Valeo Alternator 12V 140A 439725

The Valeo Alternator 12V 140A, part number 439725, is a rotating electrical component supplied as each and identified for direct fastening applications. It is rated at 140 amps and carries a one year warranty, making the key checks before purchase the part number, mounting style, and electrical output requirement.

This alternator is listed as a Valeo unit with no connector for revolution counter, so the connector arrangement matters just as much as the physical fit. At 7.69 kg, it is a substantial component, and the correct installation depends on matching the vehicle application and the fastening type rather than relying on appearance alone.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles. That matters for buyers comparing replacement alternators because the important points are the 12V system voltage, 140A charge current, direct fastening setup, and the specific part number 439725 rather than generic alternator shape or pulley location.

If you are replacing an existing alternator, confirm the vehicle uses a 12V charging system and that the replacement requirement matches 140A output. For euro vehicle applications, the safest approach is to compare the current unit’s identification and mounting details before ordering.

Application and Buying Notes

Before ordering, confirm the replacement alternator matches part number 439725 and the vehicle is set up for a 12V charging system with 140A output. The supplied fitment data points to Audi TT applications from 2008 to 2018 and Volkswagen Passat applications from 2010 to 2014, but you should still compare the existing unit and vehicle details carefully before buying.

The fastening type is direct fastening, so the mounting arrangement needs to line up with the vehicle’s original setup. Alternators can look similar across different models and output ratings, but the wrong mounting style or connector arrangement can prevent installation or leave the charging system incompatible.

The connector / clamp detail is listed as no connector for revolution counter, which is a useful checkpoint when matching the replacement unit. If the existing alternator uses a different connector arrangement, or if the vehicle’s charging system is not specified for this configuration, the correct choice should be verified before purchase.

Weight is listed at 7.69 kg, which gives a general sense of the unit’s size and handling but should not be used as the only fitment guide. The most reliable checks are the part number, voltage, amperage, fastening type, and any application details already confirmed for the vehicle.

This alternator is a Valeo rotating electrical component and is supplied with a one year warranty. Warranty coverage does not replace fitment verification, so it remains important to confirm the original alternator details, especially where the vehicle has had prior electrical repairs or non-standard replacement parts fitted.

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 439725 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.
