Does removing a DPF have any impact on a cars emissions levels and will it affect the annual MOT test?
I know if I took off a Catalyst from a petrol engine the chances are it will fail the emissions test but do DPF's have the same effect as they just filter out the particles?
THE UK MOT RULES CHANGED IN FEB 2014, so some of the older posts in this thread may therefore be inaccurate. DPF REMOVAL is an instant failure if spotted by the tester.
