Genuine Alternator 12V 110A Valeo 04E903015GX

This Genuine Products alternator is a 12V, 110A unit built for Valeo applications and identified by part number 04E903015GX. It is supplied as a new alternator, not remanufactured, and uses an internal regulator with CW rotation.

The mounting and pulley details are important for correct replacement. This unit has a quad leg alternator mount, 128mm centre-to-centre mount spacing, 61mm inside mounting legs, an M8x1.25 / 8.5 pivot hole diameter, and a 52.5mm pulley outside diameter with a 6 groove belt section.

For buyers replacing a failed charging unit, the key checks are the part number, the electrical rating, and the physical mounting dimensions. This alternator is rated at 110 amps at 12 volts and weighs 6.24kg, so it is a substantial rotating electrical component that should be matched carefully before ordering.

Application and Buying Notes

The safest way to order this alternator is by matching part number 04E903015GX first, then checking the mechanical details against the removed unit. The important points here are the 12V charging system, 110A output, internal regulator, CW rotation, 6 groove pulley, and quad leg mount arrangement.

The physical dimensions matter just as much as the electrical rating. Confirm the 128mm mount centre-to-centre measurement, the 61mm inside mounting legs, the M8x1.25 / 8.5 pivot hole diameter, and the 52.5mm pulley outside diameter before fitting. If any of those differ from the original unit, the alternator may not align correctly or may not suit the belt drive.

This unit is listed as new and carries a one year warranty. That said, alternator replacements should still be matched carefully to the vehicle’s charging system and bracket layout. When replacing a Valeo-style alternator, compare the old unit side by side with this one and verify the connector, mount pattern, pulley groove count, and rotation direction to avoid costly returns.

If you are buying for a Volkswagen Golf application, use the provided model-year guidance only as a starting point. Vehicle build changes can affect alternator fitment even within the same model range, so the part number and mounting measurements remain the most reliable checks 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 04E903015GX 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 04E903015GX, 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 alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include VOLKSWAGEN GOLF, VOLKSWAGEN GOLF 2014, VOLKSWAGEN GOLF 2015, VOLKSWAGEN GOLF 2016. 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 One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number 04E903015GX and the listed application details, including 12V, 110A, Valeo unit make, CW rotation, 6 groove pulley, quad leg mount, and the stated mounting dimensions before ordering.
