Quality and test focus

Core specifications such as voltage, power or amperage, rotation, teeth, and design are reviewed before sample or bulk quotation.

Replacement sourcing support

MFR VALEO and replacement references including 11938, 21073 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-21073N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Audi A3 Quattro, Audi A3, Audi Q3 and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 150A, Rotation: CW, Pulley Class: SC6, then cross-check OE numbers Audi, Volkswagen 06K-903-023-B, 06K-903-023-BX, 06K-903-023-G.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 11938, 21073. That usually narrows the match quickly.
