Choosing alternators for your Mercedes-Benz S-Class W221
This page covers the Mercedes-Benz S-Class W221 generation (2005–2013). Specifications can vary by engine, year, trim and equipment, so the generation alone does not confirm compatibility.
What to check before ordering
Check the original part number, amperage rating, pulley design and electrical connector. Engine and equipment variants can differ.
Where possible, compare the details and photographs with the part fitted to your vehicle. If you need help identifying a suitable replacement, contact Smart Torque support with your registration and any part number you have.
