My engine shuts off while. Driveing and says no signal

Hello, what says "no signal"? It's nearly impossible to sit at my computer and guess what's wrong with your vehicle with almost no information. And even with more information, hands on testing by someone with the ability to perform diagnostic testing using a BMW capable tool and have the availability of workshop manuals on hand is really what you need.
