What Problems Does the 1983 Mercedes-Benz 300 Have?
The 1983 Mercedes-Benz 300, part of the W123 generation, is generally lauded for its exceptional long-term reliability. However, certain issues can arise with age and mileage. One of the most common concerns is rust, particularly in areas prone to moisture like the wheel arches, rocker panels, door bottoms, and the rear parcel shelf. Early inspection for rust is crucial.
Engine-related issues, while infrequent for the robust OM617 diesel, can include worn injector pumps, leaky fuel lines, and glow plug failures. The automatic transmission, while generally durable, can develop leaks or shifting problems if not properly maintained. The vacuum system, which controls central locking and other functions, can become brittle and leak, leading to malfunctions.
Rubber components, such as suspension bushings, engine mounts, and various hoses and seals, are subject to degradation over time, leading to squeaks, leaks, and potential failures. Air conditioning systems can lose their charge or develop compressor issues. Electrical gremlins, though not rampant, can occur with age, affecting things like the power windows or dashboard lights.
There were no major widespread recalls that significantly impacted the reputation of this model year. The long-term reliability is largely dependent on meticulous maintenance. Owners who consistently followed the recommended service intervals and addressed minor issues promptly have seen these cars exceed 300,000 and even 400,000 miles.
