Had similar problem with a '90 M104. First, be careful with lowering temp as it could affect emissions(87C is ideal). Second, my engine would go 100C+ in the summer months until I did the resistor trick (search here for resistor+temperature, should get it) which kicks on the electric fans earlier. It will now control at approx. 93 deg. C
