that dies. If the battery dies and you are positive that you did not leave the lights on, a door ajar or leave on any other accessory that may drain power while you are away from the vehicle while it is turned off for some amount of time it is likely due to an alternator that is not producing electrical power.

Electrical failures

The alternator provide electrical power to numerous other systems in your BMW, as previously mentioned these include power windows and locks, the radio, infotainment systems, power seats and more. If any of the systems, or all of them, seem to no longer work it may be related to a failed alternator. This will soon be followed by a vehicle that won't start.
