2003 Other Audi Models 6 cyl All Wheel Drive Automatic 88,000 miles
Car is 2003 Audi Allroad 2.7 Twin Turbo. Aux. Fan in front radiator would squeal when ever you turned the heater fan on. Installed new aux. Fan and noise is a little quieter but still there. As soon as you turn on the heater fan the aux. Fan engages and squeals, it also will cycle on & off every minute or so. There seams to be a very minor oil leak from the A/C compressor. What would be causing the squealing & should it cycle as often as it does?
