  • Causes and Symptoms of a Clogged Fuel Tank Screen Filter in Your Mercedes

    Posted on February 26, 2021 by tannerwpuser
    Mercedes Engine Misfire

    The fuel system in your Mercedes-Benz can be easily damaged by debris and filth. It is one of the most critical components of your Mercedes that promotes optimum vehicle operation, and if these particles make it all the way to your engine, it can cause significant damage and performance problems.

    In this article, we will talk about the filter for the fuel tank screen that Mercedes-Benz so thoughtfully built to best avoid contamination of fuel, including signs of clogs that you should be aware of and how to manage the filter properly.

    Why do you need a fuel tank screen filter?

    Your Mercedes is fitted with various fuel filtration components, namely the W123, such that the fuel that enters the engine is completely free of pollutants or other particles that can lead to engine failure or serious performance issues.

    The system also contains a few other filters in addition to the fuel tank screen filter, such as the pre-filter and a standard fuel filter that most vehicles are fitted with by design. The aim of this third filter introduced by the manufacturer is to capture the larger contaminates that could end up clogging down the line of the subsequent filters.

    Common Signs of a Clogged Fuel Tank Screen Filter

    Although the design of this extra fuel tank screen filter has excellent intentions, like other fuel screens and filters, it may become clogged. This is because it is designed to preemptively capture larger particles, as larger particles can clog a screen/filter in a shorter period of time. The symptoms of a clogged fuel tank screen filter are critical to catch. Below are the most prevalent:

    • illumination of check-engine light
    • difficulty when the car starts
    • misfiring in the engine
    • decrease in control
    • a failing fuel pump

    The fuel flow to your engine needed for ignition and combustion will be significantly impeded by a clogged fuel filter. When your fuel filter gets clogged, the flow of fuel substantially decreases and it reduces the volume of fuel that reaches your fuel tank. The fuel flow is absolutely impeded and your car cannot start or move anywhere.

    Diagnosing a Clogged Fuel Tank Screen Filter

    As the symptoms of a clogged fuel filter can suggest a problem with another region of the fuel system, it is important to diagnose the problem as a problem with the fuel filter initially and correctly. You may need to clean or replace the filter entirely to fix the problem.

    Since the fuel filters in the Mercedes models are typically robust and durable components, they are only blocked from time to time. They also need adequate cleaning. However, if the filter is beyond cleaning or has somehow been damaged or corroded, it should be immediately replaced to restore normal engine service.

    Preventative Maintenance

    Since we know that Mercedes has an added filter for the fuel tank panel, it is important to know what you can do to prevent it from clogging or to prevent any of the filters from clogging. Similar symptoms would occur if any of the filters clog. In order to keep your car running at all times, preventive care is necessary, so here are a few things you should consider:

    • Get the support of a specialist in ongoing repairs and maintenance from Mercedes.
    • Have your professional conduct regular fuel system part checks, including filters and fuel pump components.
    • Use the correct type of gasoline that your car needs. You can find this in your owner’s manual.
    • Follow the suggested maintenance plan in your owner’s manual as well.
    • If you find any of the above signs of a clogged fuel screen in your own vehicle, bring it to your expert for examination immediately.
