Yes, agree with DSE, get a video camera and take pictures of the codes and problems as they come up ..I did this and it was really helpful to prove that there were real problems rather than the dealer trying to replicate them in their own time ..and often with gremlin electric problems they can be there one moment and not the next (typically there for you but not the dealer/mechanic etc)
