my project in danger

NO one ever looks to see what type of engine you have after an accident???
my everyday car is a Peugeot, at the last annual technical check I failed because my "certificate of conformity" issued by the manufacturer is very slightly torn.
I must ask for a new one at 250 euros.
if I get arrested for an inspection or if I have an accident, it is automatically involved because my last inspection is recalled because of a slightly torn document !!!
