Citroen C3 Picasso has failed its MoT on emissions

My 2009 Citroen C3 Picasso 1.6 diesel has just failed its MoT on emissions. The garage has told me that I don’t do enough miles. For a retest I must drive it around for a few hours in third gear and leave it running when they test it again. Is this usual practice?

They told me I probably need a new converter. As you can expect I am very worried as it has only done 28,000 miles and I do take it out for long runs from time to time. Can you help?

Wrong engine for short run use. Yes, the way to prepare for a diesel MoT is to put a can of fuel system cleaner into the tank, fill up with Shell V-Power Nitro Plus and take the car for a 50 mile run bringing the revs up to 4500 occasionally because that is what they have to do in the MoT test.
