strange issue with radiator fan
Hey, I have a strange problem with the radiator fan on the E92 328i (2009) (N52B30) , I have searched all possible forums, and have not come across such a case:
The engine heats up to a temperature of 93 degrees (water in the engine block), then the fan is started, which works at constantly higher revs and maintains the temperature in the range of 90-93 degrees, turns off only after turning off the engine, after starting it again after reaching 93 degrees start up again ... There are no errors under the computer, all modules are green in ISTA. I have no ideas what could be the reason ... By the way properly working temperatute should be higher then 93 degrees.. Before this issue, radiator fan was start at 108 degrees an after few seconds temperature dropped to 103-104 degrees (at a standstill) - so i think it was the correct cycle |

Hi, i know that, but daily i dont turn on the AC, in my country now is 10-15 degreee, so the electric radiator fan should't be active when the engine temperature is 90 degree
