My car (2022 V60 T6) is currently at the dealership for the 3rd time for this issue.
As with your car, mines causes the petrol pump to click off roughly every 4 litres when refueling.
They have booked my car in for the full week. I'm not sure they actually know what the issue is.
Once I have the car back I will let you know the outcome
