The 2004 model year

Overview

For 2004, the U.S. W220 range continued with rear- and all-wheel-drive S 430 and S 500 sedans plus the rear-wheel-drive S 55 AMG and S 600. Mercedes-Benz's retrospective records the seven-speed automatic as a 2004 technology change on S 430 and S 500 models without 4MATIC; the 4MATIC and flagship transmission boundaries remain distinct.

Year over year

What changed

  • Rear-wheel-drive S 430 and S 500 models adopted the seven-speed automatic.
  • The six-configuration V8, AMG, and V12 structure otherwise carried over.

Worth knowing

Notable

  • A shared badge does not imply a shared transmission: rear-drive and 4MATIC V8 cars are separate fitment applications.

Living with it

Reliability & ownership notes

  • Inspect the individual car's Airmatic or optional Active Body Control system, electronics, corrosion condition, and documented service history; generation reputation is not proof of a fault on every car.
  • Match filters, ignition parts, fluids, transmission service parts, and suspension components to the exact engine, drivetrain, chassis number, and build date before ordering.

Maintenance & service parts

Keep your 2004 S-Class on the road

Start with the service interval, then match the engine or exact version you own. Order links appear only when a catalog-backed part number is available, and every listing still needs a fitment check.
