Stop guessing. Start measuring.
A DPF warning light does not automatically mean the filter needs replacing. A completed regeneration does not prove that the filter is retaining particles effectively.
DPF Check focuses on the practical question: is the filter doing the job it was designed to do?
The dedicated tester checks for particles that should be captured by a properly functioning DPF. It can identify a compromised filter at idle in approximately 30 seconds or less.
Why DPF diagnosis is difficult
Customers can arrive with warning lights, reduced power, repeated regeneration, increased fuel consumption or inspection concerns. These symptoms can arise from numerous causes, including sensors, driving pattern, engine condition, turbocharger faults, EGR problems or the filter itself.
Fault codes and pressure data are useful, but they do not directly prove filtration efficiency. DPF Check adds a direct assessment of particles leaving the exhaust.

What a DPF efficiency check can answer
- Is the DPF retaining particulate matter effectively?
- Does the result indicate healthy, marginal or poor filtration?
- Is further investigation required?
- Has a repair or replacement improved the result?
- Can the workshop give the customer evidence before recommending expensive work?

Better customer conversations
Support recommendations with evidence.
Reduced misdiagnosis
Separate DPF efficiency from symptoms that may originate elsewhere.
Distributor fit
Position with diesel diagnostics, emissions equipment and training.
Technical support

Important limitation
A poor result identifies the need for further investigation. It does not by itself confirm whether the cause is physical damage, tampering, engine condition or another emissions-system fault.
Frequently asked questions
Is this the same as a smoke test?
No. It is designed specifically to assess particles that should be retained by a functioning DPF.
How long does the test take?
A result can be produced at idle in around 30 seconds or less once the test is ready.
Does a poor result mean the DPF must be replaced?
Not automatically. A poor result means further diagnosis is required.
Can results be shown to customers?
Yes. Tablet-supported testing can provide graphical information, records and printing.
Using the result responsibly
A GOOD result
A good result indicates that the measured particle level is consistent with effective filtration under the test conditions. It does not confirm that every part of the engine and emissions system is fault-free.
A MARGINAL result
A marginal result should prompt careful review, repeat testing where appropriate and consideration of vehicle condition, test procedure and supporting diagnostic information.
A POOR result
A poor result indicates that filtration efficiency requires investigation. Possible causes include physical filter damage, tampering or another system problem. Replacement should not be recommended without appropriate diagnosis.
Repair validation
Testing before and after suitable work provides a clear way to demonstrate whether particle performance has improved. This gives the workshop and customer useful evidence and helps protect both parties from assumption.
