Fed up with cleaning my G25/G27 pedals at long last have fixed by installing Halls sensors, the kit was obtained from Simulaje costing 45 euros, very easy to fit took me under an hour,(as my wheel is a driving force pro i use the Leo Bodnar cable and DXTweaks 2 for calibrating pedals) for people with G25/G27 wheels calibrate pedals as normal in windows control panel. All seems fine and will test again this afternoon with praccy for Golden Valley race.
