One-off treatment for blocked DPFs

DPF Deep Clean is a professional workshop treatment designed to clean Diesel Particulate Filters that have become blocked due to a build-up of soot. It is a much cheaper solution than replacing the DPF.

This treatment will include a direct flush into the DPF followed by a diagnostic regeneration of the DPF to reset the engine management system and finally a test drive of at least 20 minutes.

In some cases the cause of the blockage can be the incorrect oil grade being used In the vehicle. If it is unclear what grade of oil has previously been use we will recommend an oil and filter change at the same time and this will be quoted for as necessary.

If, on one of those very rare occasions, it fails to clear the filter we will need to remove it completely from the car and soak it overnight and then flush it through. This work will need to be quoted for individually as all vehicles will vary in the length of time this will take.


These deep clean treatments are guaranteed to work on over 95% of cars, dependent on the level of soot and the condition and age of the filter, saving you a lot of money compared to a new filter. If however it doesn't work we'll take the cost off the DPF replacement, assuming we do the replacement for you.
