1996 C220
My 96 C220 check engine comes on when temperature goes 80C and above. Engine run fine and temperature stay between 80 to 85. Recently I changed water pump and nothing else. I am quite sure that is related to water temperature because if I let it run, before reach 80C the check engine would not light. (I reset the memory by pulling the fuses). I appreciate if somebody helps me in this matter.
Thank you all.
For your additional information, my 95 C200 have day to day temperature is 80 to 85C.
Regards,
Robby.
