Application and Buying Notes

This alternator is listed against a range of Audi and Volkswagen applications, including Audi A6, Audi A6 Allroad, Audi A8, Audi Q7, and Volkswagen Touareg variants. The safest way to check suitability is to compare the vehicle application with the alternator part number 439527, then confirm the mounting style, pulley layout, and electrical connection details against the existing unit.

The 180A charge rating and 12V system voltage need to match the vehicle’s charging system requirements. If the replacement unit does not match voltage, output, pulley section, or rotation, it may not install correctly or may not suit the vehicle setup. The 6 groove pulley, clockwise rotation, and internal regulator are important checkpoints, not optional details.

Mounting dimensions should be checked carefully before ordering. This unit uses a four-point mounting arrangement with a quad leg mount, 127mm mount centre-to-centre, and M8x1.25 / 8 adjusting and pivot hole diameters. Those measurements are useful when comparing the old alternator or the vehicle mounting points.

The connector detail also needs attention. This unit is listed with no connector for revolution counter, so it is sensible to confirm the vehicle’s original plug arrangement before purchase. A close visual comparison of the old alternator, along with the part number 439527, is still the best practical check when the vehicle has multiple possible charging system variants.

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 439527 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 439527, 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 A6, AUDI A6 2004, AUDI A6 2005, AUDI A6 2006, VOLKSWAGEN TOUAREG, VOLKSWAGEN TOUAREG 2004. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by matching part number 439527 and the listed application details, including 12V, 180A, 6 groove pulley, clockwise rotation, internal regulator, and the stated mounting measurements before ordering.
