Product Number: 11745N
The WAI 11745N is a brand-new 12V 175A alternator. It is designed as a direct replacement for BOSCH original-equipment units, carrying OE references BOSCH 0 125 711 068 and BOSCH 0 125 711 087. Fitted to Mercedes and Mercedes-Benz models including the GLA45 AMG and CLA45 AMG, it covers three applications in total and is built to BOSCH IR/IF (internal regulator / internal fan) specification, making it a plug-in substitute for the original unit without additional wiring or modification.
The WAI 11745N is engineered to match OE output and electrical characteristics precisely. Running at a clockwise rotation with an SC5 single-claw pulley, it delivers the same 175-amp charging capacity as the original BOSCH fitment. IR/IF design means both the voltage regulator and cooling fan are housed internally, keeping the installation clean and reducing external component count. Being brand new rather than remanufactured, there is no core charge and no exchange requirement.
Application coverage spans Mercedes and Mercedes-Benz petrol models in the AMG performance range, with confirmed fitment on the GLA45 AMG (2014–2019) and CLA45 AMG (2014–2019). Always verify your engine variant and build date against the full fitment list before ordering.

A. The WAI 11745N is a direct replacement for BOSCH OE references 0 125 711 068 and 0 125 711 087 — both numbers confirmed in the cross-reference data for this part. If you are working from the OE number stamped on your original unit, either of those references confirms this is the correct replacement. Use our cross-referenced catalogue or ask Simon to verify fitment if you have a different reference on your unit.
A. The WAI 11745N covers three Mercedes and Mercedes-Benz applications, including the Mercedes GLA45 AMG (2014–2016), Mercedes-Benz CLA45 AMG (2014–2019), and Mercedes-Benz GLA45 AMG (2015–2019). Use the selection widget or search our catalogue by model and engine to confirm your exact build-date variant is covered. Every fitment shown is backed by our Fit Guarantee.
A. IR/IF stands for Internal Regulator / Internal Fan. It means the voltage regulator and the cooling fan are both built inside the alternator casing rather than mounted externally. For fitting, this means no separate external regulator needs to be wired in — the WAI 11745N connects directly in place of the original BOSCH unit, making it a straightforward like-for-like swap on the supported Mercedes and Mercedes-Benz applications.
A. The WAI 11745N is fitted with an SC5 single-claw pulley, matching the original BOSCH specification. Confirm that your existing drive belt and pulley arrangement corresponds to the SC5 profile before installation. If you are unsure, ask Simon or contact our team with your vehicle details.
A. The WAI 11745N is brand new. There is no core exchange requirement and no surcharge for returning a worn unit — the part is supplied ready to fit straight from the box.
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.
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.
