The catalyst component of a Diesel Particulate Filter (DPF) can be damaged by poisoning (for example sulphur poisoning) major engine failures or by physical damage to the exhaust system.
This damage may not be apparent but reduced catalyst activity can limit the DPF system’s ability to regenerate and can result in frequent blocking of filters.
Our specialist catalyst testing equipment can check the activity level of a catalyst to identify any problems. This testing can be carried out at your premises or at our Customer Service Centre. If required, replacement catalyst sections are available that can return the system to normal operation and improve filter service intervals.
