Common Problems and Solutions for the W124

While the W124 is known for its durability, it's not immune to issues. Some common problems include electrical gremlins, rust, and issues with the automatic transmission. For example, electrical problems can range from faulty wiring to malfunctioning sensors, and can manifest as anything from non-functional lights to erratic engine behavior. Rust is another common enemy of the W124, particularly in areas exposed to the elements. Regular inspections and preventative measures, such as rustproofing treatments, are crucial to prevent rust from taking hold. The automatic transmissions in some W124 models are also prone to issues, such as rough shifting or leaks. Regular fluid changes and proper maintenance can help extend the life of the transmission. If you find yourself facing electrical issues, a thorough diagnosis is essential. Start by checking the fuses and relays, and then move on to inspecting the wiring and connectors. For rust, address any areas of concern as soon as possible, and consider applying a rust inhibitor. For transmission issues, make sure to change the transmission fluid according to the manufacturer's recommendations. For electrical issues, always disconnect the battery before working on the electrical system to avoid shocks. For rust problems, it is crucial to perform regular inspections, particularly in areas like the wheel wells, undercarriage, and rocker panels. For transmission problems, ensure that you always use the correct type of transmission fluid. In addition to these issues, it is important to stay on top of regular maintenance to prevent problems from arising in the first place. That means changing the oil and filter regularly, replacing the spark plugs, and checking the fluids. Keeping up with these maintenance tasks will go a long way in ensuring your W124 remains reliable for years to come.
