Genuine Mercedes 221-320-02-14 Active Body Control Suspension Fluid Reservoir

The Genuine Mercedes 221-320-02-14 is a factory OEM Active Body Control (ABC) suspension fluid reservoir designed for select Mercedes-Benz S-Class and CL-Class models. This critical component stores hydraulic fluid for the ABC system, which uses computer-controlled hydraulics to actively manage body roll, pitch, and dive during various driving conditions.

Key Features:

• Genuine Mercedes-Benz OEM part ensures perfect fit and factory specifications
• Integral component of the Active Body Control hydraulic suspension system
• Stores ABC hydraulic fluid (Pentosin CHF11S specification) when not in use
• Features integrated dipstick for checking fluid levels at different vehicle positions
• Includes mounting provisions for ABC filter assembly on reservoir cap
• Pressurized design works with the ABC pump to maintain system pressure

The ABC reservoir is essential for proper suspension operation, working in conjunction with the hydraulic pump, valve blocks, and suspension struts. Regular monitoring of fluid levels in this reservoir is critical for system health, as low levels can indicate leaks or lead to system failure. This genuine Mercedes part is manufactured to exact OEM specifications and backed by factory warranty for reliable, long-term performance.

Technical Note: The ABC fluid reservoir is separate from the power steering reservoir. Fluid levels should be checked with the vehicle on level ground, trunk empty, and fuel tank full. Measurements should be taken 10 minutes after engine shutdown to allow fluid to drain from accumulators.
