Lot B7546: 2007 Mercedes-Benz CL600

The 2007 CL600 ABC (Active Body Control) system has several well-documented issues you should know about:

Most Common Problems:

1. Pump failures - You will hear whining noises around 2000 RPM, and the pump may lose pressure (should stay above 100 PSI)
2. Valve block issues - Solenoid valves can fail, causing erratic suspension behavior and repeated hose failures
3. Accumulator failures - These cause soft suspension and brief ABC Visit Workshop messages when hitting bumps
4. Pulsation damper problems - Can create humming noises and system vibration issues
5. Fluid leaks - Various seals and hoses develop leaks over time

Red Flags to Watch For:

• Whining or humming from the suspension
• Car sitting lower after being parked overnight
• ABC warning messages on the dash
• Uneven ride height between corners
• Hard or bouncy ride quality

The Good News: Most components (except the pump) are relatively accessible for replacement, and the system is well-understood by Mercedes specialists. Regular fluid changes every 30,000-50,000 miles can prevent many issues.

At 61,320 miles, this CL600 is right in the range where some of these issues might start appearing, so definitely have a Mercedes specialist inspect the ABC system before purchasing. The ABC system provides incredible ride quality when working properly, but repairs can be expensive if multiple components fail.

Would you like me to help you find similar CL600s with fewer miles, or do you have questions about what an ABC system inspection should include?
