Our proven DPF process
A blocked DPF is almost always a symptom of an underlying engine fault. At SSER Automotive Solutions in Eccleshall, we don't just clear fault lights or flush filters. We diagnose the root cause, professionally machine clean the unit, and resolve underlying faults so your vehicle stays reliable on the road.
Step 1: In-depth root-cause diagnostics
Before removing any exhaust components, we carry out a thorough diagnostic assessment using advanced diagnostic equipment and up-to-date software. We also conduct a road test where safe and appropriate, allowing us to assess the vehicle's performance, monitor live data and identify faults under real driving conditions.
We investigate common causes of DPF blockages, including faulty pressure or temperature sensors, clogged EGR valves, defective fuel injectors and failed regeneration cycles.
By understanding why the DPF became blocked in the first place, we can address the underlying issue rather than simply providing a temporary fix, helping reduce the risk of future blockages.
Step 2: On-Car or Off-Car Specialist DPF Cleaning
Following our initial diagnostic assessment, we determine whether on-car or off-car DPF cleaning is the most suitable solution for your vehicle.
Where appropriate, we carry out on-car cleaning without removing the filter. For more severe blockages or where deeper cleaning is required, our technicians carefully remove the DPF and use our specialist industrial cleaning machine to remove built-up soot and non-combustible ash.
We assess the filter's condition and, where applicable, compare pressure and flow readings before and after cleaning to evaluate the results.
Our approach ensures each vehicle receives the most appropriate cleaning method based on its condition and underlying fault.
Step 3: Precision refitting, testing, and handover
We reinstall your cleaned DPF alongside any agreed repairs to injectors, sensors, or intake systems. After refitting, we reset adaptation values, conduct live data road tests, and verify system pressures to confirm optimal exhaust flow. You receive clear before-and-after flow results along with tailored driving advice to help prevent future blockages. Trade and fleet collection or delivery is also available across Staffordshire.
