To RichardPalinkas im not going to carry on about this any further but all you are doing now is agreeing with exactly what i been saying in my last post thats what ive been saying , the Tech2 unit is used first to diagnose the fault then the repair is done thats how its normally done... learn to read the post correctly before passing on your uninformed opinion and then agreeing ..because the forum his here to help people with problems not create confusion
