Mark, based on past experience I always carry a code scanner with me, just in case, and a set of tools. My X5 only has about 70K miles on it, but you never know what could go wrong on the road. Let me know if you need any assistance, as I can call you and help you troubleshoot the problem. Send a PM any time and I'm here to help.
Good luck!
Mike
