Application and Buying Notes

Before ordering, match the part number 1986S00817, the 12V rating, the 10 tooth count, and the CW rotation to the starter being replaced. Those are the key identifiers on this Bosch unit and should be compared with the original starter or the vehicle application listing used for the job.

The fitment information provided includes Porsche Cayenne applications, with sample model years from 2007 through 2010. If your vehicle is outside those applications, or if the original starter differs in tooth count, rotation, or mounting bore arrangement, the safest approach is to confirm the exact replacement by part number and application details before purchase.

The stated Bosch features focus on OE-style fit, premium starting performance, and durability in harsh environments. That makes the unit suitable where a like-for-like replacement is required, but the correct application still depends on matching the electrical and mechanical details rather than relying on the badge alone.

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 1986S00817 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.
