Q 1. Does this starter motor replace Bosch 0 001 138 003 or 0 001 138 004?

A. Yes. The WAI 33326N directly replaces four Bosch original-equipment references: 0 001 138 003, 0 001 138 004, 0 001 138 047 and 0 001 138 048. If your existing unit carries any of these numbers, this is the confirmed like-for-like replacement. Search our catalogue by OEM number to verify, or ask Simon if you need further confirmation.

Q 2. Which Mini models does this starter motor fit?

A. The WAI 33326N covers 20 Mini applications including the Mini Cooper S (2006–2014), Mini Cooper (2006–2014), Mini Clubman Cooper S (2007–2014), Mini Clubman One (2009–2010), Mini Clubvan Cooper (2012–2014) and Mini Countryman Cooper S (2010–2014). Use the selection widget to match your exact model and engine variant, or search by OEM number. Every fitment shown is backed by our Fit Guarantee.

Q 3. What are the key specifications of the WAI 33326N?

A. It is a brand-new 12V, 1.7kW PMGR (Permanent Magnet Gear Reduction) starter motor with clockwise rotation and an 11-tooth pinion. The Bosch manufacturer reference and Lester number 33326 confirm its position in the Bosch starter range. All figures are shown in the specification table on this listing.

Q 4. What does PMGR mean and why does it matter?

A. PMGR stands for Permanent Magnet Gear Reduction. This design uses permanent magnets in place of wound field coils, combined with a gear reduction stage, to deliver efficient and reliable cranking from a compact unit — characteristics of later Bosch starter architecture. The WAI 33326N replicates these design parameters to OE specification.

Q 5. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.

Q 6. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.
