From day one I've heard this pump/fan noise from under the engine and really never bothered about it as I was new to the car. Now the Mini is finished I thought I'd investigate the noise.
If I turn on the ignition but not starting the engine I can hear this noise. I found out it is the power steering pump working. I can tell because the steering is easy to turn. The pump seems to increase and decrease in speed without moving the steering wheel. The pump is basically running most of the time and sometimes not running resulting in no power steering.
So what controls the pump to make it work?
