I replaced my E90 335i battery with the same CCA and such from Interstate Battery. No coding or anything and it was all fine for about a month i drove. Car was in at an indy shop for service and asked the tech to program it, he tried and it didnt work for some reason but he did say as long as its the same or better than OEM it will be fine, he said he never codes his new batteries. This is a very known local European car shop, so i left it uncoded and nothing happened.
