The primary cause of the diesel particulate filter (DPF) warning light display is a blocked particulate filter. The warning light signifies that the onboard computer system has detected excess soot build-up in the particulate filter, which is liable to trigger limp mode.

When this warning light displays on your dashboard, it generally means that your vehicle’s diesel particulate filter (DPF) is clogged. While this type of anomaly should not be taken lightly, several solutions exist to put it out before calling in a professional.

DPF warning lights might be solid or flashing when they come on, indicating two different concern levels. And there are two ways to regenerate an engine. Let’s walk through it.

Sep 8, 2016 · The diesel particulate filter light turns on when the soot level from the diesel exhaust is high and your car is at risk of going into limp mode.

May 28, 2024 · A clogged diesel particulate filter (DPF) is the main culprit behind the DPF warning light. When this light comes on, it means that the onboard computer has identified too much soot in the particle filter, which could cause limp mode to be activated.

May 6, 2019 · A flashing orange DPF light (or whatever the primary activation mode is) just tells you that the filter is getting loaded up, and a burn or regeneration is necessary and/or overdue. The car knows this because it measures the pressure drop across the DPF.

Mar 9, 2023 · When the DPF filter gets blocked or clogged, the engine becomes weaker and a check engine light often shows on your dashboard. It can also lead to higher fuel consumption and create a hard-starting situation. Additionally, you may also notice strange smells or turbocharger issues.

Oct 26, 2023 · Why Does the DPF Light Come On? A diesel particulate light illuminates to inform motorists that an engine’s passive regeneration has failed, thereby signifying the need for active regeneration. A DPF utilizes a series of pressure differential switches and backpressure sensors to determine soot loading.

The warning light indicates your vehicle’s inability to let go of the accumulated soot, which is one significant sign that it is now your turn to do something about it. How can you fix the Problem when the DPF Warning Light appears?

Aug 1, 2024 · Seeing that dreaded DPF light illuminate on your dashboard can be a cause for concern for any diesel car owner. But don’t panic! Understanding what the DPF light means, its causes, and how to prevent it from becoming a major issue is crucial.
