Application and Buying Notes

A starter motor needs to match the vehicle’s electrical and mounting requirements, so the key checks here are 12V, 11 teeth, CCW rotation, and the 2 hole mounting pattern. The part number 1986S00803 is the most reliable identifier to confirm before ordering.

Physical dimensions matter just as much as the electrical specification. This unit has an overall length of 255mm, a 76mm flange diameter, a 27.5mm pinion diameter, and 11mm mount holes with 119mm centre-to-centre spacing, so matching the old starter against these measurements is the safest way to avoid a mismatch.

The listed fitment families include Audi A3 and TT, Skoda Octavia and Superb, and Volkswagen Caddy, CC, Eos, Golf, Jetta, and Passat. Even within those families, the correct starter can vary, so confirm the vehicle application details against the part number and mounting layout before purchase.

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 1986S00803 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 1986S00803, 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.

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: Please confirm compatibility by matching part number 1986S00803, 12V electrical specification, 11-tooth CCW configuration, and the 2 hole mounting pattern against the existing unit and vehicle application details.
