Would be handy to know what the mot test results are from the test sheet before making conclusions.
ok results hope it means something to you .at idle 0.40 and while revving 0.60,over here the maximum is 0.30 at idle and 0.30 while revving this the best way i can describe
I think the Redex one is just a carb and injector cleaner. There are some additives specially targeted at emmissions. Something like "liquido speciale para la reduzione des emissiones" maybe. My Spanish always tries to turn into Italian...........
may sound like its longer than a day without food, but as from tomorrow i have days without car,i tried bribery at test centre,wasnt having it, will just have to leave it in the hands of diego el mecanico
