Application and Buying Notes

Before ordering, compare the part number 1986S00788 and OEM number 02M911023G with the existing starter on the vehicle. The key physical match points here are the 12V system, 1.1kW rating, 10 teeth, CCW rotation, and the 2-hole mount layout with 12.5mm mount hole diameter.

The listed dimensions also matter. This starter measures 210mm overall, has a 76mm flange diameter, and a 62mm pinion at rest. If the replacement starter differs in these areas, installation may not be correct even if the vehicle family appears similar.

The fitment list provided covers selected Audi, Skoda, and Volkswagen applications, including A3, Octavia, EOS and Golf families. Vehicle year ranges are not fully stated for every model here, so it is best to confirm the application against the vehicle identification details already fitted to the car.

Bosch describes this unit as designed in fit and performance to meet OE starters and built for harsh environments. Those are useful indicators of intended application, but the final check should still be the exact part number, OEM reference, and the mounting and tooth count on the original unit.

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 1986S00788 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.
