I read your post on the SMG failure and it looks my M3 is howing the same symptoms as your girls car. A few weeks back I was driving in 94 degree weather and both the SES and SMG COG light went on. I took it to an IndI shop and ran the codes which brought up Hydralic pump and temp sensor. The car only shifted the gear in N one time while driving. And my first thought was to change the salmon relay like many others have told me to try first which I did. And so far no problems it runs fine, however I do notice that the headdash tempeture often goes up and down which is not normal. Do you recommend be just replacing the pump or wait it out till it actually fails? I took the car back from the Indi shop so that I can start saving money for the Pump. My friend works at a BMW dealer and quoted me exactly the same price you paid $1900. Any advice? What do you think about adding the heat resistor sensor?
