Over time, brush wear, diode bridge breakdown, and internal voltage regulator failure lead to excessive ripple voltage, erratic electrical cutouts, and premature battery starvation. Bearing degradation also induces front-drive whine and parasitic drag along the serpentine drive belt routing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eBuilt to direct OEM physical standards, this brand-new 140-amp charging unit features heavy-duty insulated copper stator windings, a high-speed precision dynamically balanced rotor, and dual-sealed heavy-duty bearings for thermal endurance. An internal solid-state voltage regulator maintains a steady 13.5V to 14.5V output under total accessory load. Featuring a matched 5-groove clockwise (CW) serpentine pulley, direct-fit casing mounting ears, and a factory-matched pin plug harness terminal, it installs directly with zero wiring splices or bracket modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Replacement 140-Amp 12V Alternator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2005-2011 Volkswagen Jetta 2.5L\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2.5L I5 (BGP\/BGQ\/CBTA\/CBUA) \/ Mk5 (A5) \u0026amp; Mk6\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e150-170 hp \/ 170-177 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e11254, 07K-903-023A, 0-124-525-062, 0-124-525-102\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2010 Volkswagen Jetta (Mk5) 2.5L 5-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2011 Volkswagen Jetta (Mk6) 2.5L 5-Cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Mk5 and Mk6 Jetta?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2011 Volkswagen Jetta equipped with the \u003cstrong\u003e2.5L inline-5 (EA855)\u003c\/strong\u003e engine; it does not fit 2.0T FSI\/TSI, 1.9L\/2.0L TDI, or 2.0L naturally aspirated models.\u003c\/p\u003e\n\n\u003ch4\u003eShould the battery be fully charged before installing the new alternator?\u003c\/h4\u003e\n\u003cp\u003eYes, always bench-charge your battery completely before starting the engine to prevent overworking the internal voltage regulator during initial startup.\u003c\/p\u003e\n\n\u003ch3\u003eThe Volkswagen Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to satisfy stringent European onboard diagnostics, this unit delivers pure, ripple-free direct current to eliminate low-voltage CAN-bus fault codes and safeguard sensitive VAG control modules.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898426294520,"sku":"DS-EBLHMVORI","price":105.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/alternator-for-volkswagen-jetta-2005-2011-2-5l-1.jpg?v=1793321013","url":"https:\/\/performancechiptuning.com\/es\/products\/alternator-for-volkswagen-jetta-2005-2011-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
