I reviewed the Foxwell NT510 and watched a few video reviews by some BMW owners. It’s about $240 in Canada on Amazon.ca but I think it’s probably the best and worth it considering it will do just about anything a BMW dealership can do. According to my research some BMW owners have recommend BMW Scanner 1.4 (OBD Connector with cable to connect to laptop). There is another scanner on Amazon called ANCEL BM700 All System for BMW & Mini vehicles with very good reviews.
