If your battery cables have become worn or frayed, or the IBS sensor has gone bad, its time for a replacement. BMW use the IBS, or Intelligent Battery Sensor, to determine not only the state of charge but also the batteries health and life expectancy. Using this data the car's charging system can appropriately supply the battery with the correct voltage, no matter the age.
Comes as a single cable with terminal and IBS Sensor pre-installed.
The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.
This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!
