I have a GT3RS V2 wheel that I started using about a week ago (including the Clubsport pedals). I updated the firmware a few days ago with the 681 revision and followed the installation instructions, and the installation was successful on the first try. The first problem after the firmware update was the apparently very common problem of the wheel losing its centering very quickly. It got so bad that when I used the wheel in GTR Evolution and GTR2, it would lose its centering in less than a minute after getting on track. I followed all calibration instructions many times but this did not help. And yesterday, another serious problem started. After it goes through its power-on self calibration, if you turn the wheel at all it physically pulls itself back to the center. This happens immediately after powering the wheel up, without even loading any racing sim software. If you turn the power off the wheel seems to turn as it should. I've uploaded a video showing this problem, here: * http://www.flickr.com/photos/24899245@N07/5232312452/ I'm posting this problem here because I'm not sure how to even proceed. The wheel is obviously malfunctioning and needs to be returned and replaced. I'm hoping that Brian, who is very helpful with Fanatec issues, can contact me here or via email at email@example.com as quickly as possible, it will be appreciated (I have also posted about this problem on the Porsche 911 Wheel Fan Club forums to see if Fanatec support replies). The wheel is completely unusable at this point.
