I am sure the Fan that installed by BMW personnel is good, because I test it with a Squarewave pulse and the fan is working the car was arrived late in night yesterday so I am not able to check the sensors I will check it tommorrow and some advise from the members of this forum. Thanks for all suggestions.. I will report tomorrow night the result |
