Bosch Alternator 12V 180A 0121715176

This Bosch alternator is a 12V, 180A unit with part number 0121715176, supplied new and built with an internal regulator. It suits Bosch applications and is listed as an alternator type excluding vacuum pump, so it is important to match both the part number and the physical mounting details before ordering.

The unit uses a quad leg alternator mount, with inside mounting legs of 60mm and a mount centre to centre measurement of 128mm. The pivot hole diameter is M8x1.25 / 8.5, and the adjusting hole diameter is also M8x1.25 / 8.5. Those dimensions are the sort of details that can save time when you are confirming whether an alternator will physically sit correctly in the vehicle.

It is fitted with a multi-belt pulley with 6 grooves, a pulley outside diameter of 56mm, and clockwise rotation. The alternator weighs 7.52kg and is packaged at 23.9 length and 20 height, so it is a substantial rotating electrical component rather than a small universal replacement. The stated warranty is one year.

Application and Buying Notes

When matching this alternator, the most important checks are the part number 0121715176, the Bosch brand, and the mounting and pulley details. The unit is 12V and rated at 180A, so it should only be considered where that voltage and charge output are correct for the application. A 6-groove multi-belt pulley with a 56mm outside diameter is another key checkpoint, because pulley style and belt alignment need to match the existing setup.

The physical dimensions are equally important. This alternator has a quad leg mount, 60mm inside mounting legs, a 128mm mount centre to centre measurement, and M8x1.25 / 8.5 pivot and adjusting holes. Those measurements are useful when comparing against the removed unit, especially where the alternator bracket and tensioning arrangement must line up exactly.

Because this unit is listed as excluding vacuum pump, it should not be treated as a general substitute for alternators with a vacuum pump arrangement. The internal regulator is also part of the specification, so the vehicle’s charging system needs to be compatible with that style. If the old alternator is available, compare the shape, mounting points, pulley grooves, rotation direction, and connector arrangement before fitting.

The supplied fitment data references Audi A4, Audi A6, Audi A6 Allroad and Audi Q7 applications, but fitment should still be checked carefully against the exact vehicle details. Alternators can vary by engine, charging setup, bracket style and accessory drive configuration, even within the same model range. A quick comparison of the part number and mounting measurements is the safest way to avoid a mismatch.

This is a new Bosch rotating electrical component with a stated one year warranty, weighing 7.52kg. If the vehicle is being repaired for a charging fault, it is still worth confirming the battery condition, belt condition and any wiring or charging circuit issues before installation. An alternator alone will not resolve every charging concern if the rest of the system is not in order.

Before 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.

For workshop, fleet, and equipment applications, accurate identification of part number 0121715176 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.
