Bosch Starter Motor 12V 13TH CCW 1986S00851

The Bosch Starter Motor 12V 13Th CCW, part number 1986S00851, is a rotating electrical component supplied as a single each unit. It is listed with 2 mounting bores and a 12 month warranty, which makes the part number and mounting details important checkpoints when matching it to the vehicle application.

This starter motor is described as suitable for an Audi A3 with a CAXC engine and automatic transmission. That application detail matters, because starter motor fitment can vary by engine code, transmission type, and mounting arrangement even when the vehicle badge is the same.

The unit is identified as Bosch and is manufactured in China. Packaging dimensions are listed as 32.5 length, 13.9 height, and 18 width, which may be useful when checking freight handling or workshop storage before installation.

Application and Buying Notes

Before ordering, confirm the part number 1986S00851 against the old starter motor and compare the mounting arrangement, since this unit has 2 mounting bores and is listed as 13Th CCW. The engine code and transmission type are both relevant here, with the verified application limited to Audi A3 vehicles with the CAXC engine and automatic transmission.

If you are replacing a starter on an Audi A3, check the engine code on the vehicle identification label or service documentation rather than relying on the badge alone. A3 models can be built with different engines and drivetrains, and the starter motor application depends on those details as well as the physical fitment points.

The 12V rating should match the vehicle’s electrical system, and the listed Bosch configuration should be matched carefully before installation. If the existing starter motor has different mounting bores, a different rotation/configuration, or a different part number, it should be treated as a separate application until confirmed otherwise.

Packaging dimensions are 32.5 by 13.9 by 18, which does not affect fitment but can help with delivery planning and workshop handling. For the cleanest result, compare the old unit, the part number, and the vehicle application details together before purchase.

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 1986S00851 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 1986S00851, 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 electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A1, AUDI A1 2010, AUDI A1 2011, AUDI A1 2012, VOLKSWAGEN GOLF, VOLKSWAGEN GOLF 2008. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 1986S00851, engine code CAXC, automatic transmission, and the 2-mounting-bore starter configuration before ordering.
