Hello,
we have the similiar behavior on S60 T6 Polestar 2018, where we try to "catch it", but as you say, it happen occasionaly and therefore it is very hard to find the bug there. It looks like some kind of issue in Volvo DDM/PDM software connected with commands sent from VDD in the "right" time. Can you see any speciffic conditions, before it happen?
