Product matching notes

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

How do I confirm CF-23251N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around BMW - China X1, BMW - Europe 1 (E81) Eng.N43 B16 A, N45 B16 A 116 i 85kw, BMW - Europe 1 (E81) Eng.N43 B20 A, N46 B20 B, N46 B20 C 120 i 115kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 110A, Rotation: CW, Pulley Class: SC6, then cross-check OE numbers BMW 12 31 7 521 488, 12 31 7 521 489, 12 31 7 532 964, 12 31 7 532 968.

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 23249, 23251. That usually narrows the match quickly.
