Buying a car, especially a sophisticated machine like a 2001 S500 Mercedes Benz, is an exciting experience. However, to ensure lasting enjoyment and reliability, a thorough post-purchase inspection is crucial. As a car detailing and auto repair expert at cardetailinguk.com, I understand the nuances of vehicle maintenance, and for a car like the W220 S-Class, proactive care is key. Let’s delve into the essential checks and maintenance steps you should undertake after acquiring your 2001 S500.
Initial Mechanical and Safety Checks
The first step is to identify any potential issues that could leave you stranded. For your 2001 S500 Mercedes Benz, this involves a comprehensive check of critical systems:
- Drive Belts: Inspect for wear, cracks, or fraying. A broken belt can lead to serious problems, including loss of power steering and overheating.
- Coolant Leaks: Look for any signs of leakage around hoses, the radiator, and the water pump. Mercedes engines are sensitive to overheating, so maintaining a healthy cooling system is vital.
- Oil Leaks: Check for leaks around the valve cover gaskets, oil pan, and other engine seals. Address any leaks promptly to prevent engine damage and maintain optimal oil levels.
- Brake System: Thoroughly inspect the brakes, including pads, rotors, and brake lines. Pay close attention to brake fluid leaks and the overall condition of the system. Braking performance is paramount for safety.
- Interior Water Leaks: Examine the interior for any dampness or signs of water intrusion, especially in the footwells and trunk. Water leaks can lead to mold and electrical issues, as one owner experienced with an S600.
- Wheels and Tires: Check for wheel wobble, tire wear, and any signs of damage. Ensure tires are properly inflated and have adequate tread depth for safe driving.
- Suspension System: Inspect for any signs of damage or wear in the suspension components. Listen for unusual noises like clunks or squeaks when driving over bumps.
- Transmission: Assess the transmission’s performance. Note any rough shifting or unusual noises. Smooth gear changes are a hallmark of a well-maintained Mercedes transmission.
- Engine Misfires: Be alert for any engine misfires, indicated by rough idling or hesitation during acceleration. Misfires can point to issues with spark plugs, ignition coils, or fuel delivery.

Road Testing and Reliability Assessment
Once the initial checks are complete and any immediate issues are addressed, it’s time to assess the real-world reliability of your 2001 S500 Mercedes Benz through a series of test drives.
- Local Driving: Start with daily local driving for a couple of weeks. This allows you to identify any minor issues that may not be apparent during a short inspection.
- Extended Freeway Test: Progress to longer drives, including a “road trip readiness” test. A two-hour round trip on the freeway is a good benchmark to gauge the car’s performance and identify any potential problems at higher speeds and longer durations.
Addressing the ABC Suspension System
A critical aspect specific to your 2001 S500 Mercedes Benz is the Active Body Control (ABC) suspension system. This advanced system provides exceptional ride quality and handling, but it requires proper maintenance.
- ABC System Inspection: Pay particular attention to the ABC system. Listen for any unusual noises from the pump or struts. Check for leaks in the hydraulic lines and around the valve blocks.
- Fluid Flush and Rodeo: It is highly recommended to have the ABC fluid thoroughly flushed and replaced. Consider performing an ABC “rodeo” test, which cycles the suspension through its full range of motion to help identify any issues and ensure proper system function.
- Accumulator Replacement: ABC accumulators are known to fail over time. Replacing them proactively can prevent sudden suspension failures, like the rear accumulator issue mentioned earlier, which can cause the car to drop to the ground.
