We have a 2012 s630 bobcat and last week it suddenly beeped and the exclamation point on the display lit up. We lost right forward motion. I also noticed that the speed management also pops up now (we never used it). We took it in for service and were told it was a solenoid. This solenoid is onbackorder, but I managed to hunt one down ($300 later)...the solenoid was replaced and it worked right for about 30 minutes. Here I sit again with our loader down. Anyone ever experience this, our know what it could be?? I'm really hating this electronic selectable joystick now. Thanks!!!
