I've got a standard OBD2 code reader (harborfreight top of the line from 3 years ago or so). It's allowed me to check and clear the generic codes I've had pop up over the years. Those were mostly misfires and the occasional "it took longer than expected for the coolant to warm-up". (Which usually
coincided with a sudden drop in outside temperature)

I was more worried about some other conditions that it might set that would require a BMW specific scanner
