Q 1. Does this starter motor replace BOSCH 0 001 125 018?

A. Yes. The WAI 17820N directly replaces BOSCH original-equipment numbers 0 001 125 018, 0 001 125 019, 0 001 125 048 and 0 001 125 049 — all four BOSCH references are confirmed cross-references for this part. Use the OE number to search our cross-referenced catalogue, or ask Simon if you need to verify your specific unit.

Q 2. Does it also replace any VALEO starter motor numbers?

A. Yes — the WAI 17820N is also cross-referenced to VALEO D7RS150 and VALEO D7RS50. If your vehicle currently carries either of those VALEO part numbers, the 17820N is the confirmed replacement. Search our catalogue by OE number or ask Simon to confirm fitment for your vehicle.

Q 3. Which vehicles does the WAI 17820N fit?

A. This starter motor fits Volkswagen (51 applications), Seat (17), Ford (9), Audi (6) and Skoda (3) — 86 applications in total. Confirmed examples include the Ford Galaxy (WGR) 1.9 TDI 66 kW, 85 kW and 96 kW (1995–2006), the Audi S3 (1999–2003) and Audi TT / TT Roadster 1.8 T quattro models (1999–2005). Use the selection widget to match your exact make, model and engine variant, or search by OE number. Every fitment shown is backed by our Fit Guarantee.

Q 4. What engine variants of the Ford Galaxy does this starter cover?

A. The 17820N covers the Ford Galaxy (WGR) with 1.9 TDI engines coded 1Z, AHU and ANU (66 kW, 1995–2006), engine code ASZ (96 kW, 2003–2006) and engine code AUY (85 kW, 2000–2006). Use the selection widget with your engine code to confirm your exact variant, or ask Simon.

Q 5. What does PMGR mean, and why does it matter when choosing a starter?

A. PMGR stands for Permanent Magnet Gear Reduction. Rather than using wound field coils, the motor uses permanent magnets, and an integral gear-reduction stage multiplies the torque output. The result is a compact, lightweight unit that delivers strong, consistent cranking. You must match the PMGR design type to your original starter — fitting a conventional or PMGR unit interchangeably is not always possible, so verify this against your existing part or OE reference.

Q 6. What are the key electrical and mechanical specifications of this starter motor?

A. The WAI 17820N runs on 12V, produces 2.0 kW of output power, rotates counter-clockwise (CCW) and uses a 10-tooth drive pinion. The design is PMGR (Permanent Magnet Gear Reduction) and the Lester reference number is 17820. The unit is supplied brand new — not remanufactured.

Q 7. Is this a new starter motor or a remanufactured exchange unit?

A. It is a brand-new starter motor. There are no worn or reconditioned internal components, and there is no core-charge or exchange requirement — you simply fit and retain the old unit if you wish.

Q 8. 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 9. 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.
