Application and Buying Notes

Before ordering, match the part number 439814 and compare the mounting style, pulley details and connector arrangement with the original alternator. This unit is specified as 12V, 140A, CW rotation, internal regulator, quad leg mount and direct fastening, so those details need to align with the vehicle application.

The pulley is 6 groove with a 56mm outside diameter, and the alternator is listed with a 70mm mount leg thickness. Those measurements matter when checking physical fit, belt alignment and bracket compatibility against the removed part.

The connector note is important here: this alternator is listed with no connector for revolution counter. If the original alternator uses a different plug or a different rev counter arrangement, the replacement may not be suitable without confirming the application details first.

Fitment data supplied with this product points to selected AUDI, CUPRA, SKODA and VOLKSWAGEN applications. Even where a model name appears in the fitment listing, engine and charging system variations can still apply, so the safest check is to compare the vehicle details and the existing unit against the listed part number and specifications.

Weight is listed at 7.826kg and the unit is new rather than remanufactured. For workshop planning, that gives a useful guide for handling and confirms the product is not a reman unit. The one year warranty applies to the supplied alternator under normal purchase terms.

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 439814 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 439814, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A1, AUDI A1 2014, AUDI A1 2015, AUDI A1 2016, CUPRA ATECA, CUPRA ATECA 2022. 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.
