WOF tips
Air suspension must be fully functional. Rust is a critical problem, so ensure to get it checked before purchasing. Suspension components are common WOF failures and have a large impact on safety of the vehicle. Tyre condition is also crucial and should be checked.
About the Mercedes-Benz S-Class CL 55 AMG
The W220 S-Class boasts advanced technology, including the innovative Airmatic Suspension system that provides exceptional ride quality. However, regular servicing intervals are crucial: for instance, after approximately 150,000km, it’s important to inspect the cooling system components, such as the water pump, thermostat, and radiator hoses, to prevent overheating issues. Common electrical gremlins, particularly in sensor and control unit functionality, can also arise, so ensure comprehensive checks are conducted before any major road trips. Meanwhile, narrowing in on the transmission, pay attention to any harsh shifting—addressing transmission fluid changes and potential component wear can prolong your vehicle's life. Natural progression leads us to service packs like Cooling and Filtration, where quality parts can be sourced for the best performance.
