Interesting comment about recent Logitech update from Geoffers, although I am not sure if the G25 still qualifies for updates?
Besides this weird steering problem I was effectively dropped from a GPL race last Tuesday because I simply could not select any gears. The steering worked ( not sure about the "delay" issue as I was more focused on the gearbox issues ) the pedals worked, but no gears could be selected.
I spent quali on a panicked recalibration of the Bodnar cables, and also within GPL, that achieved nothing. With a few minutes left, I even disconnected the Bodnar cable from the shifter, unscrewed the wheel from my rig and re-connected the shifter to the Logitech socket ....re calibrated etc and..... nothing!!
Eventually I had to delete my controls.cfg file in my GPL player directory and allow the game to rebuild the file. Too late to join the GPL race but a problem that I have never had before. Update related?? I don't know.
I think a strip down and clean is the first job and the easiest. Failing that, the harder job might be building a convincing business case for the purchase of a new Fanatec wheel
