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 BOSCH and replacement references including 21253 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Share target quantity, destination, sample need, and packaging requirement so Crankvia can confirm the practical supply path.

Product matching notes

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

How do I confirm CF-21253N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Audi - Europe A4, Audi - Europe A6, Audi - Europe Cabriolet and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 70A, Rotation: CW, Pulley Class: S5, then cross-check OE numbers Audi, Volkswagen 058 903 018, 058 903 018X, 058-903-016.

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 21253. That usually narrows the match quickly.
