The Bosch Starter Motor 12V 10T CW is a rotating electrical component supplied as a starter motor for applications that match the listed part number 1986S00748.

This starter motor has 2 mounting bores and is sold as each. Bosch lists it as designed in fit and performance to meet OE starters, with premium starting performance and construction intended to withstand harsh environments. Those are useful indicators, but the correct application still needs to line up with the vehicle details and the part number.

The fitment data includes model-year references in the supplied application list, so it is worth checking the exact vehicle match carefully against the part number 1986S00748 rather than relying on model name alone.

Application and Buying Notes

When comparing this Bosch starter motor, the most important checks are the 12V rating, 10-tooth drive, clockwise rotation, and the 2 mounting bores. Those details must align with the vehicle and the removed part before you commit to purchase, because starter motors can differ in tooth count, rotation and mounting layout even within the same model family.

The supplied fitment references cover Audi and Porsche applications, including Audi A4, A5, A6, A6 Allroad, A7, A8 and Q5, along with Porsche Macan. Model names alone are not enough for a reliable match, so use the part number 1986S00748 and compare the vehicle application carefully, especially where multiple starter configurations may have been used across different years or engine variants.

Bosch identifies this unit as designed to meet OE starters in fit and performance, which is relevant when you want a direct replacement style of component. The 12-month warranty applies to the part as supplied, but warranty cover does not replace the need to verify suitability before installation. For any starter motor, the safest approach is to confirm the original unit’s mounting, electrical specification and drive count before ordering.

If you are replacing a starter motor on an Audi or Porsche application, check the removed starter against the listed specifications rather than assuming a visual match. The packaging dimensions of 32.5 x 18 x 13.9 may also be useful when planning storage or freight handling, but they do not confirm compatibility. The deciding factor remains the application detail and part number match.

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 1986S00748 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.

For part number 1986S00748, 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.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
