Catalytic converters have no moving parts, so they rarely fail. But catalytic converter failure is a possibility – whether due to engine misfires, coolant leaks, leaky fuel injectors, burned engine oil, bad oxygen sensor, or physical damage, to name some of the major culprits.
A failing catalytic converter can negatively impact your Mercedes in a variety of ways: performance will suffer, you may notice unusual odors, including the rotten eggs smell, rattling noises, and the check engine light will be illuminated. We highly recommend contacting MB Clinic in Denver to inspect and diagnose the cause of these symptoms as soon as possible. Continued driving with a failed catalytic converter can cause serious engine damage, and in some, fortunately very rare cases, can result in a vehicle fire.
Catalytic converters reduce harmful emissions by converting engine exhaust gases (carbon monoxide, hydrocarbons, and nitrogen oxides) into carbon dioxide, nitrogen, oxygen and water vapor. Over time, catalytic converter may become clogged, contaminated or damaged - resulting in loss of function, and potential damage to the engine.
So if you notice following symptoms:
- rattling noise coming from underneath your Mercedes
- rotten eggs smell
- sluggish performance
- check engine light
call MB Clinic and let our factory trained technicians diagnose the root cause of the issue.
