I have had a search but cant find a definitive answer. I know that it is a common problem on the A3's (I have a 2.0tdi 2004) for the fan to run constantly, and make a hell of a racket. I was just wondering do i have to replace the fan unit, or can i just replace the control unit? Is the P/N for the unit 1J0919506K, if not does someone have the part number i need, and how easy is it to change?
Thanks
