Volkswagens are well-known for their smooth performances and excellent fuel economy. However, your Volkswagen’s performance won’t remain smooth for long if it attempts to operate on dirty fuel. That’s where the fuel filter comes in. This engine component sits between the fuel tank and the engine and pulls dirt and debris from the gasoline that flows through it. Overtime, these contaminants may clog the filter, which can cause serious problems for your vehicle’s functioning. Therefore, all Volkswagen owners should know how to identify and fix clogged fuel filters.
Symptoms of a Clogged Fuel Filter
One of the earliest symptoms that may indicate a clogged fuel filter is difficulty when starting your Volkswagen’s engine. When the filter is packed full of debris, the clog makes it difficult for gas to pass through, and because all vehicles need fuel to function, this prevents the engine from starting. In most instances, the fuel will eventually force its way through the filter, allowing the vehicle to start after a few successive attempts. Regardless, if your Volkswagen does not start on the first try, you should have it checked for a clogged filter and other potential engine problems.
Another common symptom of a clogged filter is engine misfires. This is because engine cylinders require adequate fuel to fire, and if a clogged filter prevents gasoline from reaching the engine, the cylinders will be unable to fire on time. Misfires caused by clogged fuel filters are especially common when driving up steep hills or towing heavy loads, as these situations put considerable stress on the engine.
A third potential indicator of fuel filter problems is reduced fuel economy. If a faulty filter prevents gasoline from reaching the engine, the engine will begin pumping faster to compensate. Ultimately, this will cause your Volkswagen to consume more fuel per mile.
Alternatively, the engine might be unable to draw enough oil through the filter to function properly even though it’s operating at an increased speed. If this is the case, you will notice a considerable decline in your vehicle’s engine power. Much like engine misfires, this symptom will be especially noticeable when driving uphill or pulling heavy loads.
If your Volkswagen’s fuel filter is clogged, these conditions may also cause its engine to stall. This will occur when the engine is so deprived of fuel that it is completely unable to function.
Engine stalling can have dangerous consequences for vehicles and their driver, so if you notice any of the previously listed symptoms, you should check your vehicle’s fuel filter to help prevent stalling and other severe problems.
Solving the Problem
The simplest way to fix a clogged fuel filter is by preventing the problem in the first place. One way that you can do this is by scheduling regular maintenance appointments for your Volkswagen.
At these appointments, your mechanic will be able to check your vehicle’s fuel filter and replace it if needed. Experts suggest that Volkswagen owners have their vehicle’s fuel filters changed every 20,000 miles. So if it has been a while since your vehicle has been maintenanced, you should definitely consider bringing it in to a professional mechanic as soon as possible.
Of course, fuel filters don’t always clog at exactly the 20,000 mile mark. Sometimes they become impaired by debris much sooner. If this happens to your vehicle, do not attempt to solve the problem yourself. Your vehicle’s fuel filter is small, finicky, and vital to the engine’s functioning. As such, it should only be replaced by a trusted technician. If you suspect that your Volkswagen’s fuel filter is clogged, you should schedule an appointment with a mechanic sooner rather than later.
