What Is a DPF?
A Diesel Particulate Filter (DPF) is fitted to modern diesel vehicles to trap soot from the exhaust system. Under normal driving conditions, the vehicle burns this soot off during a process called regeneration.
However, if the vehicle is mainly used for short journeys, has an engine fault, faulty sensor, low temperature issue, EGR problem, boost leak, injector issue or incorrect oil, the DPF can become blocked — causing the vehicle to lose power, enter limp mode or display warning lights.
Common Signs of a Blocked DPF
You may need DPF diagnostics or cleaning if you notice any of the following.
If your DPF warning light is on, it is best not to ignore it. Continuing to drive with a blocked DPF can lead to further damage and higher repair costs.
DPF Cleaning Is Not Just About the Filter
A blocked DPF is often a symptom of another problem. Simply cleaning the filter without finding the cause can mean the same fault returns shortly afterwards.
We check the system properly, including live data and related components, to help find out why the DPF blocked in the first place. Depending on the vehicle and fault, we may check:
- DPF soot and ash levels
- Differential pressure sensor readings
- Exhaust temperature sensor readings
- EGR operation
- Boost pressure and air leaks
- Injector correction values
- Engine temperature and thermostat operation
- Glow plugs and regeneration conditions
- Oil level and oil contamination
- Relevant wiring, sensors and control module faults

Frequently Asked Questions
Can you just clean the DPF without diagnosing the cause?
We don't recommend it. A blocked DPF is often caused by an underlying engine or emissions fault. Cleaning the filter without finding the root cause usually means the problem returns. We always check the full system first.
Will a forced regeneration always fix a blocked DPF?
Not always. If the filter is too heavily blocked with ash or there is another serious fault present, a forced regeneration may not be the correct option. We'll assess the situation and advise you honestly before carrying out any work.
Do you work on fleet and commercial vehicles?
Yes. We understand that a DPF fault on a fleet vehicle or work van needs resolving quickly. We work with private customers, tradespeople and businesses, and aim to turn repairs around as fast as possible.
