While you are in the "01.xx menu, press and hold the milage reset button again for a few seconds and you will see the "01.xx menu again. Now quickly within a second press and release the reset button 18 more times to get to the menu item number "19 - Unlock". Wait a second or two and you will be prompted to enter the unlock code which is the sum of the number listed in "01.00". To enter the code, press and release the reset button until you arrive at the unlock code number. At this point the menu is unlocked and you can scroll with the reset button to number "07.00" which is the coolant temperature. I only drove for a few miles, but it continued to display while driving and read between 91 and 106 degrees C. I will drive it harder tomorrow and see where I can get it to read.
thanks, I was under the impression that this procedure doesn't work on e9x but I'll give it a try!
