hello,

did you solve this problem? I have a 6FBRE12, model 2014 with 800 working hours.

You use the truck without problems, but in some moment the steering is disconnected when you turn left and stops work to that side, but if you turn to the other side works ok. When the error appears, the steer in left direction does not work anymore. this is sporadic, you can use the truck a lot without error, and then the error appears 3 times in 10 minutes.
If you turn off the truck, and then turn on, the error disappears and appears again as sporadic.
