I have had my i3 REx for about a week now - great car - enjoying everything about it...well almost! As many US REx customers have reported I have the CEL issue. I dropped the vehicle off at my dealer in Los Angeles and I am now going into day 3 of the software update process. I guess I am not sure of all they are doing but I have heard that this update takes only two (2) hours. They are telling me they did their "part" now the BMW engineers in New Jersey need to do theirs. Seems like a very inefficient process and has me a little concerned that these software updates could become painful and I am sure we will have some along the way. Also, a little confused about the software update as the dealer was pretty vague about it - perhaps it is old news but I have seen some people have the CEL issue only to have it re-occur following their visit to the dealer. Does anyone know if I am getting THE "fix" or just something temporary. Thanks.
