Valeo Alternator 12V 180A Part No. 439799

This Valeo alternator is a new 12V unit with a 180A power rating and alternator charge current of 180A. It is identified by part no. 439799 and uses an internal regulator, making it a straightforward rotating electrical replacement where the application matches.

It has a 6 groove pulley, clockwise rotation, and a quad leg alternator mount with four-point mounting. The listed mount hole diameter is 9 / M8, with 126mm centre to centre mounting and 61mm inside mounting legs, so those dimensions are useful when comparing against the original unit.

Valeo is noted here as a leading OE manufacturer and supplier for many euro vehicles. The alternator is supplied new, weighs 7.53kg, and includes a one year warranty.

The unit is described with pin code IR228 and no connector for revolution counter. If you are matching an alternator for a European application, the physical layout and part number are the safest checkpoints before ordering.

Application and Buying Notes

The most important checks on this Valeo alternator are part no. 439799, 12V system voltage, 180A output, and the mounting arrangement. The unit uses a 6 groove pulley, clockwise rotation, four-point mounting, a quad leg mount, and 126mm centre to centre mounting, so those details need to line up with the removed alternator.

This alternator is listed with an internal regulator and no connector for revolution counter. That matters when comparing plug style and vehicle wiring, because the wrong connector style or regulator arrangement can stop the unit from matching correctly even if the housing looks similar.

The physical dimensions are also relevant: the mount hole diameter is 9 / M8, inside mounting legs are 61mm, and pulley outside diameter is 49mm. Those measurements are the best way to compare the replacement against the original unit in hand.

Although Audi applications are referenced in the fitment data, do not rely on vehicle model name alone. Alternator fit can vary by engine, build date, charging system, and previous repairs, so the original part number and mount details should be checked carefully.

Valeo is noted as an OE supplier for many euro vehicles, and this unit is supplied new with a one year warranty. Even so, the safest purchase decision is to confirm the application details, mounting style, pulley setup, and electrical connection before fitting.

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 439799 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 439799, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A4, AUDI A4 2007, AUDI A4 2008, AUDI A4 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.

Compatibility note: Please confirm fitment using part number 439799, the listed 12V 180A specification, and the alternator’s mounting and connector details against the original unit before ordering.
