Diesel particulate filters (DPFs) have become a critical component of modern diesel engines aimed at reducing the emission of harmful particles into the environment. But like any other part of a vehicle, these can become blocked, causing adverse effects on the engine’s performance and requiring DPF cleaning. In today’s article, we will discuss three ways to know if your diesel particulate filter is blocked:
The most common way to know your DPF is blocked is through a warning light on your dashboard. This light is often shaped like an engine and is usually amber or red, depending on the severity of the blockage. The light is programmed to appear when the filter is partially blocked and needs cleaning. If you ignore the warning light, the blockage will increase, and the light will turn red. Take immediate action to avoid engine damage.
It’s important to note that not all warning lights on your dashboard are related to the DPF. So it’s crucial to consult your owner’s manual to determine the meaning of each light. If you’re uncertain, it’s wise to take your vehicle to a qualified mechanic to diagnose the problem accurately.
Loss of Engine Power
A blocked DPF can also cause a significant loss of engine power. This occurs because the filter restricts the exhaust flow, which affects the engine’s combustion process. You may notice that your vehicle takes a while to accelerate, struggles to maintain speed, or even stalls when this happens. In severe cases, the car may go into “limp mode,” where it will not exceed a specific speed limit, usually around 40 mph.
If you observe a sudden loss of power, you must check your DPF immediately. A blocked filter can damage your engine and other components, leading to expensive repairs. A regeneration process or DPF cleaning may sometimes fix the issue, but if the filter is too blocked, you may need to replace it altogether.
Unusual Smells and Noises
A blocked DPF can also cause unusual smells and noises. When the filter becomes clogged, it can affect the entire exhaust system, leading to unpleasant smells and noises. You may notice a strong smell of diesel or a burning odour, which could indicate that the DPF is overheating. Sometimes, you may hear a rattling or banging noise when you accelerate, possibly due to a damaged or broken filter.
Immediately take your vehicle to a qualified technician if you notice unusual smells or noises. These symptoms could indicate a severe problem that requires immediate attention. Ignoring them could cause further damage to your engine and other components, leading to expensive repairs.
