P0128 thermostat blow regulating temp.

Has anyone else experienced this problem?

I have already replaced the thermostat a little over 2 months ago.... The light came back on after 2 months same code. This time I was told its the water pump I replaced that 2 days ago and ses light is back on same code. What else could it be? Mind you this work has all been preformed by BMW! So very expensive.
