I have an issue front accident damage replaced Ultrasonic sensors.  ISTA says Short Circuit but if connect sensor it says error not present, I have checked wiring and no short, traced all way PMA module in rear, left and right sensors are working is ISTA, the four center ones are the issue.  ISTA says No sensor fitted.   However when I connect the sensor the left and right sensors stop working with error 511.  Do I need to recode the module?  Change date?  Not sure what to do next.  As I add the sensors they should come on line and show a distance in diagnostic but hey do not they say sensor not fitted which indicates programming may not be correct.  Sorry this is a long post!

Update - I have reassembled after testing all wire connectivity.  The system works on start for a few seconds then errors and terminates, it appears to be working.  I attach grabs from Video.  Any ideas, coding?  The car has park assist and park distance.
