It is described as an alternator passenger type, with direct fastening and an alternator type of excl. vacuum pump, so matching the application correctly is important before purchase.\u003c\/p\u003e\n\u003cp\u003eWith a 150 amp power rating and 150 amp alternator charge current, this unit is aimed at vehicles that require the same electrical output and mounting arrangement. The recommended additional repair is a V-belt\/V-ribbed belt, which should be checked at the same time if the charging system service is being completed properly.\u003c\/p\u003e\n\u003cp\u003eBosch identifies this part as belonging to the rotating electrical product group, and it comes with a 12 month warranty. It is a single unit sold each, which makes it suitable for direct replacement where the part number and application details line up with the vehicle.\u003c\/p\u003e\n\u003cp\u003eThe listed features include quality raw materials for long life, corrosion resistance for harsh conditions, and a reduction drive designed to maintain continual speeds for easier starting. Those are useful practical points, but the key buying checks remain the 12V system, 150A output, direct fastening, and the vacuum pump exclusion.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator, 150A output\u003c\/li\u003e\n\u003cli\u003eBosch part number 1986A01039\u003c\/li\u003e\n\u003cli\u003eDirect fastening mounting type\u003c\/li\u003e\n\u003cli\u003eAlternator type: excl. vacuum pump\u003c\/li\u003e\n\u003cli\u003eRecommended additional repair: V-belt\/V-ribbed belt\u003c\/li\u003e\n\u003cli\u003eSold as each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Bosch\u003c\/li\u003e\n\u003cli\u003eType: Alternator passenger\u003c\/li\u003e\n\u003cli\u003ePower rating: 150 amp\u003c\/li\u003e\n\u003cli\u003eAlternator charge current: 150A\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003ePart No.: 1986A01039\u003c\/li\u003e\n\u003cli\u003eFastening type: Direct fastening\u003c\/li\u003e\n\u003cli\u003eAlternator type: excl. vacuum pump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChecked application details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAudi A4 applications are listed in the fitment data, including model years 2008 through 2015.\u003c\/li\u003e\n\u003cli\u003eAudi A5 applications are listed in the fitment data, including model years 2007 and 2008 in the sample preview.\u003c\/li\u003e\n\u003cli\u003eAudi Q5 is listed in the fitment makes data.\u003c\/li\u003e\n\u003cli\u003eFitment should still be confirmed against the part number 1986A01039, the 12V 150A output, direct fastening, and the excl. vacuum pump alternator type before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore buying, confirm that your vehicle uses a 12V charging system and that the alternator required is rated at 150A or 150 amp charge current. Those two values are central to compatibility, and a mismatch can lead to incorrect charging-system performance or the wrong physical replacement.\u003c\/p\u003e\n\u003cp\u003eThe mounting style matters here as much as the electrical rating. This Bosch unit uses direct fastening, so the bracket arrangement and physical fit must match the vehicle. It is also listed as excl. vacuum pump, which is an important separator when comparing alternators that may look similar at a glance.\u003c\/p\u003e\n\u003cp\u003eThe product is sold as each and carries a 12 month warranty. That gives you a clear replacement unit with known output and a defined warranty period, but it does not remove the need to verify the application details against your existing part and vehicle build.\u003c\/p\u003e\n\u003cp\u003eFor the best result, compare the Bosch part number 1986A01039 with the removed unit and check the vehicle’s alternator layout before ordering. If the current alternator has a vacuum pump or uses a different fastening arrangement, this unit may not be the correct match even if the vehicle model name appears similar.\u003c\/p\u003e\n\u003cp\u003eThe listed features around raw material quality, corrosion resistance, and reduction drive are useful build indicators, but they should be treated as supporting details rather than fitment proof. Correct application still comes down to the electrical specification, fastening type, and the exact part number.\u003c\/p\u003e\n\u003cp\u003eBefore supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 1986A01039 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR PASSENGER, Unit of Measure EACH, Warranty 12 Months, Voltage 12, Fastening Type Direct fastening, Recommended additional repairs V-Belt\/V-Ribbed Belt, Product Group 1 ROTATING ELECTRICAL, Part No. 1986A01039, Brand BOSCH, Description Bosch Alternator 12V 150A.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Power Rating (Amp) 150, Alternator Charge Current [A] 150, Alternator Type excl. vacuum pump, Product Group 2 ALTERNATORS.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 150A. Part number 1986A01039 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 1986A01039, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.\u003c\/p\u003e\n\u003cp\u003eFor a alternator passenger in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include AUDI A4, AUDI A4 2008, AUDI A4 2009, AUDI A4 2010.
