807 2.0 HDI 2007 Power steering comm failure

[rojocapo]

Hi,

My PP2000 scanner says that there is no CAN communication to the power steering controller. I recently drove 3900 kilometers over pretty bad roads through Argentina, Uruguay and Brazil, at over 120 km/h. Would it be possible that the vibration has messed up the wiring harness or the power steering electronics? Would a blown fuse trigger that error?

Thanks in advance,
