Does firmware 1.11 have a problem with the distance sensor ?

I have built the autopilot configuration. The program recognizes that the distance sensor is connected, but it does not work. The car runs into the wall. I am using the new firmware 1.11, and both the brain and sensors are updated. Is there something wrong with firmware 1.11 ? I had not tried the autopilot using the older firmware rev, so don’t know if the problem is the firmware version or a bad distance sensor.
