BMW 525 Forum : “temp. is not exactly right”

temp. is not exactly right

i own a 1994 bmw 525i manual, the temp. gage keeps telling me that the car is overheating, not drastically just a tiny bit, and its driving me crazy, i checked the fan belts, the fan's chutch, the radiator, the computer, the thermostat, the fuse responsible for the fan, and i change everything except for the computer!!!so please if you have any advice let me know...thank you
