recently i have noticed my fan has been running after the engine has been stopped.. sometimes it will start when the car hasn't been driven that day and is parked up and locked. It was intermittent to start with but is now getting more common and today it did it whilst i was at work and flattened the battery!
I have done a scan with VCDS and it brings up fault code 18009 - Implausable signal to relay j317. Position 30.
Im not really sure what this means or how to go about fixing it but obviously it needs fixing asap so if anybody can help i'd greatly appreciate it.
Thanks in advance
