It uses an internal regulator and a pad mount with direct fastening, so the physical mounting style and electrical setup need to match the vehicle application before purchase.\u003c\/p\u003e\n\u003cp\u003eThis unit is specified as an alternator type excluding vacuum pump, with a 6 groove pulley and a free-wheel belt pulley fitted. The pulley outside diameter is 49 mm, and the mount leg thickness is 63 mm. Those dimensions matter when checking the drive layout and mounting arrangement against the existing unit.\u003c\/p\u003e\n\u003cp\u003eBosch lists this alternator as manufactured in Hungary and covered by a one year warranty. It is supplied as an each unit and is identified in the rotating electrical product group, which is useful when cross-checking the replacement against the vehicle’s original charging system parts.\u003c\/p\u003e\n\u003cp\u003eThe listed features focus on durability and stable operation: quality raw materials, corrosion resistance, and a reduction drive intended to maintain continual speeds for easier starting. As with any alternator replacement, the key is matching the part number, mounting style, pulley setup, and electrical rating rather than relying on appearance alone.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator with 180A charge current\u003c\/li\u003e\n\u003cli\u003eNew unit with internal regulator\u003c\/li\u003e\n\u003cli\u003ePad mount with direct fastening\u003c\/li\u003e\n\u003cli\u003e6 groove pulley with free-wheel belt pulley\u003c\/li\u003e\n\u003cli\u003eAlternator type excludes vacuum pump\u003c\/li\u003e\n\u003cli\u003eOne year warranty\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\u003ePart number: 0121715112\u003c\/li\u003e\n\u003cli\u003ePower rating: 180 amp\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003cli\u003eMount type: Pad\u003c\/li\u003e\n\u003cli\u003eFastening type: Direct fastening\u003c\/li\u003e\n\u003cli\u003ePulley outside diameter: 49 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment information supplied\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 1 series applications are listed in the fitment data, including model years 2007, 2008, 2009, 2010, 2011, 2012 and 2013.\u003c\/li\u003e\n\u003cli\u003eBMW 3 series applications are listed in the fitment data, including model years 2004, 2005 and 2006.\u003c\/li\u003e\n\u003cli\u003eBMW 5 series, BMW X1, BMW X3 and BMW X5 are listed in the fitment data.\u003c\/li\u003e\n\u003cli\u003eFitment is vehicle-specific and must be checked against the existing alternator part number, mounting style and pulley details before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eWhen replacing an alternator, the most reliable check is the part number 0121715112 together with the mounting and pulley details. This Bosch unit is a 12V, 180A alternator with an internal regulator, a pad mount, direct fastening, and a 6 groove free-wheel belt pulley, so all of those points should line up with the vehicle’s original component.\u003c\/p\u003e\n\u003cp\u003eThe alternator is specified as excluding a vacuum pump. That matters on applications where the original unit includes different rear housing or accessory arrangements. The 49 mm pulley outside diameter and 63 mm mount leg thickness are also useful checks when comparing the replacement to the removed part.\u003c\/p\u003e\n\u003cp\u003eBosch recommends additional repairs to the V-belt or V-ribbed belt. That is practical advice during alternator replacement because belt condition and tension can affect charging performance, noise and drive stability. If the belt shows wear, glazing or cracking, it is sensible to address it at the same time.\u003c\/p\u003e\n\u003cp\u003eThe listed fitment points toward several BMW applications, including 1 series, 3 series, 5 series, X1, X3 and X5 entries. Even so, vehicle fitment should never be assumed from the badge alone. Confirm the charging system layout, pulley groove count, mounting style and existing alternator number before finalising the order.\u003c\/p\u003e\n\u003cp\u003eIf you are working from a removed part, compare the old and new alternator side by side before installation. The key identifiers here are Bosch, 0121715112, 12V, 180A, internal regulator, pad mount, direct fastening, and 6 groove pulley. Those details are the best way to avoid a mismatch and save time at fitting.\u003c\/p\u003e\n\u003cp\u003eThis alternator is a new unit, not remanufactured, and Bosch lists a one year warranty. For workshop use or a customer repair, that gives a clear baseline for supply, but it does not replace the need to confirm the vehicle application and the physical dimensions against the original alternator.\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 0121715112 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, Unit of Measure EACH, Warranty One Year, Pin Code IR168, Pulley Outside Diameter 49mm, Regulator Type Internal, Voltage 12, New \/ Reman.
