Q 1. Which BOSCH part numbers does the WAI 30233N replace?

A. The WAI 30233N directly replaces three BOSCH original-equipment references: 0 001 138 039, 0 001 139 040 and 1138040. These are all the cross-references published for this part. You can also search our cross-referenced catalogue by any of those OEM numbers to confirm fitment.

Q 2. Will this starter motor fit my Mini?

A. Yes — the WAI 30233N covers 18 Mini applications, including the Clubman Cooper S (2011–2013), Clubman Cooper (2010–2015), Clubman One (2010–2015), Cooper S (2011–2015), Cooper (2010–2015), Countryman Cooper S (2011–2015), Countryman Cooper (2010–2015) and Countryman One (2010–2015). 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 does PMGR mean, and why does it matter for my Mini?

A. PMGR stands for Permanent Magnet Gear Reduction. The permanent magnet construction replaces the wound field coils found in older designs, reducing current draw and heat generation. The gear reduction stage allows a smaller, lighter motor to produce sufficient torque for reliable cold-weather cranking. The WAI 30233N is a PMGR unit built to BOSCH specification, so it matches the design intent of the original factory-fitted starter.

Q 4. Is the WAI 30233N brand new or remanufactured?

A. It is brand new. There is no exchange core charge, no worn brushes or commutator to worry about, and no refurbished components — it arrives ready to fit straight from the box.

Q 5. What are the key specifications — voltage, power output and pinion teeth count?

A. The WAI 30233N operates at 12V with a rated output of 1.4kW. It uses an 11-tooth pinion and turns clockwise (CW). The Lester reference number is 30233. Full specifications are shown in the table on this listing.

Q 6. 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 7. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
