DPF warning light on? Regeneration failing? Vehicle in limp mode? We assess the cause first — then recommend the correct cleaning or repair route.
Don't just clean it — diagnose it
A blocked DPF is often the result of another problem, not the original fault. Simply forcing a regeneration or replacing parts without testing can leave you with the same warning light again.
At SX Customs we start with a proper DPF assessment, looking at the vehicle's fault codes and live data before deciding what it actually needs.
Our aim is to identify the cause, protect the DPF and avoid unnecessary parts replacement.
Our process
We scan the vehicle and check the data that affects DPF operation, rather than assuming the filter itself is the only problem.
We determine whether the DPF is suitable for regeneration or cleaning and identify faults that need addressing first.
Where suitable, on-car DPF cleaning can be carried out. We then recheck readings and confirm the vehicle's response.

Common symptoms
If a fault is preventing regeneration, that issue should be identified before repeated cleaning attempts.
Recommended next steps
Diagnostic scan, live-data assessment and checks to establish why the DPF warning or blockage has occurred.
Where the filter and vehicle are suitable, professional on-car DPF cleaning can be recommended and carried out.
Sensor, airflow, EGR, boost, temperature or engine-related problems can prevent successful regeneration and need correcting first.

DPF questions
Yes. Where the vehicle and filter are suitable, on-car DPF cleaning can be used. The assessment determines whether this is the appropriate route.
Only if the underlying cause is also dealt with. A sensor, engine, EGR, boost or regeneration fault can cause the DPF to block again.
Yes. We use fault codes and live data to investigate why regeneration is failing or happening too frequently.
Yes. The Basildon workshop operates by appointment only so we can allocate the correct diagnostic time to the vehicle.
