Application and Buying Notes

The most important checks on this starter are the 12V electrical requirement, the 9 tooth pinion, clockwise rotation, and the 2 hole mounting pattern with 111mm mount centre to centre. If any of those details differ from the existing starter, the part may not be suitable even if the vehicle make or model appears similar.

The physical dimensions also matter. The starter measures 204mm overall, has an 82.5mm flange diameter, a 25mm pinion diameter, and a pinion at rest of 14mm. Those measurements help when comparing against the original unit during replacement.

This is a new Bosch starter motor, not a remanufactured unit, and it carries a 12 month warranty. The dry clutch design and 1.1kW rating are part of the specification, so they should be matched with the vehicle’s original starter requirements rather than assumed to be interchangeable with every Bosch starter.

If you are working from a removed starter, check the part number 1986S00670, the mounting bore count, the M12x1.75 mount hole diameter, and the rotation direction. These are the practical details that usually prevent guesswork and save time at fitting.

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 1986S00670 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 1986S00670, 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 A4, AUDI A4 2001, AUDI A4 2002, AUDI A4 2003, VOLKSWAGEN PASSAT, VOLKSWAGEN PASSAT 2000. 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 part number 1986S00670, the 12V specification, 9 tooth clockwise configuration, and the listed Audi A4 or Volkswagen Passat application details before purchase.
