A bit of a update for you dirty diesel owners out there, the DPF delete MOT check could be changing. And soon.
February 2014, the kind people at VOSA added a visual check of the presence of a Diesel Particulate Filter (DPF) as part of the MOT. If you motor was missing one and it was built with one as standard, you weren’t getting your MOT.
So as a work around there have been a few tuning garages removing the internals and welding the DPF box back together. Which has been difficult to police, because if the box is present to pass the inspection they have to give you a MOT. So after a government investigation there are now urgent calls for reform as the current MOT fails to identify many cases of DPF removal.
Changes have this month been made to the Roadworthiness Directive legislation which will come into force in May 2018. This effects the smoke limit threshold, which is currently 1.5% to 0.7%, making it easier for MOT stations (and harder for tuners) to spot a potential DPF delete.
The Department for Transport (DfT ) says: “Removal of a DPF will almost invariably result in a contravention of the Regulations, making the vehicle illegal to use on the road. The legislation makes the owner or user of the vehicle primarily responsible for its condition. Whether the person who had removed the DPF, or had offered to remove it, had also committed an offence would be a matter for the courts to decide.”
Just so you are aware penalties currently stand at £1,000 for a cars and £2,500 for a vans
This could be something to bare in mind should you be considering the extra boost in performance.
