From February 2014 the inspection of the exhaust system carried out during the
MoT test will include a check for the presence of a DPF. A missing DPF, where one
was fitted when the vehicle was built, will result in an MoT failure.

Although happy the issue is settled now, two things spring to mind:

Firstly, what criteria will the check for the presence of a DPF be?

A visual check for pressure pipe & heat sensor? .. .. .. Oooops
Some cleverly hidden ‘cutting & shutting’ will disguise the fact the can is empty.

A diagnostic check for data? .. .. .. Oooops
Who makes a tool that will read DPF data on all relevant vehicles?

Secondly, Who is going to compile the list of affected vehicles?

To name a few, Peugeot, Vauxhall, Ford & VAG have made the same model with and without DPF as O.E.
