Diesel Particulate Filters (DPF) – now part of the MOT test AND an offence not to have one

We get lots of complaints from customers who have failed to “regenerate” their DPF causing it to block with soot and thus preventing it from working.  This has resulted in many people often removing the filter as opposed to having it cleaned or replaced.

However, from next month (February 2014) MOT’s will include a check to see if the filter is present and if it is not the vehicle will fail its MOT (provided the vehicle was built with filter in situ).

The purpose of the DPF is to reduce harmful exhaust emissions into the atmosphere.  Where it is removed, the vehicle will almost certainly contravene the Road vehicles (Construction and Use) Regulations.  The potential penalty for such a contravention is a fine of up to £1000 for a car and £2500 for a light goods vehicle.
