Ask Us For Help in Decatur When Your BMW Air Filter Is Dirty
Your BMW engine consists of a combustion chamber which combines gasoline and air in order to generate power. This air enters the engine via an air filter, which filters out dirt, bugs, road debris, and other contaminants which might harm the engine.
In order for your engine to function properly, your air filter needs to allow sufficient air to access the engine, and this might be impossible if your air filter becomes clogged and dirty. You will need to let a professional fix this issue because inadequate air can have an adverse effect on the overall efficiency of your BMW.
How Can You Identify A Dirty Air Filter?
Here are a few signs that you may experience in your BMW that might be an indication that your air filter needs to be replaced:
- Constant Decrease in Fuel Economy: If you notice that your gas mileage is dropping, it can be because your engine is trying to compensate for the low amount of air circulation by utilizing more fuel in order to produce enough power. Your air filter will have to be replaced.
- Engine Misfire: Unburnt fuel exits the engine as soot residue due to a limited air supply caused by a very dirty air filter. This soot builds up on your spark plugs, preventing them from delivering the required spark to burn up the mixture of air and fuel. As a result of this, your engine will not start easily; it will misfire and may even begin to jerk
- Strange Engine Noises: You may begin to experience strange sounds coming out from your car anytime it is turned on. You should feel the smooth rotation of the engine in the form of gentle vibrations, so if you notice your car is vibrating inordinately or making popping noises or coughing sounds, it is most likely due to a blocked air filter that is harming your spark plug.
- Your Engine Check Light illuminates: Several modern car engines consume approximately ten thousand [10,000] gallons of air per each gallon of fuel consumed during the combustion cycle. When there is inadequate air supply, carbon deposits can accumulate in the engine, triggering your Check Engine Light. When this occurs, you will need a professional to help you check your air filter as well as other issues. Your Check Engine Light can come on for a number of reasons, so a professional needs to search your onboard computer for any stored trouble code that can help them determine the underlying cause of the light.
- Your Air Filter Looks Dirty: When your air filter is clean, it will appear to be a white or offwhite color, so when you start noticing your air filter changing from this to a much darker color over time, it is an indication that your air filter is becoming dirty and will need attention. However, there is debris and dust that may not become visible even when in bright light. This can accumulate in the inner layer in your air filter, and this will have to be checked whenever you bring your car for maintenance.
- Reduced Horsepower: When you begin to notice that your car doesn’t really respond appropriately or you begin to notice wanking or jerking movements whenever you push your accelerator, it could mean that the engine is not getting enough air to function properly. Replacing the air filter of your BMW can improve horsepower or acceleration by close to 11% because it enhances airflow.
