Common Issues with the Mercedes Benz CLK350 Air Filter
Your Mercedes Benz CLK350 is one stylish vehicle that's been built for maximum comfort and convenience. Nice to look at and easy to drive, you wouldn't ask for more when it comes to this ride. But all that class and features won't mean much if you've got problems with its air filter. Once this filter goes bad, then expect to experience rough engine noises, lower fuel mileage, and higher emissions from your vehicle. Learn to identify symptoms of a bad Mercedes Benz CLK350 air filter so you could replace it at once, before it affects your car's performance in the long run.
Lower fuel efficiency is a sign that you might have a clogged air filter, which in turn is affecting how your engine burns up fuel. Your vehicle's engine relies on a proper fuel to air ratio to effectively burn fuel and power up your car. If you have a clogged air filter, then your engine might not be receiving enough air to properly combust fuel. Depending on the air filter that you have installed, you can either wash it if you have a metal filter or simply replace it if it's made from paper or some other disposable material.
Black smoke exhaust
Again, another symptom of a bad air filter is black smoke from your exhaust. If the air filter is clogged, your engine will use more fuel to run, which in turn can lead to a "rich" mixture that leads to a blacker exhaust.
Rough noise coming from the engine
Because of the lack of air coming in through a dirty filter, even your engine's spark plugs could get affected. A broken air filter might allow dirt and debris to enter, which in turn can clog your spark plugs. Replacing the air filter and cleaning or even replacing your spark plugs should solve the problem.
Most mechanics would advise drivers to simply replace their air filter, whether they're dirty or not, every 12,000 to 15,000 miles to ensure that they don't break or clog up. It's pretty simple to replace an air filter on your own and the added pre-emptive care will make sure that your Mercedes Benz CLK350 will run smoothly for a longer time.
