Q 1. What does the WAI 23175N replace, and which vehicles does it fit?

It covers 47 vehicle applications across Nissan (20 applications), Renault (24 applications), and Dacia (3 applications), including models such as the Nissan Micra (2003–2010), Nissan Kubistar (2003–2016), Renault Clio I (2001–2003), Renault Kangoo (2001–2016), Renault Megane (2003–2016), Dacia Logan (2005–2016), and Dacia Sandero (2008–2016). Use the selection widget to confirm fitment to your exact make, model, and engine — every match is backed by our Fit Guarantee.

Q 2. Does this alternator replace VALEO part number SG12B103?

A. Yes. The WAI 23175N cross-references directly to VALEO SG12B103. That is the sole OE reference published for this part. If you are working from a different reference number, search our cross-referenced catalogue by OEM number or ask Simon to confirm the match.

Q 3. Will this fit a Nissan Micra?

A. The Nissan Micra (2003–2010) is included in the confirmed fitment list for the WAI 23175N, which covers 20 Nissan applications in total. To verify the fit against your specific engine variant and year, use the vehicle selection widget or search by your OEM part number. Fitment is backed by our Fit Guarantee.

Q 4. Is this a brand-new alternator or a remanufactured exchange unit?

A. The WAI 23175N is supplied brand new. It is not a remanufactured or reconditioned exchange part, so no core return is required.

Q 5. What is the Lester number for this alternator?

A. The Lester number for the WAI 23175N is 23175. This is a standard cross-reference identifier used by automotive electricians and trade suppliers to verify rotating electrical components across brands.

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. 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.
