Application and Buying Notes

For a starter motor, the most important checks are part number, rotation, voltage, and mounting layout. This Bosch unit is 12V, clockwise rotating, and has 2 mounting bores, so it should only be considered where those details match the original starter and vehicle application.

The supplied fitment data includes Porsche Cayenne applications for 2007, 2008, 2009, and 2010, but the safest way to confirm suitability is still to compare the original unit against Bosch part number 1986S00816. Starter motors can look similar while differing in rotation, mounting pattern, or internal configuration.

The stated OE-style fit and performance, plus the 12 months warranty, give a useful reference point for buyers who want a direct replacement approach. Even so, it is still important to verify the existing starter’s markings, mounting bores, and electrical setup before purchase, especially on vehicles where multiple starter versions may be listed across different build dates or engine combinations.

Packaging dimensions are also provided for handling and freight planning: 32.5 cm by 18 cm by 13.9 cm. Those measurements do not confirm fitment, but they are practical when checking storage space, dispatch requirements, or whether the part can be conveniently collected or transported.

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 1986S00816 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.

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 PORSCHE CAYENNE, PORSCHE CAYENNE 2007, PORSCHE CAYENNE 2008, PORSCHE CAYENNE 2009. 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.
