Diesel Particulate Filter (DPF) Cleaning

Our fully trained and team of engineers offer a bespoke DPF cleaning service to ensure your DPF is operating at the optimal level of efficiency.

A diesel particulate filter (DPF) is designed to capture the excess soot particles from a diesel exhaust. If all the relevant sensors and parts required are functional, the DPF will attempt to clean itself by ‘regenerating’ when the car reaches a certain temperature. This is usually achieved on longer journeys. If a car is mainly used for short or stop/start journeys, the temperature to successfully regenerate cannot be reached. This over time causes the DPF to clog up, be unable to regenerate and clear the soot. As well as suffering a likely reduction in power and increase in fuel consumption, it could result in the back pressure from the DPF causing catastrophic damage to the engine and in some cases will stop the engine from running or even starting.

We will only recommend a DPF clean after conducting full diagnostics to ensure we can identify what is causing the DPF problem. Once all checks are completed and we are satisfied we then can safely proceed and carry out the DPF Clean and Flush.

We recommend carrying out an Engine Carbon Clean in addition to ensure the vehicle is running at its best.


Wrighthands-engineering will not be held accountable for worn or broken parts on the vehicle. Regular servicing should be carried out on the vehicle to keep the engine running smoothly and efficiently. We will carry out a visual safety check and a full diagnostic check which is included in the price of the engine cleaning process.

Wrighthands-engineering will inform the customer of all diagnostic reports and will not carry out either a Carbon Engine clean or DPF Clean unless it’s safe to do so.

All our technicians are fully trained and fully insured for your peace of mind.
