Yes — this 2005 Mercedes-Benz SL-Class SL500 (R230) manual does cover the ABC suspension system, which includes information on the accumulators and related components.
For the Active Body Control (ABC) system (the hydraulic self-levelling suspension used on the R230 SL500), the manual includes:
- System overview and description of how ABC works
- Component locations (pump, valves, sensors, accumulators)
- Removal/installation procedures for ABC parts
- Service and troubleshooting procedures related to hydraulic components, pressure, leaks, etc.
That means if you’re looking for information on replacing the ABC suspension accumulators — front and rear — the manual does cover the system and how those components fit into it.
