Remy 12894 alternator for the 2007-2008 BMW Alpina B7 V8 4.4L and other vehicles charges the battery and powers the electrical system while the engine runs. This remanufactured Remy alternator replaces a worn or failed unit.
A battery warning light, dimming headlights or a battery that keeps running flat can mean the alternator is no longer charging. A weak battery, a worn drive belt or corroded battery cable ends can be behind these signs too, so find the cause before buying a new alternator.
This alternator is listed for a wide range of BMW models, including the 2004-2006 BMW X5 V8 4.8L, the 2005-2006 X5 V8 4.4L and the 2004-2005 BMW 545i V8 4.4L. The 2004-2005 BMW 545i V8 4.4L takes one alternator. If your BMW is not named here, look up its year and engine in the "Vehicles it fits" section.
