Application and Buying Notes

Before ordering, compare the Bosch part number 1986S00725 with the number on the starter being replaced. That is the most reliable first check, especially when the vehicle range includes Audi A4 and Audi A6 references across multiple model years. Even when the make and model look close, starter motors can differ by mounting arrangement, rotation, and electrical specification.

The listed 12V rating and 9th CW description should match the vehicle’s original starter requirements. The unit has 2 mounting bores, so the mounting pattern matters just as much as the brand name or vehicle badge. If the replacement starter has a different bore arrangement or orientation, it may not suit the application even if other details appear similar.

Packaging dimensions may also help if the part needs to be collected, stored, or shipped in limited space. With a 32.5 cm length, 18 cm width, and 13.9 cm height, this is a compact starter assembly, but the important point remains the same: confirm the part number, voltage, rotation detail, and mounting setup before finalising the purchase.

The warranty is listed as 12 months. That gives a defined warranty period for the unit, but it should not be treated as a substitute for fitment verification. The safest approach is to match the application details carefully, especially where Audi A4 and Audi A6 references appear in the known fitment data.

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 1986S00725 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.

Bosch Starter Motor 12V 9Th CW. Part number 1986S00725 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S00725, 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 passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A4, AUDI A4 2004, AUDI A4 2005, AUDI A4 2006. 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.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part no. 1986S00725, 12V specification, 9th CW description, and the 2 mounting bores against the vehicle’s original starter and application details before ordering.
