OEX Starter Motor 12V 15 Tooth CW Denso Style DXS4055

The OEX starter motor DXS4055 is a new 12V starter motor with 15 teeth, clockwise rotation, and a 2.0kW power rating. It is listed as a Denso style unit and suits Denso applications, with a 3-hole starter mount type and an overall length of 250mm.

Key dimensions matter with starter motors, and this unit has mount centres of 104mm, 101mm and 24mm, a flange diameter of 76mm, and an M10x1.5 / 11 mount hole diameter. The pinion measures 45mm in diameter and sits 26mm at rest, so matching the physical layout is just as important as matching the electrical specification.

This starter motor is noted for start/stop applications and is supplied as a new rotating electrical part. The listed weight is 4.46kg, and the unit of measure is each. For buyers comparing options, the part number DXS4055 and the 12V, 15-tooth, CW specification are the main identifiers to confirm before ordering.

Application and Buying Notes

Before ordering, compare the part number DXS4055, the 12V rating, 15 teeth, and clockwise rotation with the starter you are replacing. Those identifiers are the quickest way to avoid a mismatch when the application is similar but the physical or electrical details differ.

The mount layout is also important on this unit. Check the 3-hole mounting pattern, the listed mount centres of 104mm, 101mm and 24mm, and the 76mm flange diameter against the vehicle and the removed starter. The M10x1.5 / 11 mount hole diameter and 250mm overall length are useful reference points when confirming space and bolt alignment.

If the vehicle uses a Denso-type starter, the listed application may be relevant, but the final check should still be made against the actual unit fitted to the vehicle. The starter is described as suitable for start/stop applications, so buyers should only proceed once the specification match is confirmed, especially where there has been a previous replacement or an alternate starter fitted.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is a useful buying consideration, but it does not replace fitment checking. Make sure the pinion diameter of 45mm, pinion at rest of 26mm, and 2.0kW power rating align with the required replacement before fitting.

For workshop or retail customers, the safest approach is to verify the vehicle application, remove the old starter details where possible, and compare the mounting pattern and electrical specification side by side. This starter motor is sold as a new OEX rotating electrical component, so confirming the application first will save time and reduce the risk of returns.

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 DXS4055 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.

OEX Starter Motor 12V 15Th CW Denso Style. Part number DXS4055 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS4055, 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 Q7, AUDI Q7 2007, AUDI Q7 2008, AUDI Q7 2009, PORSCHE CAYENNE, PORSCHE CAYENNE 2009. 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 fitment using part number DXS4055, the 12V 15-tooth CW specification, and the mounting measurements before purchase. Vehicle applications should always be checked against the actual starter fitted to the vehicle, especially where a Denso-style unit or start/stop application is involved.
