Product Number: 31231N
The WAI 31231N is a brand-new 12V 2.0kW PMGR starter motor. It is manufactured to Bosch specification, replacing Bosch original-equipment references 0 001 125 021, 0 001 125 022, 0 001 125 051, and 0 001 125 052. It is designed for Skoda and Volkswagen applications running the 1.9 SDI and 1.4 TDI diesel engines — covering Skoda Fabia variants and Volkswagen Polo and Fox models across seven confirmed applications in total.
As a Permanent Magnet Gear Reduction (PMGR) design, the WAI 31231N delivers reliable cranking performance through a compact, efficient motor architecture. The counter-clockwise (CCW) rotation and 10-tooth drive pinion match the original Bosch fitment, ensuring correct engagement with the ring gear without modification. Being brand new, it carries no remanufactured core charge.
The Lester reference for this unit is 31231, which can be used to cross-reference compatibility across aftermarket catalogues.
