The 439261 is identified with technical number SG9B011 and is built as a 100% new unit, which helps avoid the wear concerns associated with reused internal components. It is a direct replacement choice for drivers searching for a 2000-2005 Volkswagen Passat alternator, a 2000-2001 Audi A4 alternator, or a 2002-2004 Audi Allroad Quattro charging system replacement. This part cross-references Bosch AL0725X for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBattery warning light caused by weak charging output\u003c\/li\u003e\n\u003cli\u003eLow system voltage affecting lights, accessories, or electronics\u003c\/li\u003e\n\u003cli\u003eCharging instability from a failing internal regulator\u003c\/li\u003e\n\u003cli\u003eNoise or belt drive issues related to alternator wear\u003c\/li\u003e\n\u003cli\u003eStarting problems linked to insufficient alternator output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify pulley groove count, rotation direction, amperage rating, and connector match before installation.
