Before buying and installing a new aux fan, you should verify that it is the fan. There's a 50 amps fuse behind the glove box, if that is blown you can bet your sweet dollars that the fan is also bad.
If you have access to BMW software you can see if there's a fault code for the fan. The DME commands the fan to spin and when the fan is freewheeling it sends back voltage to the DME. The DME sees this voltage and knows that the fan is O.K.. If the DME doesn't see this voltage the DME knows that the fan is not turning.
No my X does not make any rackets when I crank it.
