If you own a modern diesel vehicle, chances are it’s fitted with a Diesel Particulate Filter (DPF). This vital component is designed to capture and store soot particles from your exhaust, preventing harmful emissions from being released into the atmosphere. But like any filter, a DPF can become blocked over time, leading to poor vehicle performance, warning lights on your dashboard, and potentially costly repairs.
At DPF Cleaning Experts, we know how stressful it can be when your vehicle shows signs of a blocked filter. That’s why we’ve put together this guide to answer one of the most common questions we hear: “How do I deal with a blocked DPF?”
Recognising the Signs of a Blocked DPF
A blocked DPF won’t go unnoticed for long. Some of the most common symptoms include:
DPF warning light illuminated on your dashboard.
Loss of power or sluggish acceleration.
Increased fuel consumption.
Unusual exhaust smoke or smells.
Poor engine performance or the vehicle going into “limp mode.”
If you experience one or more of these symptoms, it’s essential not to ignore them. Driving with a blocked DPF for too long can damage the filter and engine, resulting in expensive repairs or even the need for a full DPF replacement.
Why Do DPFs Become Blocked?
Your DPF is designed to regenerate – burning off the built-up soot during longer drives at higher speeds. However, several factors can prevent this natural regeneration process:
Short, stop-start journeys that don’t allow the exhaust to reach the required temperature.
Poor-quality fuel or incorrect engine oil.
Faulty sensors or EGR valves that affect regeneration.
Neglecting regular servicing.
Understanding these causes can help you avoid recurring DPF problems in the future.
How Do I Deal With a Blocked DPF?
When asking yourself “How do I deal with a blocked DPF?”, there are a few steps to consider:
1. Don’t Ignore the Warning Signs
If the warning light appears, take action immediately. The longer you drive with a blocked filter, the more soot builds up, and the harder it becomes to clear.
2. Try a Regeneration Drive
If the blockage is light, taking your vehicle on a sustained motorway drive at higher revs may allow the DPF to regenerate and burn off soot. However, this only works in minor cases and won’t resolve heavy blockages.
3. Avoid DIY Additives and Quick Fixes
Fuel additives and “miracle cures” may claim to clean your DPF, but in most cases, they only provide temporary relief. Worse still, they can mask the problem without addressing the underlying cause.
