It was another X5 E53 to be exact so another group 49 battery. I don't think the alternator is coming on line as I was able to start but only runs for 3-5 seconds before shutting down and lots of error codes.. This is a new vehicle to us and has sat for over a year. I finally have it in my car port so will get a better chance to check fuses, connections etc. Will report as I go through the systems. Thank you
