I own a BMW 740i (99). I was exiting onto the highway and merging into middle lane when my car just stopped cold on the highway. I was so worried about being killed as the cars were flying at 80 by me. I did have a message but was too busy to worry about my life. I did receive a service engine soon light. I did have my car towed to my building because it was Sat evening. I am bringing it on tomorrow -- any ideas what might be wrong? Thanks!
