Application and Buying Notes

Before ordering, match the part number 1986S00870 and confirm the starter’s 12V specification, 13 tooth pinion, and CCW rotation against the vehicle’s existing unit. Those details matter as much as the badge on the car, especially where multiple starter variants are used across similar models.

Also compare the mounting and physical dimensions: 3 hole mount type, 2 mounting bores, 127mm mount centres A, 111mm mount centres B, 18mm mount centres C, 79mm flange diameter, 247mm overall length, 34mm pinion diameter, and 12.5mm mount hole diameter. A starter can look close and still be wrong if any of these points differ.

The listed application groups cover Audi, Skoda and Volkswagen models, including A1, A3, Karoq, Kodiaq, Octavia, Caddy, Golf, Jetta, Passat, Polo, Tiguan, Transporter and related variants. Use the exact vehicle details and the original starter’s measurements to confirm fitment before purchase.

If you are replacing a failed starter, it is worth checking the old unit for the Bosch marking, tooth count, rotation direction and mount style before fitting. The starter is a rotating electrical component, so correct identification up front helps avoid downtime and unnecessary returns.

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 1986S00870 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 1986S00870, 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.
