Audi A4 2.0T Quattro, I was driving my car the other day and fan heating everything was working fine, I parked the car went to do something for few hours came back turned the car on and fan is not working, so I started driving and after 10 minutes the fan started working and I could the breaks were tight when fan wasn't working and I could feel the breaks turning soft as the fan turned on. Anyone knows whats going on?
