FAQ's
1. What is a DPF and what does it do?
A Diesel Particulate Filter (DPF) is an exhaust component that traps soot and fine particles produced by diesel engines. Its job is to reduce emissions by capturing soot and burning it off during regeneration. Over time, especially with short journeys, the DPF can become blocked and require professional cleaning.
2. What causes a DPF to become blocked?
A DPF usually becomes blocked due to:
✔ Short journeys that prevent full regeneration
✔ Stop-start or urban driving
✔ Failed or interrupted regeneration cycles
✔ EGR faults or sensor issues affecting combustion
✔ Excessive soot production
In most cases, a blocked DPF is a symptom of an underlying issue, not the fault itself.
3. Can a blocked DPF be cleaned or does it need replacing?
In many cases, a blocked DPF can be professionally cleaned rather than replaced.
If the DPF is structurally intact and not cracked or melted, cleaning is often a safe and cost-effective solution. Diagnostics are always carried out first to confirm whether cleaning is suitable.
4. How do you diagnose DPF problems?
DPF diagnostics involve checking:
✔ Fault codes and warning messages
✔ Live exhaust pressure and temperature data
✔ Regeneration status and history
✔ Related systems such as the EGR
This diagnostic-led approach identifies whether the DPF can be cleaned and what caused the issue in the first place.
5. What are the symptoms of a blocked DPF?
Common blocked DPF symptoms include:
✔ DPF or engine management warning light
✔ Limp mode or reduced power
✔ Poor fuel economy
✔ Sluggish acceleration
✔ Regeneration warnings or messages
✔ Excess exhaust smoke
Driving with these symptoms can lead to further engine and exhaust damage.
6. What is hydrogen cleaning and does it help with DPF problems?
Hydrogen cleaning is a carbon cleaning process that removes built-up carbon from the combustion system.
It helps by:
✔ Improving combustion efficiency
✔ Reducing soot production
✔ Supporting healthier DPF regeneration
✔ Helping keep combustion components cleaner
Hydrogen cleaning works best as part of a wider diagnostic and maintenance approach, not as a standalone fix.
7. Can EGR problems cause DPF issues?
Yes.
A faulty or carbon-restricted EGR system can increase soot production, which can overload the DPF. This is why, when assessing the DPF we look at a number of other functions like the EGR systems during the diagnostics.
8. How long does a DPF clean take?
Most DPF cleaning jobs take between 1 and 2 hours, depending on the level of blockage and vehicle condition.
Before-and-after diagnostic data is used to confirm reduced back pressure and successful cleaning.
9. Is DPF cleaning safe for my engine?
DPF cleaning is safe when carried out correctly and only when the DPF is suitable for cleaning.
If a DPF is cracked, internally damaged or beyond recovery, cleaning will not be recommended.
10. How can I prevent future DPF and other related problems?
You can reduce the risk of future issues by:
✔ Allowing regeneration cycles to complete
✔ Avoiding repeated short journeys where possible
✔ Keeping on top of servicing
✔ Acting early when warning lights appear
✔ Using hydrogen cleaning periodically to reduce carbon build-up
Early diagnostics are key to avoiding expensive repairs.
