Paul,
Some say the 5 WOT trick works on cars up to '95 MY, but I could never get

Other than that, ask to borrow a Peak-style code reader/resetter from one 
of your local BMW CCA chapter members. Or buy one yourself:

Was it low? Did you add more coolant?
Could be a flaky switch, could be low coolant that expands when warm.

Good for you. 
Now read the CE code, fix the problem, reset the light.
