Mercedes-Benz C350 burning smell from engine and manifold replacement needed on Mercedes-Benz C350

Some Mercedes-Benz C350 owners report experiencing a burning smell that may indicate several underlying issues requiring manifold replacement. These owners often find that an overheated engine can produce a burning scent originating from the engine compartment. Additionally, some report that problems with the exhaust system, such as overheating rubber exhaust bushes, contribute to the smell. Oil leaks from engine components, like valve covers, can also lead to burning oil odors when oil drips onto the exhaust manifold. Furthermore, cooling system problems, including belts rubbing against oil cooler lines or collapsed engine mounts, have been noted as potential causes. Lastly, heavy brake use can result in overheated rotors and pads, producing a burning smell, along with issues like dragging calipers. It is crucial for owners to consult a qualified mechanic for an accurate diagnosis and necessary repairs if they detect these symptoms.
