I know nothing of BMWs but in any car ive has the EM light on this was the case, although it took ten or so miles of driving before it cleared
Usually these sort of things turn themselves off after a certain amount of "good" ignition ons.
I bought a USB cable a fortnight ago from a well known online marketplace for less than 18 quid inc delivery (CAR PC DIAGNOSTIC SCANNER FAULT CODE READER ELM 327 OBD) and it came with Proscan software similar to Vagcom, so far it has worked on my newage WRX and the wifes 4.6 IS v8 X5. Definately worth the money matey.
