Application and Buying Notes

Before ordering, match the part number 439733 and confirm the alternator layout on the vehicle. This unit is a 12V, 110A Valeo alternator with an internal regulator and a 6 groove pulley, so the electrical and belt drive setup must line up with the vehicle already fitted.

The mounting details matter here. This alternator has a quad leg mount, 127mm mount centre to centre, 61mm inside mounting legs, and an 8.5 / M8 pivot hole diameter. If any of those dimensions differ from the original unit, it is not the right match.

The connector detail also needs checking. This unit is listed with no connector for revolution counter, which makes the plug arrangement and instrument or charging system requirements worth confirming against the existing alternator before purchase.

The listed fitment references point to selected Audi, Skoda and Volkswagen applications, but they are not a substitute for checking the exact vehicle and engine setup. When comparing replacements, use the original part number, pulley groove count, mount style and connector type together rather than relying on vehicle badge alone.

If you are replacing a failed alternator, inspect the belt condition, pulley alignment and mounting points at the same time. A correct 12V, 110A replacement still needs the vehicle’s physical mounting and electrical configuration to match for a proper installation.

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 439733 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.
