Application and Buying Notes

Before ordering, compare the part number VXA933 with the number on the original alternator and check the listed Valeo style specification. The mounting details are specific: twin leg mount, 60mm inside mounting legs, 8 / M8 pivot hole diameter, 9mm adjusting hole diameter, and 148mm mount centre to centre.

The pulley setup is also important for compatibility. This unit uses a 6 groove pulley with a 50mm outside diameter, so it needs to match the belt arrangement already on the vehicle. The alternator is 12V and rated at 90A, with an internal regulator and a "W" terminal.

Fitment data includes a wide range of vehicles across Audi, BMW, Citroën, Mercedes-Benz, Peugeot, Porsche, Renault, Seat, Volkswagen and Volvo applications. That said, alternators can vary within the same model range, so the safest approach is to confirm the original unit type, mount style, pulley section and terminal arrangement against the vehicle already fitted.

If the original alternator differs in mount spacing, pulley groove count, terminal layout or regulator type, do not rely on the model name alone. Matching the physical dimensions and part number is the practical way to avoid installation issues and unnecessary returns.

The unit is supplied new and weighs 6.06kg. For workshop planning, that weight and the mounting style are useful indicators when comparing it with the part being removed and when checking that the brackets, belt alignment and electrical connection points are all consistent.

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 VXA933 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.
