Application and Buying Notes

Before ordering, check that your vehicle requires Valeo part no. 439798 and that the charging system is a 12V setup with a 180A alternator. The listed mounting details matter as much as the electrical rating, so confirm the direct mount, direct fastening arrangement, 56mm mount centre to centre, and 70mm mount leg thickness against the unit currently fitted.

The pulley configuration also needs to match. This alternator is specified with a 6 groove pulley and a 57mm pulley outside diameter, so the belt alignment and groove count should be checked carefully before purchase. The connector note is also important: it is listed as no connector for revolution counter, which means the plug arrangement should be matched to the vehicle application and the removed unit.

Fitment references are provided for Audi A4, Audi A5, Audi Q5, and Porsche Macan, but model naming alone is not enough to confirm suitability. Always compare the part number, mounting points, pulley section, and connector details with the existing alternator or the vehicle application data used by your workshop or parts lookup.

This is a new Valeo alternator with a one year warranty, supplied as each. If you are replacing a worn unit, the safest approach is to verify the physical dimensions, regulator type, and electrical output before fitting, particularly where the vehicle has had prior repairs or an alternator change that may not match the original specification.

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 439798 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.
