DPF Cleaning

The Diesel particulate filter (DPF) is part of the exhaust system on modern diesel cars tasked with the job of catching particulate matter (PM), various sensors moniter the Dpf and activate a regeneration when required, this is the process where the particulate matter is burnt off to prevent over filling and blockage.

This should happen automatically when driving without any driver input, your vehicle will identify when regeneration is needed and make alterations to the engine management system to increase the temperature of the DPF till the PM is reduced to an acceptable level. However Should your vehicle develop a fault or be incorrectly serviced regeneration may not take place resulting in warning lights coming on, loss of power and even not starting or driving.

Autotec Northwest have a multi-stage treatment to unblock DPF filters and specialist diagnostic, training and testing eqiupment to determine the cause of the blockage.

A blocked DPF is almost always the results of a fault, cleaning a dpf without finding the underlying issue will only result in further blockages and wasted money.

Before cleaning a DPF Autotec Northwest will carry out an assesment to determine the cause of blockage and warning lights being activated, in many cases the DPF may not need to be cleaned just the cause rectified and a regeneration activated.
