All cars and SUVs have both a cabin air filter and an engine air filter. Your Mercedes-Benz is no different. What they do is help prevent the buildup of airborne contaminants, both in your HVAC system and in engine parts, respectively. In short, they help keep your heating, air conditioning, and engine working right.
If your vehicle didn't have either filter, those pollutants would start to cause problems with everything from your air intake, fuel injectors, and spark plugs to the many parts of your heater and air conditioner. Unfortunately, air filters can wear out with age. They can also clog full of dirt and debris. When they do, related problems follow.
Signs Your Car Air Filters Need Replacing
- Your vehicle's emissions increase
- Your fuel efficiency worsens
- Your motor begins to stress and misfire.
- Your heat and AC systems stop working as well
You can keep these things from happening by changing both air filters and doing it consistently.
When Should I Replace the Air Filters in My Mercedes-Benz?
Usually, about every 12,000 to 15,000 miles or so. But it's a good idea to look for the symptoms that suggest it's time. They include:
- A degraded filter
- Accumulated debris
- Unusual engine noises
- Unclean smells in your cabin
- High exhaust production
- A lit Check Engine light on the dash
