This Bosch starter motor is a 12V unit with 10 teeth, counter-clockwise rotation, and a 2.0kW power rating. It is listed as new, carries part number 1986S00804, and suits a Bosch unit application. The starter uses a 2-hole mount type with 111mm mount centres and a 76mm flange diameter, so those dimensions are worth checking against the removed unit before ordering.

The starter has 2 mounting bores with 12mm mount hole diameter, and it is supplied as a single each item.

Bosch describes the unit as designed to withstand harsh environments and to match OE starter fit and performance. It is manufactured in Hungary and comes with a 12 month warranty. For customers replacing an existing Bosch starter, the part number 1986S00804 and the listed dimensions provide the most reliable confirmation points before purchase.

Application and Buying Notes

The safest way to buy this starter is to match the existing unit by part number, mounting pattern, and electrical specification. This Bosch unit is 12V, 10 tooth, CCW, and uses a 2-hole mount with 111mm mount centres, so those details should line up with the starter being replaced.

The listed dimensions matter because starter motors can differ even within the same vehicle family. The 76mm flange diameter, 242mm overall length, 27mm pinion diameter, and 62mm pinion at rest measurement give you useful checkpoints when comparing the old unit, especially if the vehicle has had previous repairs or non-original parts fitted.

If you are buying for an Audi, Skoda, or Volkswagen application, use the fitment list as a guide only and still confirm against the original starter. The fitment data includes Audi A3 and TT, Skoda Octavia, Roomster, Superb, and Yeti, plus Volkswagen EOS, Golf, Jetta, Multivan, Passat, Polo, Transporter, and Transporter / Caravelle applications, but final confirmation should always be made from the physical unit and part number 1986S00804.

This is a new Bosch starter motor with a 12 month warranty, so it is suitable where a replacement new unit is preferred over remanufactured stock. The unit is manufactured in Hungary, and the product is supplied individually as each, which is the normal format for a starter replacement order.

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 1986S00804 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 1986S00804, 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.

Available application references include AUDI A3, AUDI A3 2003, AUDI A3 2004, AUDI A3 2005, SKODA OCTAVIA, SKODA OCTAVIA 2004. 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.

Compatibility note: Please confirm compatibility using the original part number 1986S00804, the 12V electrical rating, CCW rotation, 10 tooth pinion, 2-hole mounting pattern, and the measured dimensions before purchase. Vehicle fitment should always be checked against the removed starter and application details, as matching model names alone is not enough for starter motor selection.
