Hi guys, I have a X3 E83 30d year 2009 automatic, in this car when engine start go on the cooling fan to max, I have replace cooling fan, but always same problem, I have replace engine temperature sensor but always same problem, I have replace ecu engine (cloned), but always same problem, when engine start cooling fan go to max, in diagnosis temperature is ok if disconnect sensor temp I have error and temperature is wrong, I dont' know what can to be, I have seen when ignition lock is to +15 before start engine the shutter of cooling fan is all open also with engine cold, someone has had this problem?
Thanks in advance
