Application and Buying Notes

Before ordering, match the part number BXS4012, the 12V rating, clockwise rotation, and the Bosch style specification to the starter being replaced. Those details matter just as much as vehicle model because the same family of vehicles can use different starter setups depending on engine and application.

The 13 tooth pinion and 3 hole mounting pattern are important checkpoints, along with the listed 120mm mount centres A, 84mm mount centres C, 62mm flange diameter, and M10x1.5 mount hole diameter. If the old unit differs in these dimensions, the replacement should be checked carefully before fitting.

This is a new starter motor with a 1.2kW power rating and dry clutch arrangement, so it is intended to be installed as a direct electrical and mechanical replacement where the application matches. The supplied warranty is 3 years for passenger use and 1 year for commercial use, which is another reason to keep the installation and intended vehicle use aligned with the product listing.

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 BXS4012 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 BXS4012, 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 CITROEN BX, CITROEN C4, CITROEN C4 2004, CITROEN C4 2005, PEUGEOT 205, PEUGEOT 206. 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 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using the BXS4012 part number, 12V CW specification, Bosch style application, and all listed mounting and pinion dimensions before purchase.
