For buyers matching a replacement starter, the main identifiers to check are the 12 volt rating, 10-tooth drive, CW rotation, and the Bosch part number 1986S00704. Those details matter more than appearance alone when comparing starter motors for the same vehicle.

Application and Buying Notes

When replacing a starter motor, confirm the vehicle uses a 12V system and that the original unit matches the 10 tooth, clockwise configuration. Those three points, together with Bosch part number 1986S00704, are the most useful checks for narrowing the correct replacement.

The fitment preview supplied here points to Audi applications, including A4, A6, A6 Allroad and A8 entries. That is useful as a guide, but the final decision should still be made against the vehicle application and the part number rather than relying on model name alone.

Starter motors are not usually chosen by appearance. A unit can look similar while differing in tooth count, rotation direction or electrical rating. Checking the 12V marking, CW rotation and 10 tooth count helps reduce the risk of ordering the wrong part.

The warranty period for this starter motor is 12 months. That gives a clear time frame for normal warranty coverage, but it does not replace the need to confirm compatibility before installation. Once fitted, any diagnosis should still consider the vehicle’s charging, battery and starting system condition as part of the overall repair.

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 1986S00704 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 1986S00704, 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 2005, AUDI A4 2006, AUDI A4 2007. 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 1986S00704, the 12V rating, 10 tooth count and CW rotation against the vehicle application before purchasing.
