Application and Buying Notes

The main identifiers for this alternator are Valeo part number 439800, 12V voltage, and 180A charge output. Those details need to line up with the vehicle’s electrical requirement and the original unit, especially where the charging system uses an internal regulator and a 6 groove pulley.

Mounting details matter just as much as the electrical rating. This unit is listed with 59mm inside mounting legs, 90mm mount centres, 8.5mm adjusting hole diameter, 8 / M8 pivot hole diameter, and quad leg four-point mounting. If the existing alternator does not match those measurements, the part may not install correctly even if the brand appears familiar.

The pulley and connector details also need checking. The pulley outside diameter is 57mm, the pulley section is 6 groove, and the unit is listed with no connector for revolution counter. Those points can affect belt alignment and electrical connection compatibility, so it is worth comparing them directly with the removed alternator before fitting.

Where a vehicle appears in the fitment list, treat that as a starting point rather than the final check. Audi A4, A5, A6, A6 Allroad, A7, Q5, and Porsche Macan applications are referenced, but the exact match still depends on the original part number, mounting pattern, and alternator configuration fitted to the vehicle.

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 439800 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.

Valeo Alternator 12V 180A. Part number 439800 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439800, 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 2011, AUDI A4 2012, AUDI A4 2013, PORSCHE MACAN, PORSCHE MACAN 2014. 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: Confirm compatibility using Valeo part number 439800, the 12V 180A rating, the 6 groove pulley, and the listed mounting dimensions before buying. Vehicle fitment should be checked against the original alternator and application details, as matching model names alone is not enough to confirm the correct part.
