I have a 2007 vauxhall zafira 1.9 cdti, do you no if I replace one of the injectors will it need coding? the injector is a second hand one if that makes any difference? Thanks
Ideally the code on top of the injector should be coded in,probably by Tech2,I know of different makes where it is essential for good running,have done other models of Vauxhall without doing this and they seemed to run ok,good luck.
