Hi, I have a 650I E64. Unfortunately I got the message engine overheated. I found that the fan does not run at this time. Áb to the friendly and read out. They said that the fan would be broken. Engine started again next day (without climate) at about 80 degrees the fan went on and after cooling out and so on. When the gas was given the fan was also faster. ok, I thought, everything runs as it should be. I kept running the engine The temperature was so close to 120 degrees. Unfortunately, the fan does not start with the high theme ratings, even if I switch on the climate. So with normal temperature everything runs as it should be. The drop-out comes only when the engine is too hot. Does someone have an idea what this could be before I let the fan change and maybe this is not broken at all… thank you for the answers
