Application and Buying Notes

When replacing a starter motor, the part number and physical mounting details matter just as much as the vehicle make. This unit is Bosch 1986S00805, with a 12V electrical setup, 11 teeth, CCW rotation, and a 2 hole mounting pattern. Those details should be matched carefully against the original unit already fitted to the vehicle.

The dimensions are specific enough to check against the failed starter before ordering: 250mm overall length, 79mm flange diameter, 11mm mount hole diameter, 119mm mount centre to centre, 28mm pinion diameter, and 42mm pinion at rest. If any of those measurements differ from the existing starter, the unit may not suit the application even if the vehicle family appears in the fitment list.

This starter motor is listed as a dry clutch type, so that is another useful checkpoint where the vehicle setup or existing component specification needs to be confirmed. For workshop or driveway replacement jobs, comparing the old starter side by side is often the safest way to confirm the mounting style, tooth count, rotation direction and physical clearance before installation.

Bosch identifies this as an OE-standard product with optimised internals for starting cycles and service life, and it carries a 12 month warranty. Even so, starter motor complaints can also come from battery condition, charging issues, poor cables, earth faults or engine-related concerns, so it is worth confirming the wider starting system is healthy before fitting a replacement part.

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 1986S00805 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 12 Months, Mount Hole Diameter 11, Overall Length 250mm, Pinion Diameter 28mm, Rotation CCW, Mount Cnt to Cnt 119mm, Wet / Dry Clutch Dry, Packaging length 32.5.

Additional published details for cross-checking include Packaging height 13.9, Product Group 2 STARTER MOTORS, Part No. 1986S00805, Brand BOSCH, Description Bosch Starter Motor 12V 11Th CCW, Flange Diameter 79mm, Number of Teeth 11, Pinion at Rest 42mm, Power Rating 2.0kW.

Bosch Starter Motor 12V 11Th CCW. Part number 1986S00805 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S00805, 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 2012, AUDI A3 2013, AUDI A3 2014, SKODA KODIAQ, SKODA KODIAQ 2016. 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 fitment using Bosch part number 1986S00805 together with the 12V, 11 tooth, CCW, 2 hole mounting and dimension details before ordering.
