DPF Warning Light On? What to Do Next
Seeing a DPF warning light illuminate your dashboard can be stressful. If you’ve also noticed your diesel vehicle has less power, is using more fuel, or producing excess smoke, a blocked Diesel Particulate Filter (DPF) is the most likely cause.
Before you consider an expensive dealership visit, it’s important to know what’s happening and how a specialist local workshop can solve the problem effectively.
What is a DPF and Why Does It Matter?
The Diesel Particulate Filter (DPF) is a critical component in your vehicle’s exhaust system. Its job is to capture and remove harmful soot from the engine’s emissions. Over time, this soot builds up. Under normal highway driving, the DPF gets hot enough to burn away the soot in a process called “regeneration.”
However, if you mainly do short, stop-start city driving, the DPF may not get hot enough to clean itself, leading to a blockage that requires professional attention.
Common DPF Problems to Watch For
A clogged DPF can cause a range of issues, from annoying to severe. The most common problems we see are:
- Blocked DPF: Soot accumulation triggers dashboard warnings and reduces engine power.
- Regeneration Failure: The DPF’s self-cleaning process fails due to short trips or sensor faults.
- Sensor Malfunctions: Faulty pressure or temperature sensors can send incorrect error messages.
- Excessive Fuel Consumption: A blocked filter forces your engine to work harder, burning more fuel.
- Limp Mode Activation: As a protective measure, your vehicle may enter “limp mode,” severely limiting engine power and speed.
