We’ll carefully assess any DPF issues to determine whether a professional clean will solve the problem or if repair or replacement is the better option. With our extensive industry knowledge and experience working on diesel vehicles, we’ll guide you clearly and confidently toward the most effective next step. Our diagnostic equipment is continually updated to ensure you always receive the most accurate advice.

Once the diagnostic checks have confirmed the precise cause of the fault, we may recommend cleaning the throttle body if it is identified as contributing to the issue. The throttle body controls the airflow into the engine—something that’s essential for proper DPF regeneration and overall engine health.

Using specialist cleaning solutions, we aim to restore the throttle body to optimal condition. After cleaning, we carry out a thorough diagnostics test to ensure your vehicle’s performance remains smooth and efficient. By removing carbon and debris from the throttle blade and bore, we help improve power delivery, responsiveness, and engine cleanliness.

Through our diagnostic checks, we can determine whether your DPF is blocked or partially restricted—even if the Engine Management Light (EML) hasn’t come on. When needed, we can run the engine at a carefully controlled high temperature, combined with our specialist cleaning equipment, to safely force a regeneration cycle.

Although this process can take some time and may require following manufacturer guidelines for extended driving, it remains the recommended and most trusted approach across the industry.

Connection to our DPF Cleaning machine which uses pressurised air and specialist cleaning fluids to clean the DPF system; In rare cases, a DPF may become so heavily clogged or blocked that regular cleaning or regeneration is no longer effective, leaving the DPF on your vehicle, we use 2 types of specialist DPF fluid which are fed through the DPF using our pressurised air machine. All of this work occurs with the DPF in situ and is very effective for lots of our Customers and delivers the result required. This is most effective when the DPF is near-wholly blocked and previous repair options have been unsuccessful.

This thorough approach is the final repair option before considering a full DPF replacement, and we only recommend it when absolutely necessary.

A final approach to heavily clogged/ blocked DPF is to remove the DPF from your vehicle and connect to a specialist machine pressure clean. This is a much longer process and involves further specialist cleaning additives are used to break down the blockage.
